Who Needs The Red Sea?

 

The sea was a perfect flat calm. Not even the faintest ripple disturbed the serene surface of that mirror like water. The air was equally still and tinged

with a salty mist as the red sun laboured slowly into the heavens for the start of another day. Only the deep blue of the cloudless sky hinted at the ferocious heat of the day to come. A tarpaulin was laid across the ground to help minimise the amount of sand left clinging to our bags and clothes at the day’s end. We had learned by bitter experience that no amount of careful planning prevented those all pervasive granules from adhering to everything in that humid climate. We assembled the tanks and regulators without speaking, as though nobody wished to break the magic of the morning’s silence. Quietly we donned BCDs, ran through a fast and noiseless equipment check, picked up mask and fins, and walked towards the waters edge. It was almost with a feeling of shame that we crossed the threshold from sand to water, and broke by our own movement that perfect flatness of the sea. Quickly we waded to deeper water, donned fins, and grasping the regulator between eager lips, slid below the liquids surface.

 

This was what we had driven so far to achieve. Weeks of anticipation and planning were reaching their moment of fulfilment. We dropped slowly, tensing against the cold ingress of water as it permeated the collar and cuffs of the wetsuit. We dropped through water as yet only weakly lit by the low sun, until, at precisely six metres below that calm surface, we struck the bottom. We stared out in amazement, before us lay a uniform bed of sand stretching as far as the eye could see, punctuated only by the odd crumpled Pepsi can and a single blue thong. Adjusting buoyancy carefully so not to disturb the fine particles of the bottom and reduce the visibility below four metres we followed the direction predicted by a compass towards our goal. We finned gently through that placid water in that early morning gloom, until it was possible to detect a faint hint of shape, a slight difference in colouration. As we moved closer the vague outline hardened, the colours became more pronounced, and at last she could be seen in her entirety. Our navigation had been unerring, we had found our goal. The majestic wreck lay flat on the sandy bottom, she was intact and fully twenty feet long, sitting upright on all four wheels. The seats designed to carry passengers at two riyals a time were still in place, though threadbare from many years of submersion. The glass was missing, and a hole large enough for a man to pass through was visible in her roof. This was no war sunk relic, nor a vessel which met grief on the outside of some uncharted reef in the midst of a storm, but rather a Toyota minibus carefully placed on the seabed to form an artificial reef. The success of the project became apparent as we slowly approached, and a startled sergeant major fully 6cm long dashed away from his lair near the steering wheel of the vehicle. Two sea perch came out of the gloom to investigate us, but rapidly turned away and disappeared from vision. We checked our gauges, six metres of depth, four minutes into the dive, and still an abundant supply of air……….

 

This is how many view diving in the Gulf of Arabia in comparison to the luxury of the Red Sea situated on the opposite coast of the Arabian Peninsula. But having been lucky enough to spentd more than twenty years of my life diving on both sides of Arabia I can tell you how much I have enjoyed each of the very different environments. The Red Sea is deep, part of the Great Rift Valley, and generally blessed with a more or less constant year round water temperature as well as tremendous water clarity. It is this feature that allows the coral reefs to flourish as the algae zooxanthellae which lives symbiotically with most corals and helps feed the polyps therein requires copious amounts of light in order to photosynthesise. The Gulf on the other hand is a shallow sea, and hence suffers considerable temperature variation throughout the year, something you will quickly realise if you invade those waters in January. Also the generally sandy bottom is prone to easy disturbance, especially by windy weather or storms, and consequently visibility tends to be much reduced. But that does not diminish the pleasure to be gained from diving in the Gulf.

 

It is here in the shallow water described above in the salty inlet of Half Moon Bay near Al Khobar in Saudi Arabia that I have seen large numbers of sea snakes ferreting in and out of the prawn and goby holes in the muddy bottom searching out a tasty morsel. Sadly man’s incursion and proximity to this environment has had an impact, and over the years the number of snakes spied has dropped dramatically. But the flat bottom is still home to many sea grasses, and these in turn provide the feeding and breeding grounds for many species. And nothing is more exhilarating than sitting quietly and watching the interrelationships of the species that abound in even these shallow and murky waters. I was always amazed to watch how the prawns and gobys shared the tasks of housekeeping in their unusual symbiotic relationship. Usually the goby would take on guard duty watching for predators as the prawn cleaned and extended their mutual home, a task that was rewarded by food donated to the crustacean by the fish.

An upside down jellyfish, one of the species you can see in the gulf.

It is in the Gulf that I have seen the unusual upside down jellyfish, so called as they lay on the bottom with their fronds pointed uppermost to feed. And in these same waters large and friendly squaretail groupers have followed divers regularly around, watching inquisitively while hoping for a free treat. Many people, probably accurately, disapprove of fish feeding but it is hard to refuse these loveable creatures as they sit on the sand supported on their pectoral fins and watch you closely with large soulful eyes. Be warned though, like every wild creature they can become aggressive feeders and bite, but you are unlikely to suffer any major wounds. Rather than teeth they are armed with upper and lower dental plates coated with razor sharp denticles, more closely resembling short cropped wire brushes than any pair of teeth. I was the victim of such an aggressive attack by a large and presumably hungry grouper. A group of divers had formed the habit of taking small tins of Viennese sausages with which to feed the fish, and obviously they quickly learned to identify the reflective cans with food. I had no sooner taken a tin from my BCD pocket when a huge and wide mouth grabbed my hand and the can, fortunately retaining only the latter as it sped quickly past. Even more fortunately no lasting damage was done as the fish disgustedly spat out the unopened tin some distance sustaining no damage to it while allowing me to retrieve and use the fish food. Hopefully after that incident the animal became more cautious and learned better manners and to wait to be served.

 

There are many islands in the Gulf, and many do have areas of reef around. But better still this body of water has been a shipping route for many centuries, and where there are and have been ships on the surface you will inevitably find ships underwater. And for me wrecks, (other than deliberately sunken 4 wheeled vehicles), offer the most exciting part of diving. That excitement is not from seeing what I can recover, and I do know of wrecks in Arabian waters still laden with bottles alcohol and plastic sealed carpets, though I will not repeat their locations. Nor is the fascination for me to spend time pushing myself to the limit trying to penetrate a potential death trap of cables, pipes and corridors. Rather I just want to watch as I am always stunned by the peace and serenity of a sunken vessel, and try to imagine what it was like as hysteria and panic abounded when the ship sank in the midst of a storm or after running accidentally aground.

 

Yes, the Red Sea is great, but so is the Gulf.

 

The Variable Volume Diving Tank System

Luxfer, the worlds biggest tank manufacturing company, announced recently their revolutionary range of advanced variable volume tanks which will become available worldwide during 1996. The concept is totally original and came as a complete suprise to the dive industry. According to Luxfer’s advertising, ‘the new
system allows buddies with entirely different breathing rates to start a dive with similar sized tanks and end with equal amounts of air’! The system also allows for carrying increased amounts of air when it is required, such as when deep diving or entering into overhead environments.

 

The basis of the system is a new synthetic material based heavily on proven carbon fibre technology. The material is said, weight for weight, to be around ten times stronger than steel, have elastic properties which make it practically immune to accidental damage. Being synthetic it is also totally resistant to seawater corrosion. Such is the faith in the new material that Luxfer believe that hydrostatic testing may soon become a thing of the past, or at the very least be required at much less frequent intervals, possibly once every ten or twenty years. Also because pigment is embedded into the structure of the material itself the tanks are immune to paint scratches, and they should look as good after 20 years use as they do on the day they are manufactured.

 

The implications of this new material are staggering. ‘Standard’ tanks will now weigh around 10 lbs, a fraction of their present day weight. This weight reduction not only means the new tanks will be easier to handle, but will allow the possibility of easy transportation. No longer will your car ride on its suspension stops when laden with dive gear. More importantly it will become possible to transport your tanks, (with the valves removed), by commercial aircraft. Contamination by moist air is no longer relevant, so you will be able to take your own tanks with you to the most humid dive resort

 

But most exciting property of the new material is its elasticity, which means the tanks can expand to almost one and a half times their nominal volume with no loss of structural strength. This means a tank rated at 80 cu. ft. at 2800 psi becomes a tank of 115 cu. ft. at 3200 psi, the maximum fill pressure on the tanks. This gives an overall increase of 53% of contained air. Because of the small outside dimensions of the tanks, due to the thin wall section, the overall buoyancy is similar to that of present day aluminium tanks. For example the largest tank in the range, at a nominal 80 cu. ft., has a rating of -1 lb when full, and +5 lb when empty. These figures do change when the tank is pressurised to maximum fill and capacity, and to allow for easy compensation on your weightbelt Luxfer supply a simple table to indicate both contained air and buoyancy at different possible fill pressures.

 

Luxfer will be releasing three tank sizes 50/73 cu. ft., 66/100 cu. ft., and 80/115 cu. ft. All tanks come with pillar valves designed for standard A clamps. Luxfer stated that in the future they intend to develop a series of high pressure tanks which will incorporate DIN fittings to fit the current trend in regulators.

 

This technology will not be cheap. Although prices are not yet finalised they will depend upon how well the new system is accepted, and hence the scale of production. However expect them to cost at least twice of what you pay for currently available systems. However in view of the VVTSs extended lifetime, and (future) reduced requirement for testing and repainting, the tanks may work out to be more economical than present day steel or aluminium ones, as well as presenting significant other advantages.

World’s Top (otherworldly) Dive Sites! (according to Lonely Planet)

I love top ten lists.  It might be top ten places to go, top ten gadgets for the next millennia or top ten blondes in the world’s for January 1962!  Either way, I suck them up and add to my my to do/to buy list appropriately.  Of course whenever I read a top ten dive site list – I pay close attention.  Of course you have your usual suspects from the Great Barrier Reef to the Red Sea, and usually I can say I’ve been to at least a couple…

Then I came across the recently published Lonely Planet most otherworldly dive sites. Now after diving for 15 years and traveling to every continent spare Antarctica (I’ve got my eye on you o’ cold one!), you might assume I’ve dived most everywhere.  Sure there are still a few big ticket sites I want to go to, but I would assume any not too esoteric list of dive locations I would have visited at least one or two!  However I am embarrassed to say that I can’t claim a single scalp on the below list .  I’ll be packing my reg’s and heading off soonest to fix this!

So here they are:

1. Great Blue Hole, Belize

This is perennially in the top three of any world best dive sites, I’m ashamed to say it is perhaps the location that I need to visit most for my diving cred.  Apparently a true marvel of a location. (nearest I’ve been – San Andres/Providencia Colombia)

2. Chuuck Lagoon, Micronesia

Always top of the list for wreck lovers.  Superb diving for most levels of experience and some excellent opportunities for tech divers.  My good mate Ross visited here a couple of years ago, I doubt he has done a ‘wall’ dive since! (nearest I’ve been – Puerto Galera, Philipines)

3. Manta Ray Village, Hawaii

Love me a Manta!  Surely one of the very top animals you can encounter underwater.  This looks like one of the best places to guarantee viewing. (nearest I’ve been – other side of the Pacific!)

4. Samarai Island, Papua New Guinea

Right on my doorstep – well my doorstep in Australia! I’ve been thinking about diving here ever since I heard about Mike Ball’s Expeditions running a live aboard there a few years back.  It has long since shut down due mainly to logistical issues.  I think PNG would be a marvelous dive location for a dive operation if you could crack the admin/log nut! (nearest I’ve been – Bali, Indonesia)

5. Palau Sipadan, Malaysia

Our good friend Kevin (who’s posts you will see here shortly) snuck over here a few months back.  Whilst it isn’t the easiest of places to get to – the diving is well worth the effort with marine life and coral second to none! (nearest I’ve been – Phuket, Thailand)

6. Cocos Islands, Costa Rica

To be honest I wasn’t very familiar with this location deep in the Pacific.  I’d heard of Malpelo Island of Colombia (top three on my list), but most of the diving I know about in this part of the world is on the Carribean side.  This does look an intriguing option though. (nearest I’ve been – again San Andres/Providenica, Colombia)

7. Gansbaai, South Africa

Now this is a close call!  If you wan’t to dive with big sharks, that are cranky, and came REAL close – this is where it’s at. If you’ve ever watched discovery channel for a day, you’ve probably seen footage of these great beasts up close – brilliant stuff. (nearest I’ve been – was booked to go diving here in December 2006, and the weather beat me out! :(

8. Ras Mohamed National Park, Egypt

I can definitely testify about the quality of the Red Sea.  Having dived up and down the Saudi coast hundreds of times I can say that the Red Sea is truly wonderful for diving.  Having said that, I’ve not dived out of Egypt.  Having lived so close for so long, I don’t really have a good excuse… (nearest I’ve been – Jeddah, Saudi Arabia)

9. Cocklebiddy Cave, Australia

For the hardcore cave diver (another speciality I want to complete).  I must admit I had not heard of this site having concentrated my efforts in Australia to the east coast.  Sounds like considerable training will be wanted for this one – adding it to my bucket list as we speak. (nearest I’ve been – Jervis Bay, Australia)

10. Rainbow Warrior, NZ

Now if I had of thought about it I would have dived this wreck when I was in NZ instead of getting acquainted with the local beer and *Ahem* wildlife.  It’s pretty cool that you can dive one of the most significant moments of this countries history. (nearest I’ve been – dive bars near the harbor ;)

Diving in Puerto Galera

I’ve wanted to dive the Philippines for a long time.  It was rumoured to have almost countless diving opportunities, beautiful inhabitants and all at a very economical rate.  This all turned out to be true, and whilst I’ve only glimpsed one small part of the diving on offer, it has left me lusting for more.

 

We were staying in Manilla for a couple of days with friends, and so I decided to go to the closest decent diving destination to Manilla. Avoiding flying meant that I could squeeze in another days diving into my vacation, so the decision was made – Puerto Galera here we come!

 

Getting there is simple enough, there is  a ‘Super Cat’ service which will take your from Manila by bus for a couple of hours, then onto a speedy catamaran to Puerto Galera (PG).  All in all it takes perhaps 3.5-4 hours to get there with Manila traffic having an influence upon this.

 

PG isn’t much to look at in itself.  The beaches there are average to non-existant, and the town itself is a little dingy, with a certain ‘other’ type of older tourist prevalent.  There are however countless diving operations which give some hint to the underwater opportunities.

 

We settled at AB Wonderdivers, which are a fantastic organisation run by Alice and Bjorn.  They operate a very slick operation and are two of the friendliest people I’ve met diving.  All their equipment is top notch, and the lunch on offer are fantastic.  Much better than your average dive cuisine!  They have two rooms (plus there is a somewhat affiliated hotel next door) that you can stay in.  They are basic, but clean rooms and of course ideally located to jump on their dive boats.  Many of Alice and Bjorn’s customers are repeat divers who have followed them from when they worked in the Maldives.  This gives you a good idea of how great the service they offer is!

 

The diving in and around PG is superb, with 20+ dive sites within 10 minutes boat ride.  It was such a pleasure to do a boat dive with only a 2 minute commute!!  There is a plethora of coral and underwater life around with the majority being of the macro variety.  The nudibranchs here are fantastic, and you can spend a great deal of time just exploring a small area looking at the small stuff alone.  Visibility while I was there was pretty good at around 15 metres, but I believe it gets better than this still.

 

I recommend the diving here for people that don’t expect to see whale sharks and mantas on every dive.  There isn’t a lot of the ‘big stuff’ around, and I didn’t see any huge dropoffs or walls of epic proportions.  It is however a great place to appreciate the smaller things you might otherwise overlook, and to practise the often overlooked art of macro photography.

 

There are certainly bigger name destinations to visit in the Philippines for diving.  But PG offers an excellent option for those that want a quick weekend away from Manila, or have a particular penchant for the smaller stuff.  You will be very well served to visit Alice and Bjorn at AB Wonderdive – let them know that Damo says g’day, and I’ll certainly be back one day soon!

 

The Cutting Edge

 If you are reading this website obviously you have an interest in diving and no doubt you will have heard something of technical diving and the advantages and disadvantages of breathing oxygen enriched gas mixtures. No doubt you will have also heard about the necessity of converting the breathing gas to heliox or trimix for deep diving to remove some or all of the problems associated with high partial pressures of nitrogen. You may even have read of the experimental techniques for very deep diving involving replacing some or all of that helium content of the gas mixture with hydrogen in an attempt to remove problems associated with helium at extreme depth. You may even have heard of the disastrous results that occurred from these experiments with hydrogen. You may well have read other articles concerning attempts to extend bottom time and depths while mitigating the dangers associated with diving. For example there is a resurgence of interest in rebreather technology using advanced electronics, making SCUBA equipment much less cumbersome and also providing the ability to custom select gas ratios. You may even have heard of the prototype ‘biolung’, a device which uses cultured living tissue to extract dissolved oxygen from water which operates in much the same way as the gills of a fish. Almost invariably you have witnessed the flooding of lung tissue with oxygenated fluid to allow oxygen to diffuse directly into the blood, a technique used successfully with rats in the laboratory, and portrayed so vividly in the film ‘The Abyss’. But still you may not be aware of the latest cutting edge of experimental diving.

 

Try to imagine the concept of a true ‘manfish’, to use Hans Hass’s terminology. A person unencumbered with heavy diving equipment able to simply walk to the waters edge, attach some lead to offset a human bodies natural buoyancy along with that of any thermal protection worn, don a mask for vision, and fins for mobility, then simply takes a ‘breathing’ pill before entering the water. Is this a fantasy scene from Waterworld or is it a possible reality? Is it truly possible to dive without heavy tanks of air or without using a regulator? Could a person swim freely in the sea with minimal equipment while breathing with the ease of a fish.

 

Surprisingly this science fiction scenario may soon be available; the technology according to its inventors is not very far away. Like so many things in life the concept of a manfish starts with a remarkably simple idea. The diving pill relies on a liquid, hydrogen peroxide to be precise, H2O2, a common chemical which will be found in any school science laboratory. The liquid is an oxidising agent that breaks into two components, water and oxygen, when mixed with any acid, liberating at atmospheric pressure 22.4 litres of oxygen from every 34 g of the substance. The idea is that hydrogen peroxide contained within some slow release mechanism is swallowed into the stomach, where the hydrochloric acid causes the chemical to decompose and provide a continuous supply of oxygen, and water. Imagine a near endless supply of life preserving oxygen without any dangerous side effects.

 

The major problem has been to find a suitable semi-permeable membrane with which to contain the peroxide. The material would need to allow the chemical to diffuse into the stomach acid at a controlled rate to provide an adequate supply of oxygen, without producing too rapid a release of gas. Too rapid a release could produce very unpleasant side effects, not the least of which would be the worst case of ‘wind’ in history!

 

The manufacturer actively involved in research into ‘SCUBA free’ diving is a Swiss based research company headed by Jorhanson, Olaf, Krich, and Enrich, four university friends.  For many years they worked exclusively for the military on cutting edge technologies, but now are delving into the field of recreational diving. They now believe that they have discovered the key to the problem of the peroxide release. The answer comes in the form of a new type of biodegradable plastic manufactured specifically for internal sutures, for holding different layers of soft tissue together after surgical procedures deep within the body. The material, known as Polyglactin 910, is manufactured in the United States and it has now been successfully produced in sheets ranging from 4 to 10 microns in thickness. This material appears to provide all the necessary qualities required for the external membrane of a breathing pill.

 

The breathing technique requires a degree of learning, and I would imagine initially at least there would be some discomfort in this adaptation. The oxygen is obviously generated within the stomach, and must pass from there up to the larynx, before it can enter the trachea and lungs. This means you need to learn a sort of belch breathe mechanism. Since the gas would be pure oxygen the amount required to enter the lungs would be very small in order to maintain normal body metabolism. This fresh oxygen mixes naturally with the gases retained within the lungs. The fact that the pill generates pure oxygen however does lead to complications and to severe depth limitations due to the potential for oxygen toxicity. To counter this depth limitation the company is researching a method of releasing nitrogen alongside the oxygen to generate something akin to variable ratio compressed air. Obviously any increase in gas volume would increase the necessary transfer rate of gas from the stomach to the lungs.  In the words of Olaf, one of the directors of the company, and a keen recreational diver, “the trick will be to allow sufficient nitrogen generation to remove the danger of oxygen poisoning, while not making the increased gas load which needs to be transferred from the stomach to the lungs uncomfortable”. But he states that is future improvement, but the oxygen releasing breathing pill is being tested now.

 

The carbon dioxide generated by the body metabolism needs to be removed, and there are two options for doing so. In the first the diver simply exhales into the water, but this then requires a much larger gas volume to transfer from stomach to lungs. Although possible this depletes the bodies own nitrogen reserve so the percentage of oxygen would increase throughout the dive further restricting depth. Olaf now states that this problem has now been overcome by the second option, utilizing a breathing ‘cup’, a small and simple tube both ends of which are gripped in the mouth. A diver exhales through the one way valve passing the gas through a CO2 scrubber which then cleans the gas before it is re-breathed back into the lungs. As a consequence of using this ‘cup’ the nitrogen level remains constant and the diver leaves no bubble trail, a definite bonus to any military application as well as for an underwater photographer.

 

According to Olaf research is already at an advanced stage. Rats have been submerged with many surviving for almost an hour by using a suitable pill. Obviously the rate of oxygen release needs to be a function of both body mass, and basal metabolism, and this rate is controlled by a combination of the membrane thickness as well as its surface area. Goats were chosen for the next stage of testing because of their similar physiology to that of humans, the same reason for the choice made by Haldane many years ago when he did his initial research into decompression sickness. These experiments have not yet achieved the same level of success. As Olaf explained, “the major problem lies in teaching the animal a new way of breathing by gulping gas generated in the stomach. Rats were relatively easy. They were fed a capsule and then their jaws were sealed and fixed closed with one way valves fastened into their nostrils to allow for the exhalation of carbon dioxide. With the goats we tried to use the capsules as they would be used with man. Unfortunately all the goats used so far in the tests have found the transition from surface to being totally submerged too traumatic and drowned.”  It has been suggested that a small amount of diazepam, or some similar muscle relaxant, may help alleviate this transitional period, but research here is still in early stages.

 

Olaf seriously believes that the company will have a marketable, safe product in the near future. So who knows, do you really need to buy that new top of the line regulator? It could well be replaced before long with a simple packet of breathing pills.

Diving in Saudi Arabia

It is perhaps a little known fact that the diving is fantastic in Saudi Arabia.  It is certainly a country better known for its ‘out of this world’ conservatism and endless sand dunes, but it does also share a coast line on the Red Sea.  I was fortunate enough to dive in Saudi for a couple of years whilst working there, and also setup www.riyadhdivers.com which is still run by my good mate Manfred.

 

To talk about it briefly, there is also diving on the east coast in the Gulf around Bahrain.  I’ve taught rescue courses here as there are lots of sandy beaches, but to be perfectly honest, as it is off Dubai, the diving here is pretty poor.  Very little coral or marine life and pretty poor visibility year round.  For me it was always an easy choice to head to the west coast and The Red Sea.

 

The Red Sea is most famously known for the diving out of Egypt.  Sharm el Sheikh and Hurghada are a couple of the most frequented diving spots used by European divers and are both massively popular.  You can also access the Red Sea from Aqaba in Jordan or Port Sudan in Sudan.  The Saudi Arabian port city of Jeddah is another great option, although it can be more difficult to get to.

 

While Egypt is a piece of cake to get into, Saudi Arabia, for non-muslims or residents is far more difficult.  The country has made small steps forward to liberalise the tourism industry, and some operators like Dream Divers can assist in this process.  Don’t expect swathes of freedom of manoeuvre, as you will often be escorted from hotel to dive boat.  What was most common for me to see there were dive groups from Italy or Germany on a package deal where they would top and tail their journey in Jeddah, and spend the remainder of the time on a liveaboard boat.

 

Once you are in the country I can recommend a few destinations:

 

Jeddah:

This is the main dive hub in Saudi, and there are probably half a dozen operations running boats out of here.  It is very easy to get on a day trip, or find a liveaboard to cruise on for a week or so.  For those wanting a little slice of the west (sans alcohol) and shore diving, you should investigate the Al Bilad and Sheraton hotels which both offer beach diving, and a more European beach atmosphere – albeit for a price.

 

Al Lith:

This is a small village a few hours south of Jeddah.  It is far less developed but has some great diving opportunities nearby.  From here you can easily find boats going to the Farasan Banks or Farasan Islands which are near the border to Yemen.  This is easily some of the best diving to be found in Saudi, and if you have the time is well worth exploring upon a liveaboard.

 

Yanbu:

You can fly into Yanbu which is north of Jeddah from Riyadh or Jeddah itself.  The town is more developed than Al Lith, but you have fewer options for diving as of last investigation.  Some of the bigger dive operations running out of Jeddah may have a boat up there, or you can find a local fisherman who’s boat you can hire for the day.  This is slightly more off the beaten path.  But the diving here can be just spectacular, with no other divers around.

 

It is well known that diving in the Red Sea is world class, the diving out of Saudi is certainly no exception to this.  When you are diving the northern parts of the Red Sea out of Egypt in particular, dive sites are often crowded with half a dozen boats sending divers in.  This is definitely not a problem out of Saudi, and it is a rare co-incidence to find more than one dive boat on any given site.  Whilst it is harder to get to than many places – for the intrepid diver the rewards can be certainly well worth it with undiscovered dive sites aplenty.

The truth about sharks

Like them or loath them, you cannot ignore them. No sea creature has caught the imagination as successfully as sharks, they are both loved and feared throughout the world. Much has been written on these strange ancient creatures, though unfortunately many things that you read are ill informed. For that reason below is a list of ten facts which you probably did not know about sharks, and probably didn’t want to!

 

1.         Not all sharks are intelligent, though many of them are known to school.

 

2.         The great white shark is often wrongly described as a mankiller. Reliable statistics prove that almost half the people eaten by white pointers are in fact women.

 

3.         In a recent study undertaken around the coast of California it has been shown that the two biggest motivators to stop people swimming in the sea are sharks and toilet paper.

 

4.         Sharks were in no way implicated in the sinking of either the Lousitania or the Titanic. However sharks did have an impact upon the crew of the USS Minnepolis at the time she sunk.

 

5.         Although a dogfish does not bark it is known to chase and eat catfish.

 

6.         The shark as a species of marine animal has a reverential place in the ancient literature of many civilisations. Strangely ancient literature from Switzerland includes not even a single mention of sharks.

 

7.         Among tests conducted on various groups it was discovered that sharks will not attack members of the legal profession and insurance salesmen. It is believed that this is due to professional etiquette.

 

8.         Strangely no single mention of sharks is made in the ancient literature of Andorra either.

 

9.         The old joke, “what is yellow and dangerous?” (Answer: shark infested custard) is now believed to have no basis in fact. It seems that no single species of living shark knows the recipe for custard.

 

10.       Sharks of antiquity were known both to inhabit fresh water and also to have been excellent climbers. This has been proven as fossilised skeletons have been found high in the rock   strata of the Grand Canyon.

Five things to keep you alive whilst SCUBA Diving


Diving is dangerous, a shark might eat you, your ears and possibly lungs will explode.  It is well known that massive sea urchins take divers almost daily!!  Hopefully you are still reading and detect the slightest little bit of sarcasm. Diving is one of the easiest least demanding activities that can be enjoyed throughout the oceanic world.

 

I was recently inspired by a 70+ year old diver that I met whilst dving in the Philipines. He was German, and had been diving for 40 odd years!  I wish I had taken a photo of his BCD as he had been using it for 32 years, truly a classic!!  This gentleman (and his wife also), had clearly been enjoying diving without encountering any of the things that could negatively influence your diving.

 

1. Breath!

 

This might sound ridiculous, ‘of course I must breath underwater’ but what you must do is breath constantly – DON’T HOLD YOUR BREATH.  This is for me the number one rule for diving.  If you maintain slow, deep breaths you will extend your bottom time through effective use of your air, but also avoid any lung injuries.

 

As you may know, or will learn from your instructor, air within your lungs will expand when you ascend.  So it’s important that it doesn’t expand beyond the capacity of your lungs – or else you will be in trouble.  Thankfully the antidote is incredibly simple, do what you’ve done since you came out of your mum – breath!!

 

2. Ascend like molasses

I like to take my time ending a dive.  From the point that I decide to make my descent, I will take as much time as I can to reach the surface.  Why?  Well I love diving, and want to stay down as long as possible.  But also, if you ascend too rapidly (greater than 18 metres per minute), you increase the risk of suffering Decompression Sickness (DCS).

 

Without going into the physics too much: when you change depth/pressure gasses will want to change where they are to equalise the pressure, they will do this quicker the faster you ascend.  What one DCS basically is, is when a bubble forms and fixes itself somewhere it shouldn’t be.  You can avoid this very easily by ascending slowly, doing a safety stop and following point 3.

 

3. Plan your dive – or listen to your watch!!

 

Unfortunately we cannot stay underwater forever.  Our tanks will run out, but also nitrogen will limit the time that we can stay submerged.  This is related to the point above as we want to avoid those pesky will bubbles!

Divers have used tables for the longest time to determine how long they can stay at certain depths for.  In your initial dive course you might learn about this method, which is a very conservative way to ensure that you don’t absorb too much nitrogen. Tables, for better or for worse, have been largely replaced by dive computers for recreational divers.  Dive Computers/Watches allow for constant recalculation of your dive profile which will almost always extend your bottom time.  Dive watches will also give you an audible warning when you are approaching your diving limits giving you the opportunity to start your slow ascent.

 

4. Keep your hands to yourself!

Almost without exception, injuries caused by creatures under the water have occurred through people touching things they shouldn’t or provoking animals.  Most people don’t know what fire coral is, or appreciate the severity of a sting from certain urchins – but don’t worry, you don’t need to.  By simply not touching things underwater, you don’t have to worry about what might cause you harm.  Remember that turtles are not taxis and sharks shirk freeloaders!

 

Another excellent reason to not touch things is marine conservation.  The greases on your hands may in fact cause harm to corals, and your interaction with animals may influence their behaviour underwater.  Many stories are known about over-friendly groupers that expect divers to give them treats – just keep that in mind next time you are encouraged to feed the fish!

 

5. Dive within your limits.

This includes your dive planning but also knowing what you are trained and comfortable doing.  Low visibility, night, currents, cold water may all make your diving experience a little more complicated.  There are courses that will prepare you for most situations, and I recommend you learn as much as you can before putting on your BCD.  Divemasters will always help you out with advise and will often also escort you in challenging situations.

 

Dive regulations are not always enforced throughout the world, and there is no one underwater policing your actions.  It is ALWAYS the responsibility of the diver to look after their own safety, and to dive within their limits.

 

Keep these five points in mind when you are diving, and of course follow the guidance of your divemaster and diving will always be the great fun activity it is supposed to be.

Dive Buddies – my mentors and mates in diving

I’m not sure how many people I’ve met traveling and teaching with diving.  Most relationships I’ve had have been fleeting trips on boats or at dive sties, but as with any encounter some of these relationships have had a tremendous influence upon me as a diver, instructor and an individual.  There are three people who have had different impacts upon me specifically and who have made me the diver/instructor I am today.

 

Pete being 'Rescued'

My Dive Father

When I decided to take diving more seriously I was told to go talk to Pete who was famous in Riyadh (of all places) for teaching diving.  Upon meeting him I said that I wanted to become a divemaster.  I didn’t really understand the ‘rank structure’ as it were, and thought that a DM was the top of the pile.  Pete quickly corrected me and said that I should aim at becoming an instructor.  So that was that, I was going to become  a diving instructor!

I was only an Advanced Open Water at the time, and hadn’t done a dive course in seven or eight years, but within weeks I became a Rescue Diver and started my Divemaster apprenticeship.  Pete mentored me through all of this, and his passion for diving was always evident.  He has encyclopedic like knowledge of things underwater, but seemingly only a dozen or so jokes!!  It soon become apparent that Pete loved teaching, not the administration or logistics, and from this riyadhdivers.com was born.  Under Pete’s guidance I organized my first dive trip, and all of the headaches that come with it.

My apprenticeship DM with Pete was no easy task, and I’m sure we completed the requirement three fold (I think it lasted a year!), but we were so well repaired for our later IDC/IE that it was certainly worth the effort.  Pete tells countless stories of people whom he has taught to dive becoming instructors, and I’m very proud to count myself as one of them now.

My Dive Brother

I can’t remember exactly when I first met Manfred, but it may well have been in the classroom for our Rescue Diver course.  It was the first of many classes that we would take together as we completed our Divemaster and Instructor qualifications together.  We jointly ran Riyadh Divers with Pete and pretty much team taught on all of our first year or so of courses.  Diving and teaching so much together gave us almost a level of telepathy underwater, we barely need hand signals but if we did we manage to explain to each other the most peculiar idea or instruction.

Manfred, although a peer whilst diving was instrumental in the development of my skills as a diver.  The main reason for this is our competitiveness.  We competed to swim the fastest, to demonstrate the skills the most perfectly, to teach dive theory the most effective way.  We’re always quick to point out each others faults.  I think it was due to this competitiveness that despite us having by far the fewest dives on our IDC, we received the highest grades.

One day, Manny and I will open our dream resort somewhere warm surrounded by bavarian beer and bikinis – and also some diving!

 

My Diving (super) Uncle

Witold, Manfred and I

When Manny and I trundled of to complete our instructor course, Pete had ensured we were well prepared spending considerable additional time with us in the pool and in the classroom.  Although we still weren’t sure what we had in stall, we were nervous about passing (after all it WASN’T cheap), and we weren’t sure exactly what we were getting ourselves into.  When we first met Witold Smilowki, we were taken back a little by his stature and also his strong Polish accent.  After only a day or two, Manny and I were both saying ‘I wan’t to grow up like him’!

Witold was an impressive individual.  He travelled the world teaching dive instructors (more than 5000!!) freelance. He also taught technical diving instructors.  He also happened to teach martial arts and skiing.  If I remember correctly he also hoped to teach skydiving one day having completed hundreds of jumps.  Witold came across as a bit of a superman, and someone who’s advice we were going to listen to in hope that some of his magic might rub off.

When Manfred and I struggled with long wetsuits, steel tanks and demonstrating hovering, Witold quickly reminded us that an instructor should not be held back by something as simple as his equipment!  We quickly nailed that hover (I literally practiced for hours)!  I learnt much about the dive industry from Witold, and if I can have 1% of the influence he has had upon the industry, I will retire a happy diver.

 

Buddies in the oceans and above

Pete, Manfred and I will one day dive again together – I’m sure of this.  Whilst we now live in three different countries, our paths will cross and we will jump in the water again together.  Unfortunately I won’t get the opportunity with Witold who passed away of natural causes in March 2011. He will be missed by the thousands (literally!) that he has taught and dived with.

In diving you have buddies in the water, and buddies who you will have for the rest of your life.  Learn from these individuals and grow with them.

Thanks Manny and Pete, and RIP Witold.

What equipment do I need for SCUBA diving

When it comes to diving equipment, you are going to be overwhelmed with the amount of variety that is available to you. It is worthwhile remembering that any new equipment that you purchase will have met the highest of safety standards (unless perhaps you are buying in Siberia or rural China!) and will perfectly safe providing you don’t exceed recreational diving limits. Of course you should also keep your equipment serviced, and wash with fresh water after any dive trip.

Keep in mind that most dive stores make a good portion of their money, if not the majority, from equipment sales. It will be in the interest of your divemaster/instructor to sell you equipment as they may receive a commission for this. Of course there is absolutely nothing wrong with this, and I’m sure that they will give you very good advice as to what you should purchase and make sure it fits appropriately. If you feel that they’ve provided you a good service, than bolstering their (very meager) wage through a small commission I think is quite fitting.

So what equipment do you need? For the beginner, still finding their feet I would recommend the following personal equipment:

  • Mask/Snorkel
  • Fins (boots if required)
  • Wetsuit
That’s it! This small investment can ensure that you are always comfortable when you are diving. You will be familiar with the gear and as a beginner this will add to your comfort underwater. These are often rented as a ‘set’ so it will also assist in lowering the cost of diving. If you are just starting with diving and perhaps aren’t sure if you are going to do it very often, I would suggest these purchases to start with.
When you get to the next stage, and you’ve bought the above and have perhaps 20+ dives under your belt, it may be time to start looking at the next items for purchase. The price does go up at this point, and depending on your personal style, budget etc. the variety of choices can be overwhelming. So what gear are we looking at now:
  • BCD (Buoyancy Control Device)
  • Regulators
  • Computer
You could spend as little as $1000 or as much as $20000 buying the above list. Before you buy this equipment, I suggest you ask yourself the following questions: Do I plan to do any more specialized diving (cold weather, deep) in the near future? Do I plan to do lots of diving whilst traveling? These questions will help you to figure out exactly what gear may be most suitable for you. Whilst it is easy to get very enthusiastic, it is very worthwhile to know that you are going to get effective use out of your equipment. Trust that there are millions of dollars of equipment sitting idle in people’s garages!

When I dive, most of the time if I’m traveling I just take my trusty Suunto D6, in fact this is always in my backpack with me just in case! I’m content hiring gear much of the time unless it’s a ‘dedicated’ dive holiday and the burden of carrying gear is outweighed by the cost savings involved.
