My point here is to emphasize value in continuing education and diving with the supervision of a scuba instructor. As you head out on your journey of scuba diving you will gain more experience and knowledge under the wing of a scuba instructor. Just like anything else, the lesson is so much greater with a mentor than striking it out on your own. The scuba instructor will provide you insight that would take you hundreds of dives to get a good handle on. Plus, the scuba instructor will share their own stories with you. Everyone loves stories that we can relate to.

There are things from each course you will take with you on your own dives. I guarantee that with most of the dives you are on will be able to implement something from each course you take, beyond the open water class. This could be from tying a knot on a shipwreck that you learned in your search and recovery class. Maybe you are in the middle of the quarry and you were ‘turned around’ due to the excitement of an underwater object and you grab your compass to take a reading to get back to shore. Or maybe you are out in the beautiful ocean on vacation and you see a newer diver go through stages from excited to worried way to fast. Without letting things go too far that will create some type of injury you make an approach to help the diver with what they need without making the diver’s worry noticeable. You would have never be able to do this without taking the rescue diver class after your Advanced Open Water class. Who would have guessed you needed anything you learned?

Now you can see some of the value of continuing on in classes you know you will enjoy. You never know you just might enjoy the challenge that comes with these classes and move yourself through the Professional ranks like I did. Others will just continue learning and becoming a more confident diver. That is something you cannot put a price tag on. You can enjoy years of endless excitement and relaxation.

Characteristically no wider than 450m, the Ribbon Reefs are part of the Great Barrier Reef Marine Park and are covered in colourful corals that attract a plethora of reef life big and small, with sandy gullies separating them, themselves containing interesting critters.

The Ribbon Reefs are generally quite shallow, coming up to as high as 5 metres below the surface from a sandy bottom that is between 15-20 metres below the surface. With great visibility year round and mostly calm sea surfaces, they are the staple of many liveaboards and provide fascinating Australia scuba diving opportunities for all levels of diver.

Highlights

One of the most famous Great Barrier Reef dive sites and a spectacle to behold, Cod Hole, as the name suggests, is a dive site famous for cod. Giant potato cod to be exact. What makes this site special is that the giant potato cod are virtually domesticated thanks to 2 decades of being fed by divemasters. There’s something special about a 60 kg fish swimming right up to you for a nibble from your hand. During feeding time everyone joins the action as coral trout, sweetlips, triggerfish and trevally also try to muscle in on the action.

Steve’s Bommie is a bit of a legendary dive site. The ballade of Steve varies according to who’s telling the story, but the common thread is that Steve loved this bommie, came to an untimely end and had the bommie named after him. A memorial plaque can be seen at 25m where most divers start on this site. Legends aside, Steve’s Bommie features a wealth of schooling action, big fish and macro life. Cruising barracudas, whitetip reef sharks and possibly even minke whales will leave you wanting to look everywhere at once.

The Temple of Doom is another peculiarly named Ribbon Reef dive site. Aside from macro action on the bommie itself, pelagic fish are a constant and you’ll have to ration your time between the reef and the blue. Shark sightings are common as are large rays and bluefin trevally of the 70 cm plus variety.

Diving Season

Due to Queensland’s tropical climate, any time of the year is a good time to dive the Ribbon Reefs. Water temperatures fluctuate between 22°C in winter and 29°C during summer. Visibility is good year round, with best vis from September to November.

During the wet summer months rainfall is moderate but usually limited to early mornings and later afternoons. The dry winter months see little rain. Surface conditions are always calm, but can become moderate during winter.

Obviously, we don’t want to be the ruin of the beautiful oceans that we’re so fond of exploring. Unfortunately, some popular dive spots have become ruined over time because of poor management and irresponsible divers.

Skills, training and knowledge

Responsible scuba divers possess adequate skills. This requires practice and training for good buoyancy control. This is important especially when diving sensitive environments like coral growths and shipwrecks. You should avoid disturbing marine life, touching them – unless you are certain it is safe and OK for both you and the marine life – and getting in entanglements. Many organisms are vulnerable to even the slightest brushes.

Planning and preparing for dives is vital – don’t put yourself or others in danger – not to mention marine life.

Dive within your means (training, ability and confidence level). You should be familiar with your equipment and know how to use it.

Your equipment should be streamlined. Dangling gauges and accessories are hazardous to you and to marine life.

Take specialist training – you need additional knowledge and training to dive overhead environments (such as caves and wrecks) or to venture to greater depths.

Responsibility and good practice underwater and on land

Do not take souvenirs and artifacts. You may – often unknowingly – be disturbing marine life by taking items out of the water. Collecting is also prohibited by law in many areas. Follow the popular saying: “Take only pictures and leave only bubbles.”

Learn about marine life in the areas you’ll be diving. Listen to professional guides, safety briefings and dive briefings.

Respect local customs and laws. If the reefs are out-of-bounds, there is probably a reason.

Do not litter or throw objects into the ocean. Litter is a hazard to marine life and to people. You can also help by picking up refuse and recyclables on the shore. Get involved in cleanup campaigns on shore.

Take advice from local professionals and follow their instructions.

Dive with responsible operators. Do some research. There are various national and international certifications and awards for dive shops, schools and resorts for good environmental practices.

Get involved with conservation projects – either in your local community or during your travels.

We just got back from this dive today. I live in Tappahannock, VA so this was almost a local dive for me.

We drove over to a Dennis’ river house at (near Coles Point, Virginia) he took his boat out to site. We were supposed to meet another guy at the site who had experience diving this sub. We had no problem finding the site and mooring to the mooring buoy (Blue and White and clearly labeled). We were there at 11:30am in time to dive at the recommended High, Slack Tide. Our contact never showed?

Conditions were PERFECT. Very smooth water, warm, clear day. It hadn’t rained in days. There was no appreciable surface current! There were 3 of us (John, myself and Dennis). We wanted to leave someone on the surface so John and I made 1st dive. Visibility was a bit better that I had psyched myself up for (maybe 8 feet?)

We all had HID lights (I would NOT make this dive without HID). Our prep experience was several trips to Cooper River, SC doing shark tooth dives. We were as comfortable as to be expected with zero viz diving.

We surface swam over to small orange ball that was ascent/descent line connected to the Conning tower. You are NOT to moor to this line! Be mindful of jelly fish and fishing lures around the down line (We all wore full wetsuits – I wore 7/5 mm hood and gloves) Water temp was very comfortable 79 degrees F.

As I reached 60 feet I still could not see any signs of wreck. It was only at 66 feet before I saw Stainless Steel base that down line was tied off to. We were amazed by the surviving wooden slates lining inside of Conning tower area. This has been submerged for some 57 years! As this was our 1st time here, we stayed pretty near conning tower and didn’t venture too far fore and aft but did descend to 79 feet to get a look at the HEAVY silt! It brought a new full appreciation of how bad silt could be! I did manage to locate the missing OMS Wreck Reel we were told about and recovered it. The owner promised to buy drinks for whoever recovered it?

We ascended and after almost an hour Surface Interval then Dennis and I made the next dive leaving John to mind the boat. Again we saw Jelly fish on descent line and managed to stay clear of them. We again circled the conning tower but didn’t go far forward or aft but it seemed most of the actual deck disappeared into the silt quickly.

All in all it was not near as difficult as much of the available literature made it out to be BUT it is a very poor viz dive and you can not bring too much light! We did have GREAT Conditions and I imagine it doesn’t get much better.

I am sure that it would be far more difficult if current was stronger!

I wouldn’t want to do that type diving every day (we just got back from a week and 24 dives in Bonaire!) but it was a great day trip!

If you have any Questions about the U-1105 feel free to email me!

Snorkel
It might seem strange wearing a snorkel when you are 30m deep, but it is a useful piece of gear when you are on the surface. In choppy water you can use this to save the air on your back!

Fins (not Flippers, please!)
Another simple, but useful device. In short by increasing the surface area of your feet they allow you to push yourself through the water more efficiently. But be aware that buying fins that are too big can cause leg cramps.

Wet Suit / Dry Suit
A lot of diving takes place in water that is uncomfortable to swim in for too long, so we divers wear exposure suits to keep us warm. By staying warmer, our divers are more comfortable and they last longer. Wearing exposure suits also protects us from abrasions if you brush against coral, wreck surfaces and so on.

There are 2 main kinds of exposure suit. The wet suit is used in warmer waters and allows water into the suit, but slows down the movement of water around the body – it is only getting in and out through the edges. This gives the water chance to warm up and keep near to your body, rather than rushing off into the sea.

In a dry suit all of the suit is sealed so that (hopefully) no water enters the suit – only your face is exposed. These are suitable for very cold waters, especially with the addition of undergarments for extra warmth.

There is also the semi-dry, which is a half way house. The seams are almost as good as a dry suit, but water can get in, allowing only a little movement of water.

Air Cylinder
Air and special mixtures of air, but not oxygen! Well almost, some decompressions are done oxygen at shallow depths, but for most divers it is just straight air, that has been dried, cleaned and compressed. These steel or aluminium cylinders can be quite weighty, but are our way of carrying our own air supply.

Regulator & Gauges
Attached to the cylinder, the regulator takes the air from the cylinder and provides it to the diver’s mouth. At the same time it also reduces the pressure from the high pressure inside the cylinder to the same pressure as the surrounding water, to make it comfortable to breath.

The gauges that are attached show the diver how much air is left and also the current depth of the dive.

Weights
It might seem strange to add weights to yourself before jumping into the water, but these reduce your buoyancy to enable you to adjust it throughout the dive. You want to be slightly negatively buoyant in the water when your buoyancy aid is empty.

Buoyancy Aid
This is not a life jacket, but an aid to allow divers to remain neutrally buoyant throughout the dive. By adding air as you descend, you maintain neutral buoyancy. This means that you hover in the water, rather than trying to fight to swim up or down.

There are loads more accessories and bits of diving equipment that you might want to add to this essential set-up such as diving knives to prod and poke and torches to see in cracks and crevices. Or maybe you want a fancy diving computer? There is a wealth of advanced diving gear to look at, if you want to know more, visit our diving equipment blog to uncover more information.

One of the best Caribbean wreck dives is the wreck of the C/S Charlie Brown on the island of Statia (St. Eustatius). Statia is only a quick 10 minute plane ride from Saba. I truly love vacationing on Saba. It is well away from the crowded reefs like Bloody Bay Wall on the Cayman islands or Palancar reef on Cozumel.

In its hay-day the C/S Charlie Brown spent almost 50 years lying fiber optic cable around the world. She was built in 1950 and is 327 feet long with a beam of about 41.4 feet.

The wreck of the Charlie Brown lies in 98 feet in water lying peacefully on its side. This wreck offers advanced divers, wreck divers, and underwater photographers the opportunity of a life time to watch everything from sea turtles to nudibranchs on the outside of the wreck.

For those of us who are more advanced, exploring the lone hallway that runs down the middle of the wreck is truly breathtaking. This hallway is wide open and runs about 120 feet through the wreck. Once inside you must visit the cable tanks and galley or move all the way forward to explore the reel room.

Unlike most wrecks the Charlie Brown was purposefully sank to form an artificial reef. But, she was not completely salvaged before the sinking. This now provides a look and feel of a real ship wreck.
Now, a little about how to get to Saba to start this dream vacation; Saba is what is called the Dutch Caribbean. The best way is to book your airfare to the island of St. Maarten. (SXM). Once you are on St. Maarten you will have two choices on getting to Saba:

* Take the Winair flight to Saba
* Take the 2 hour ferry to Saba.

Everything is really close. Saba is only 5 square miles while Statia is 8 square miles. You can get to most dive sites within 15 minutes. Saba is a volcanic island with spectacular lava tubes underwater. The best way to truly explore these Dutch islands is to start at Statia for a couple of days, then move on to Saba and end up at St. Maarten. St. Maartin has a great rain forest and this makes a great day to decompress after all of the diving.

Benwood – The Benwood is perhaps the oldest scuba diving wreck site to be found in the Florida Keys. This WWII ship was sunk in 1942 when it collided with another whip while dodging German U-boats near the coast of Florida. While the wreck is not intact (it was blown apart because it presented a boating hazard) it is home to a wide array of marine life. Scuba diving near the Benwood will bring you face to face with critters such as Pork fish, grunts, lobsters, moray eels, glassy sweepers, Sergeant Majors, Goatfish, and Christmas Tree Worms. Since the ship had run aground before it was blown up, the dive is a relatively shallow one and great for novice divers as well as advanced divers.

Cayman Salvage Master – This wreck that can be seen while scuba diving in the Florida Keys is a Cuban refugee vessel that was confiscated by the US government. The ship was tied up to a dock where she sank before she was re-floated. Then, during her burial voyage of 1985, she sank in about 90 feet of water coming to rest on her side. Recently, Hurricane Katrina righted the ship and now divers can swim along the hull and deck hoping to spy huge Jewfish and moray eels that reside in the open hatches of the wreck.

Duane – If you’re experienced at scuba diving, you might want to pay a visit to the wreck Duane while you’re in the Florida Keys area. This US Coast Guard Cutter was intentionally sunk in 120 feet of water in the year 1987. Due to the strong Gulf Stream current and depth associated with the wreck, only advanced divers are allowed to dive this site. The Duane is home to grunts, sponges, chubbs, jacks, barracuda, and numerous tropical fish.

In addition to these three wrecks that can be seen while scuba diving in the Florida Keys, there are several other wrecks in the area that have been intentionally sunk to become artificial reef habitats. Each offers a different experience and a unique look into how the ocean transforms a foreign object into a beautiful habitat where marine life can grow and thrive.

While Aruba may be better known for its beaches and casinos, it is also a good destination for the scuba diver. In fact, Aruba was voted the second best wreck diving in the Caribbean by Rodale’s Scuba Diving Magazine in 2006. So if you like wrecks, you may want to consider a trip to Aruba. Plus, you can always check out those casinos and beaches in-between dives!

Location

Aruba is situated 15 miles off the coast of Venezuela and is about a 2 1/2 hour flight from Miami. Given its popularity with tourists, this is an easy island to get to with many direct flights from the US.

Aruba, Bonaire and Curacao, all located off the coast of Venezuela, form the ABC islands. Aruba seceded from the Netherlands Antilles in 1986 and is now a separate, autonomous member of the Kingdom of the Netherlands.

Geography

Aruba is easy to explore at just 20 miles long and 6 miles wide. Like it’s sister island, Curacao, its landscape is dotted with divi divi trees and cacti.

The highest elevation on the island is Yamanota Hill at just 617 feet. It’s located near the center of the island and you can visit it by car. The northeast coast is rugged with cliffs and pounding surf.

The real draw here is the southwest coast and its beautiful beaches. Of the 3 ABC islands, Aruba has the best beaches. The most famous is arguably Palm Beach and Eagle Beach, which together stretch for seven miles. It’s home to the majority of hotels on the island. When you see its beautiful powdery white sand, you’ll know why. It’s also where you’ll leave from for most of your Aruba diving.

Reefs and Rides

Most of the dive sites in Aruba are best accessed by boat. The vast majority of Aruba scuba diving sites are along the southwest coast of the island. The reef is located on the south end with many of the wrecks on the north end. Boat rides from shore to the sites are normally less than 15 minutes.

If you are staying toward the middle of the island and want to dive the north end, you may want to (have to) take a short van ride to the boat. This is what we did when we were staying at the Tarmarijn and dove the Antilla and Pedernales wrecks.

Diving

The best Aruba diving is wreck diving. While there are walls and reefs, they are generally not as good as those on its sister islands. On many of the dives you can check out both a wreck and a reef for the best of both worlds.

Aruba is currently working to preserve its reefs and to maintain the quality of Aruba diving. Preservation and educational programs have been started, including a reef clean-up program. Dozens of mooring buoys have been installed to protect the reefs and a marine park has also been established.

If you go to Aruba, I hope you have fun exploring the wrecks galore. I know many people that have fallen in love with Aruba and, who knows, you just may be the next.

Have you done much cold-water wreck diving? If you’re used to Caribbean diving, this is a whole different experience. You’re going to want to get trained and certified for drysuit, and you’ll want to either buy one (check eBay), or find a shop that has one for rent in your size. You can try, but it’s really hard to rent a drysuit. If not integrated in your drysuit, you’ll also need a hood, gloves, and boots. If the conditions are just right, you might get away with a 7mm wetsuit on shallower dives, but when the water temps at depth get down into the 60s, 50s, and even 40s, you’ll be uncomfortable without a drysuit. You’ll need open-heel fins (slipper fins don’t work well with boots), main and backup lights, a tank light, and a wreck reel. Signaling devices are also a good idea, such as a safety sausage or a whistle. Many wreck divers carry a knife or shears, too, in case of entanglement. If you want to do more serious wreck penetrations, you should train for Wreck certification, too – you’ll live longer.

I’m not some serious, expert, North Atlantic wreck diver – I’ve only done two 2-tank excursions here in the NY Metro Area, and three dives one day in Lake Michigan (which is surprisingly similar), but I’ve logged over a third of my 91 dives at a cold local quarry called Dutch Springs, plus two at another quarry called Brownstone. I’ve also done the PADI advanced and Rescue courses, and completed the specialties to earn PADI’s Master SCUBA Diver certification, but I have no professional or technical training. I know I’m only a couple of North Atlantic wreck dives ahead of the rank beginners, but from my experience, I have two suggestions…

First, I’ve seen some rank beginner OW divers get into circumstances beyond their comfort level, and it makes for an unenjoyable (if not dangerous) situation for them. Education and experience will always be an advantage. Don’t stop at OW – take AOW certification – it’s not a terribly brilliant course of study, but it will give you experience in five different skill areas. U/Nav taught me to check my compass periodically, keep track of my surroundings and landmarks, and measure distance by time, air pressure, or fin kicks; until then, I always used to just blindly follow a dive master like a tour guide – it made me more self-reliant. Wreck taught me to lay and take up a line, ways to avoid stirring up silt, and to be aware of situational hazards. Drysuit and PPB taught me how to better control my buoyancy and trim. Night taught me to use lights and signals, and to be comfortable in low-visibility environments – it made me more confident. Deep, Multi-Level, Altitude, and Nitrox helped me understand more about the physiological effects of diving – awareness of my own body and mind help me prioritize and make better conscious choices, even while stressed, rather than let situations own me.

Most (albeit not all) instructors and many advanced students are also some very good divers, worthy of emulation. Spending more time training with them will improve your diving in ways beyond just the content of the training courses.

Second, take things one step at a time and don’t get in over your head. I had already completed Rescue certification, a bunch of the above-mentioned specialties, and 60-total dives, including many in the cold-waters of Dutch Springs and Brownstone before I ever went out on a North Atlantic wreck dive. Visibility was just past arm’s length and the water temps at depth were 59-degrees (in late July!). I’d gotten used to such temps at Dutch Springs, but add in low viz, chop, current, a touch of sea-sickness, and the lack of personal space on a “cattle” boat, and you’ll see how the stress and task-loading start piling on. Reflecting back on it afterward, I realized that there were a lot of mistakes my buddy and I made on that dive, despite all the training I’d had at that point. Everything turned out well, but tying our wreck reel to the anchor line was a classic newbie error, for example. My buddy was less-experienced, and was relying on me, to some degree, since I had some fraction of the requisite skills for the circumstances. If I had to advise anyone else getting into such diving, I’d say, take it one step at a time:

1. Get AOW and Drysuit certified
2. Get a drysuit and get used to it; practice the Drysuit controls, buoyancy, and trim in a pool
3. Practice more at a protected local quarry or lake
4. Practice more skills and/or earn specialties for Night, U/Navigation, Deep, and of course, Wreck
5. Practice night dives
6. Practice laying, following, and taking up line with a buddy; using a wreck reel is a skill all it’s own, and you can even practice it on the silly little wrecks at your local quarry or lake
7. Do some local night dives at your quarry or lake and try the line exercise again with a buddy – get capable of using a reel and lights at the same time
8. Once you’re good at it, look for some deeper wrecks; everything is more challenging when you’re cold and deep – once you’re comfortable with that, do it again on a night dive
9. Last, but not least, before you go on your first serious open-ocean cold-water wreck dive, I can’t overstate the value of Rescue training; don’t think of it as training to enable you to save lives – think of it as training to make yourself a better, more-aware diver. Before my Rescue class, I used to be just another tourist on a dive boat – now I get my gear squared-up early and I’m more aware of the divers around me. I can observe and help the less-experienced divers, and watch and learn from those more-experienced. An important lesson from the Rescue course is to foresee and avoid situations where rescue would become a necessity.

A shipwreck is a haven of wonderful discoveries for the scuba diver. It is a historical relic filled with secrets carefully concealed by the ocean. Over the years, it has also been the home of various sea creatures and plants. Wreck diving is a rare opportunity for scuba divers to hone their diving skills, discover a significant heritage in history and be a part of an important archaeological find. This great opportunity however entails responsibility on the part of the diver. So here are a few guidelines to take note of before pursuing the dive:

Precautionary Measures while Diving

• Remember that a shipwreck has been underwater for quite some time and the superior find have been submerged for decades, or even centuries. Many sections of a sunken ship may be fragile and would disintegrate without notice, so bear in mind to keep those fin movements steady and slow. The possibility of encountering marine animal and plant species inhabiting the wreckage is highly likely, so exercise extra care so as not to disrupt their habitat.
• There is also the risk of entanglement with fishing nets or ropes, so bring along an emergency tool such as a Tech Dive Knife in hand.
• Keep extra lights handy just in case primary sources of light run out.
• A guideline may also be utilized to ensure the exit route of the wreck diver.
• Never overestimate the capacity of your cylinder tank. It is best to be safe than sorry. The rule of the thumb is to allocate 2/3 of the air reserve for use upon exit. As much as possible, carry a second tank or bring along a pony bottle.

A Different Type of Training RequiredThere are wreck program organizations that require scuba divers to take a PADI specialty course in wreck diving before they can join excursions. The course will orient the scuba diver on the advanced skills and scuba equipment necessary to maneuver in and out of wrecks. More importantly, the scuba diver will be able to learn the proper management of air reserves in the course of diving. Deep diving is a specialization required in the conduct of wreck diving trips; thus the wreck diver must be knowledgeable on the use of dive tables as well. Dive tables reveal what depths (at certain times) are safe to cruise without decompression. An Aeris XR-2 Wrist Dive Computer [http://www.scubasuppliers.com/site/1408308/product/10.2610] is a convenient gadget that will come in handy to alert the diver of safety parameters.
