Why Wreck Diving Is The Best

Wreck of the Zenobia in Larnaca CyprusImage via Wikipedia

Have you ever dreamed of floating silently through the oceans depths, exploring wrecks and maybe even discovering lost artifacts?

The ocean is a mighty beast and she has swallowed many unsuspecting ships and downed aircraft over the years.

There are many reasons that hobby divers take up this adventurous sport:

* wreck diving presents an exciting new challenge for even the most experienced diver. It is an opportunity to test your skills and expand your knowledge of diving.
* Many of the wrecks become artificial reefs and attract an abundance of sea creatures. You may see; crabs,lobsters,eels,beautiful reef fish.
* Many ship enthusiasts enjoy wreck diving because it gives them a chance to see some of the working machinery that would otherwise be out of view from the surface.
* People wreck dive because of the exciting and tragic historical interest surrounding many of the wrecks.

There are many organizations that offer training for new comers to wreck diving. SDI and PADI both offer such training.

It is always advisable to join a organized group excursion to some of thee dive sites as wreck diving carries slightly more risk than regular diving. Many of the wrecks are fragile and are covered in silt. If silt becomes disturbed due to fin strokes or other disturbances the, silt cloud created can cause zero visibility. This is where a lifeline comes in handy if you are planning on penetrating a wreck as it will guide you out when visibility is low.

As with all dives, it should be planned, you should always dive with a buddy and make others aware exactly where you plan to dive.

If you follow you training then wreck diving can be a fantastic experience.

Underwater Riches: Sunken Treasures Around The World

From http://www.history.navy.mil/photos/images...Image via Wikipedia

It would take over 400 years to excavate all of the wrecked ships currently unclaimed on the oceans floors. But just think of all the treasure you might find.

Flor de la Mar – Sumatra, Malaysia

Among the richest shipwrecks never recovered, the 16th Century Portuguese vessel, Flor De La Mar was lost around 1511 in a storm off the northern coast of Sumatra. Containing the stolen treasures of the Melaka kingdom in modern day Malaysia, the Flor de la Mar’s cargo, including 60 tons of gold remains undiscovered despite lying in some of the best diving waters of the world.

Merchant Royal – Dartmouth, UK

Britain’s largest unrecovered treasure haul lies just 21 miles (34 km) from Land’s End in Cornwall. The Merchant Royal, returning to England with a cargo of Spanish treasure sank in bad weather on 23 September 1641, containing 500 bars of gold, silver and precious stones. Bring a dry suit and a torch.

San Jose – Baru Peninsula, Colombia

In 1708, during the War of Spanish Succession, English Commodore, Charles Wagner captured and sank Spanish treasure ship, The San Jose in less than 1000 feet (305 metres) of crystal blue water, between the Isla del Tesoro (known as treasure island) and Baru Peninsula. The San Jose’s cargo is estimated today at a value of more than $1 billion.

Nuestra Senora de Atocha – Key West, Florida, USA


In 1985, Florida treasure hunter Mel Fischer hit the mother lode when, after 16 years of dedicated hunting, he located the wreck of the Nuestra Senora de Atocha about 35 miles (56 km) off the coast of Key West, Florida. Carrying a haul that included over 40 tonnes of silver and gold, 100,000 Spanish coins and Columbian emeralds, Fischer’s family now run diving holidays around the Atocha where artefacts continue to be uncovered.

HMS Victory – English Channel, UK


In 2009 US company Odyssey Marine Exploration announced that it had discovered the predecessor of Lord Nelson’s Victory, sunk in 1744, on a group of rocks known as The Casquets near to the Channel Islands. Thought to contain 100,000 gold coins, a legal row continues as to ownership of the haul.

Notre Dame de la Deliverance – Key West, Florida, USA


In November 1755 Spanish Galleon Notre Dame de la Deliverance left Havana with treasures collected from mines in Mexico, Peru and Colombia. A day later the ship was caught in a hurricane and sank with almost all hands, 40 miles from Florida’s Key West. Containing an estimated $2 billion in lost gold and silver, the site of the Deliverance was allegedly discovered in 2003 but has yet to be raised.

USS San Jacinto – Abacos, Bahamas

The waters off the island of Abacos in the Bahama’s combine some of the world’s best diving, plus an estimated 500 wrecks to discover and explore. Perhaps most interesting of the discovered wrecks in this area is the USS San Jacinto, an experimental civil war era gunship, among the first to be powered by steam, that sank off Chub Rocks in 1865.

Hoi An Junk – Da Nang Peninsula, Vietnam

During the 1990s a junk was discovered which sank in over 260 feet (79 metres) of water, 14 miles (22.5 km) from the Da Nang peninsula in Vietnam. Appearing to be of Thai origin, its spectacular cargo of blue and white and polychrome ceramics, painted with human figures, landscapes, fish, birds, and mythological animals, dates to Vietnam’s Golden Age of the mid-15th century.

Diving in helmet first . . . oops, helmet last

Football players wear them. So do people competing in hockey, baseball, cycling and a myriad of other sports.
But divers wearing helmets? And being supplied with compressed air via a hose at the water surface that connects to their helmets? Who would have thought it?
During a recent Caribbean cruise I experienced this interesting twist on underwater exploration during a stop at Coral World Ocean Park in St. Thomas in the U.S. Virgin Islands. It is called “helmet diving.”
We boarded a bus in St. Thomas and were taken on a 40-minute drive on the wrong side of the road – at least what North Americans consider the wrong side -- to our destination, which they called “the cove.” Among the other attractions at this facility are snorkelling, scuba diving and encounters with sea lions, sharks or turtles, to name a few. Equipment can be rented or purchased there.
The helmet diving base is a large round covered area. After a brief introduction that included instructions and the usual signing of a waiver absolving the facility of liability, gloves and water shoes were provided. We descended a ladder three steps into the water, where a white helmet was placed over our heads, resting on the shoulders. It was the receptacle for the compressed air that was pumped down from the surface.
The helmet, which featured a clear mask, was large enough to enable us to wear our glasses. That was a bonus in clear water where the visibility ranged from 30 to 40 feet. We were told to stay upright to prevent water from entering the helmet. Breathing was normal, but we had to purge our ears. The helmet weighed 70 pounds, but with the buoyancy created by the water we experienced a weight of just 15 pounds when we were below the surface.
Descending the final steps of the ladder to the ocean floor 20 feet beneath the surface in 81-degree Fahrenheit (27.2 Celsius) water, we began our helmet dive walk. Two scuba divers guided us on the 30-minute trip. An added safety measure was a chain along the route; we were told to hang on to because the water was fast moving. Unfortunately, one of our helmet divers had to leave the water after experiencing breathing difficulty. While it should not be a problem for most people, those who have breathing difficulties or who suffer from claustrophobia might not want to try it.
Of the five of us taking part in the helmet dive, I was the only one who scuba dives. It struck me that helmet diving is an excellent opportunity for those who do not wish to go the scuba route to see some of the underwater world that thrills divers. But in exposing helmet divers to that same visual experience – especially in the clear waters of the Caribbean – it is also a vehicle to attract new people to scuba.
I would highly recommend helmet diving to anyone thinking of getting into scuba diving, or to those who just want a glimpse into a diver`s world.
