Wreck Diving
Wreck diving is a type of scuba diving that involves exploring
wrecked ships. It is generally subdivided into three categories. A pass
over of the wreck is the simplest category. A diver doesn’t go
into the wreck itself in this kind of diving, but they must still be
aware of hazards associated with a sunken ship. There are animals that
like to make ships their home; and fishing nets or lines are often caught
by the wreck, making it easy for a diver to become tangled.
The second tier of wreck diving involves exploring the
light zone within a wreck. There is some penetration into the hull of
the ship itself, but generally a diver stays within the area they can
still see the sunlight. This ensures that if a diver’s equipment
fails, they can still safely exit the wreck and ascend to the surface.
Both light zone and pass over diving are considered recreational diving.
The final type of wreck diving is full exploration. In
this type, lights are brought along to explore the dark recesses of
a ship. This is a form of technical diving. Technical diving normally
has hazards associated with it that you won’t find in recreational
diving. The most common hazard is the inability to ascend directly to
the surface in the event of an emergency. In wreck diving, should an
equipment failure occur, a diver would first have to exit the wreck
before being able to leave the water.
