The Raisiniers Wreck
An upturned barge, turned into shelter
Town : Saint-Pierre
The Raisiniers is a transport barge lying upside down on the bottom. It is a site we often pair with the Babodie Canyons in the same day.
An upturned hull is a roof
The right way up, a barge offers a flat deck and little interest. Upturned, it becomes something else: the hull forms a ceiling, and the space beneath becomes an artificial cave.
That is exactly what marine life looks for. Shade, shelter from the current and protection from predators all come together there, and the density of life under the hull is nothing like that of the surroundings.
What a wreck becomes with time
A submerged structure is first covered by a bacterial film, then algae, then fixed organisms: sponges, hydroids, soft corals. Fish follow, the small ones first, then their predators.
Within a few years a metal object becomes a reef in its own right. That is what is called an artificial reef, and a sunken barge ends up sheltering more life than the sandy bottom around it.
What level you need here
| Your level | What you can do here |
|---|---|
| Level 1 | The outside of the barge, depending on the depth on the day |
| Level 2 and above | The whole site |
Under a hull you never commit without a way out in sight. Stay at the edge, where daylight comes in: that is where the life is densest anyway.
