La Dieppoise - Prony Bay
La Dieppoise isn’t just a wreck; it’s a time capsule, a jagged steel skeleton that brings history to life right before your eyes. We love diving it early in the morning, before the day boats arrive, when the light penetrates the superstructure just so. You descend onto the deck, and the sheer scale of the ship hits you, its bow pointing towards the surface, its stern settled deep into the sand. As you navigate the holds, now open to the sea, schools of fusiliers swirl inside like living curtains, while lionfish perch, almost posing, on corroded beams. The wheelhouse is our favourite part; swimming through it, you can almost feel the presence of the crew. Look closely at the deck plating, where we've spotted nudibranchs in colours so bright they practically glow. This site is a photographer’s dream and perfect for divers who appreciate the blend of history and thriving reef life. Just watch for the surge if there's any swell running; it can make navigating the deeper sections a bit of a workout.
