Dahlia wreck

A US-built minesweeper that burned in Saint-Pierre harbour

Area photo: Waielbi · CC BY-SA 3.0

The Dahlia was a US-built minesweeper, launched in 1942 and transferred to the French Navy, which used her for mine clearance and then stationed her in the Antilles. Sold in 1959 to a Saint-Pierre company, she caught fire in the harbour when workers converting her set her wooden hull alight with a blowtorch. Divers find her remains in 25 to 30 m of water.

Also known as Le Dahlia, Dahlia.

The dive

The minesweeper is explored between 25 and 30 m, deeper than the Diamant and shallower than the Biscaye. All three hulls fit into a single dive for divers in a hurry, but taking them two at a time leaves room to explore. Fixed life covers the wrecks and gives them an odd atmosphere that suits wide, moody photographs.
