Why dive here
With 35+ marine species recorded in the area - including nurse sharks - Josephine Marie Wreck offers some of New England's richest wreck diving. Water ranges 4-19°C, warmest July, August, September.
The Josephine Marie isn't just another lump of metal on the seabed. For us, it’s a proper New England story, resting upright, a trawler from the 1960s that went down in 1992. When you drop down, the sheer scale hits you; it’s a big boat, sitting proud, and even in lower visibility, its silhouette is impressive. We love exploring the wheelhouse, still largely intact, which gives a real sense of its working life. Penetration is possible for trained wreck divers, but even staying outside, the stern and bow offer plenty to see. Look for the massive propeller, often covered in anemones and nudibranchs, our favourite macro subjects here. Lingcod often lurk in the deeper sections, and we’ve seen schools of pollock swirling above the deck like a silver cloud. Currents can be strong, especially on tide changes, so time your dive accordingly. We’d suggest a slack high tide for the calmest conditions. It’s a dive that rewards multiple visits; each time, you’ll pick out new details, another resident crab scuttling from a pipe, or a different bloom of jewel anenomes on the deck rails. It suits divers comfortable with colder water and who appreciate the history embedded in a wreck.
