3 1/2 Fathoms Ledge (boat dive only)
This dive site, located outside of the Boston Harbor Islands, is loaded with beautiful walls, some that drop down to depths surpassing 80 feet. There are a bunch of crevices and cool swim throughs. Divers can come across stunning black sea raven, loads of sea stars, flounder, anemones, rock gunnels, lobsters, Jonah crabs, cunner, and nudibranchs.
Parking: Accessible by boat only
Levels: Intermediate
Max Depth at High Tide: 85 Feet
Ideal Wind Direction: Open ocean, n/a
Note the general area of Boston Harbor is heavy with boat traffic. We recommend using dive reels (especially if there is fog) to help guide divers back to the anchor line.
