Cape Ann, the Gloucester and Rockport headland northeast of Boston, has some of the best shore diving in New England: rocky reefs at 3–18 m (10–60 ft) off shore sites such as Folly Cove, Back Beach and Lanes Cove. Two Gloucester dive boats run to the seal colony at Dry Salvages and out to Stellwagen Bank National Marine Sanctuary, where the fishing-boat wrecks Patriot and Josephine Marie lie at 30–32 m (100–105 ft) in cold water.
About diving in Cape Ann & Stellwagen Bank
A diving day here is either a walk-in from a Cape Ann beach or a trip on one of two Gloucester boats. Numerous beaches in Gloucester and Rockport give easy shore entry onto rocky reefs, and Cressy Beach is protected enough to stay diveable in strong wind. Cape Ann Diver II runs from the rocky ledges off Cape Ann out to the wrecks of Stellwagen Bank, and Cape Ann Diving's Yankee Pearl cruises at 16 knots to the Patriot, the Salvages and the Isles of Shoals. Cape Ann Diver II generally runs from 1 April to 31 October.
The shore reefs are rock and typically lie at 3–18 m (10–60 ft). Folly Cove is prized for its diversity of marine life and bottom topography, and a surface swim to the left side of the cove reaches 18 m (60 ft). Lanes Cove has a wall that passes 18 m (60 ft) at high tide, where torpedo rays and goosefish are possible, and lobsters are abundant further out from the beach at Loblolly Cove in Rockport. Offshore, seals live on the rocks of Dry Salvages, boulder ledges shelter cusk and wolffish, and the Patriot wreck holds schools of pollock and other groundfish.
Stellwagen Bank National Marine Sanctuary lies offshore at the mouth of Massachusetts Bay, and Cape Ann Diver II runs to its wrecks. The water there rarely rises above 10 °C (50 °F), and currents can run strongly at the surface and on the bottom, especially when wind and tide move the same way. Gill nets are the greatest entanglement hazard, and one site sits inside Boston's shipping lanes. The sanctuary installs mooring buoys to spare dive sites anchor damage. Ashore, Folly Cove has no sand, and its slippery boulders make entry and exit awkward.
Cape Ann is used for training: Back Beach is a favourite for certification classes and Pebble Beach stays shallow. The Stellwagen wrecks lie at 30 m (100 ft) and more in cold water and current, some deeper sites need technical training, and Cathedral Rocks off Rockport is a site for the advanced. Winter and off-season diving does happen, but it depends on weather and demand.
