The "Southwest Mohawk" or "Coffee Wreck" is nothing like its namesake. Artifacts found on the wreck indicated that it was a late eighteenth-century sailing ship and not a barge.
The "Three Sisters", as she is called, is an unidentified wooden-hulled vessel. She sits in 80 ft of water some 13 miles south of Atlantic Beach Inlet. She sits on a sandy bottom, spread out over a small area. Her boiler and a 4 bladed propeller are still visible. Wooden beams and planking spread out from the boilers aft towards the propeller. Occasionally some artifacts are found, mostly brass fittings. This is generally a decent wreck for lobsters and spearfishing. This wreck is in a main shipping channel, and large vessels make large wakes, so secure all gear.
A typical smallish schooner barge wreck of unknown origin. Some anchor chain and decking spread out over a small area, with a few smaller pieces way off the main piece. Named after the fishing boat that found the spot.
