Go to end, this is Mag. 127N. Stay on 127 approx. Plum is across from baseball field. Okay till 11am after that resident only. Sandy easy entry, shallow cove, reef outside cove on right.
Kids love the tide pools.
Get a chart, as much of it is submerged. Bow of tanker, in 60' - 70' of water, broken up. Sunk in 1957. Just Northeast of Thacher Island off Rockport. Upright, intact, and really awesome dive.
