The boat left Hancock Pt. about 2pm on Thursday afternoon with 6 people aboard to go clamming on Stave Island. They clammed that tide and started from Stave Island back to Hancock Pt. with 12 bushels of clams and 6 people. Apparently the motor got snarled up in a rope from an old lobster trap and stopped. The wake of the boat came over the stern of the boat and filled it causing the boat to upset throwing all of the people into the ocean.
