A 32-foot boat ran aground in the surf just west of Shinnecock Inlet on Saturday morning after experiencing mechanical failure.
Only one person was aboard the Trojan flybridge cruiser when it lost power west of the inlet, while en route to Hampton Bays from Freeport.
While the captain was trying to assess the issue, without having dropped anchor, the vessel drifted into the surf a few hundred yards west of the inlet.
The surf drove the vessel onto the sand, where it was flooded and battered by the breaking waves. The man who had been operating it was able to abandon ship onto the beach and was uninjured, Southampton Town Trustee President Scott Horowitz, who was present at the time, said.
Southampton Town Bay Constables and New York State Department of Environmental Conservation officers responded to the scene and found no signs of fuel spill, Horowitz said.
The boat was towed out of the surf later that day by a salvage crew from Suffolk County Parks Department.
