Massachusetts Environmental Police are investigating after the remnants of a vessel washed ashore this week that was believed to have broken loose from a mooring in Hyannis harbor.

Pieces of the vessel are now scattered on the beachfront between Bend in the Road Beach and the tip of East Chop, Massachusetts environmental police Sgt. Scott Opie said.

The vessel was originally a 43-foot wooden boat that had been stripped of an engine, fuel tank and other technology, Sergeant Opie told the Gazette late Wednesday. He said he had been in contact with the Hyannis man believed to be the owner, who apparently was in the process of refurbishing the boat when it broke loose in a gale.

“There’s little to show for it now,” Sergeant Opie said Wednesday, standing on State Beach as waves lapped over the submerged hull of the boat. “If you take a walk, you’ll see bits and pieces from here to East Chop.”

Tisbury, Oak Bluffs and Edgartown police are assisting with the investigation by locating debris. Sergeant Opie said planking from the boat washed up by the Oak Bluffs ferry terminal, and the bow turned up on East Chop, with smaller debris scattered in between.

To date there have been no citations, Sergeant Opie said, but he said the investigation remains ongoing. There is no plan yet for removing the remnants from the beach. In the interim, he advised caution to beach walkers.

“A lot of the debris is full of nails and screws,” he said. “Walkers and their dogs should definitely be aware of the potential puncture hazard.”
