SEARSPORT, Maine — A missing lobster boat worth about a quarter of a million dollars was found a day after it was reported stolen from the Searsport town dock.

The First Team, a speedy 36-foot-long black-and-white lobster boat that’s used both for commercial fishing and lobster boat racing, was spotted Friday evening by Sedgwick Harbormaster Bill Grant.

Sgt. Marlowe Sonksen of the Maine Marine Patrol said Tuesday the boat was found undamaged and is considered to have been stolen. The theft is still under investigation, he said. Father-and-son boat owners Keith and Travis Otis built the First Team at their Searsport business, Otis Enterprises Marine Corp. According to a website for First Team Charters, the diesel-powered boat was custom-built with a maximum speed of 38 miles per hour.

Efforts to contact the Otises Tuesday were unsuccessful.

The father and son are organizers for Maine Lobster Boat Racing, and the First Team earned the title of the world’s second-fastest lobster boat in 2004. It also has been a multiseason champion in its class.
