A sailboat left un-piloted for a "period of time" Sunday morning collided with an anchored boat in which occupants were fishing off the Darien coast, according to Darien Police, causing severe injuries to one of the fishermen.

At about 9:45 a.m., Darien Police report a collision occurred between two boats approximately one mile west of Green's Ledge Lighthouse on the Long Island Sound. A 33-foot sailboat was operating under power when the operator, one of three people on board, went below deck to retrieve an item leaving the sailboat un-piloted. During that time, the sailboat hit the center console of the 20-foot boat, which was anchored at the time, on the right rear side. The impact forced the rear of the boat under water momentarily. One of the occupants fishing was seated at the rear of the baot, and was struck by the sailboat, suffering "fairly sever injuries to his right leg," according to a release from Darien Police.

"Both boats were able to get into 5 Mile River to secure their vessels and seek medical treatment for the injured parties," Darien Police said.

The Darien Police Marine Division, the Norwalk Police Marine Division, and the United States Coast Guard- Station Eaton’s Neck all responded to the incident. The boating occupant injured was transported to Norwalk Hospital for treatment.

Both the Darien Police and USCG are conducting parallel investigations. The operator of the sailboat was cited by the USCG for “negligent operations” under the United States Code. Investigation is ongoing, Darien Police said. 

The Darien Police Marine Division added that it stresses the importance of having working VHF radios aboard, and being knowledgeable in their operation in the event of an emergency. When serious injuries occur on the water, a working VHF radio can save valuable time in seeking assistance as you can communicate directly with public safety vessels. The Darien Police Marine Division can be reached using VHS hailing/distress channel #16, as can the USCG and most other public safety agencies.
