A new marine patrol vessel, which will be used to patrol Lake Mahopac, has been launched by the Putnam County Sheriff's office. The new vessel replaces a 1998 Boston Whaler.  Sheriff Robert Langley says it comes equipped with Radar and a Forward Looking Infrared Camera.  It was provided to the Sheriff’s Department by the New York State Department of Parks, Recreation and Historic Preservation, at no cost to Putnam County.
