Sunapee Police Department is asking for help in solving the mystery of the sinking boats. Chief David Cahill says two older wooden boats like the type used in the boat parade sunk while in their boat house during the past two weeks. Cahill says one boat had the plug pulled from it and it was definitely an act of vandalism. The second boat sunk four days later, though the plug was not removed. Sunapee Police are actively investigating the case have asked residents along the lake front and on the island if they saw anything suspicious. The boats have been recovered from the waters and one is repaired and back on the lake. Anyone with information on either of the sinking boats is urged to call the Sunapee Police Department at 603-763-5555.
