V1 was being off loaded at Gandy Boat Ramp.  After being taken off the trailer V1 was listing to the starboard (right) side.  V1 then rolled to the starboard side, capsized and sank at the boat ramp.  Investigation later revealed that plug was installed and that there was a good possibility that there was a large amount of rain water in the bildge which caused it to list and eventually capsize.
