RedactedNarrative: Occupants of V1 stated they were swimming when the operator climbed back on board and noticed water coming into V1. They quickly got V1 to the nearest bank and tied it up. They were unsuccessful in attempting to pump out the water.  All stated they didn't remember hitting anything but did advise the previous owners had recently had some body work done on the vessel.  A towing company was contacted and when they pulled V1 away from the bank, it immediately sunk to the bottom.  They returned at a later date with air bags to retrieve V1.  They towed it to the nearest boat ramp and placed it on a trailer where a hole was discovered in the hull.
