RedactedNarrative: OWNER PUT VESSEL INTO THE WATER OFF THE TRAILER AT KATHERINES LANDING BOAT RAMP. HIS FRIEND BACKED THE VESSEL UP WHEN IT STALLED. HE STARTED TO DRIFT AND COULD NOT GET THE VESSEL RESTARTED. THE FRIEND AND SOME BYSTANDERS PUSHED THE VESSEL TO A BOAT SLIP. THE OWNER WAS WALKING BACK FROM DROPPING THE TRUCK/TRAILER OFF IN THE PARKING LOT WHEN HE NOTICED IT STARTING TO SINK. BY THE TIME HE GOT TO THE VESSEL IT WAS HALF WAY SUNK IN THE WATER IN THE SLIP. THE BOW OF THE VESSEL WAS STICKING OUT OF THE WATER IN THE BOAT SLIP WHEN I ARRIVED. TOWBOAT USA WAS CALLED TO BRING IT UP.
