RedactedNarrative: V1 was adrift on Crab Island traveling south with the tide/current.  V2 was anchored on the south side of Crab Island.  V1 drifted near V2 and the operator of V1 engaged the motor into forward, instead of reverse, causing the bow of V1 to hit the starboard bow of V2. There were not any injuries sustained. They did advise they were adrift on Crab Island and came close to hitting a vessel but did not think they had hit it.  All three subjects on the vessel appeared impaired and could not keep their stories straight on how the accident occurred nor who was operating the vessel.  I was able to conclude they had lost their anchor which caused them to be adrift.  While adrift they came close to hitting V2 and had possibly hit it.
