RedactedNarrative: Unit 1 was entering the Marina and failed to account for wind and current.  The operator of Unit 1 failed to compensate for the elements and failed to maintain control of the vessel while attempting to enter the Marina. Unit 1 began drifting towards Unit 2 and Unit 3 which resulted in the aft starboard rub rail of Unit 1 striking the aft starboard quarter of Unit 2, causing minor damage. Unit 1 continued drifting and the aft starboard rub rail also struck the starboard side of Unit 3 twice before the operator of Unit 1 regained control of the vessel. This second event caused moderate fiberglass damage to the starboard side of Unit 3 in two locations. There were no reported injuries.
