RedactedNarrative: On july 5, 2014 around 11:00am, operator and three other family members boarded their 36 foot sail boat which was affixed to the dock at slip of the new bern grand marina. Their intentions were to enjoy a four hour trip upon the neuse river. As operator was backing his vessel out of the slip in an eastern direction, he went to disengage the engine from reverse and reengage it into forward. The transmission then locked in reverse as operator made several attempts to change it into forward. The vessel then collided stern to stern with a 49 foot yacht attached to the dock. As a result of the collision, vessel2 sustained a two foot long crack on the port side of the stern about one foot above the water line, as well as buckling of the flooring of the deck nearest the stern. While the crew of operator's vessel was trying to hold themselves off from hitting any additional vessels, subject tripped and fell within the vessel resulting in a jammed right thumb, which she was transported to urgent care the following day.
