V1 was facing south in harbor town marina attempting to back north into slip 12. As v1 began backing north the operator of v1 was unable to get the bow and stern thruster to function properly. During this time the wind speed was a moderate 7 to 14 mph coming from the east, southeast which was causing v1 to drift towards the other docked vessels. As the operator was attempting to maneuver v1 against the wind and without the use of functioning thrusters, the bow railing on v1 made contact with the bow railing on v2 docked in slip 19. The bow railing on v2 was bent and the gel coat was damaged around the rail stantions. while v1 was continuing to maneuver out of the situation the bow railing of v1 then struck the bow railing on v3 docked in slip 18, causing it to bend off center. V1 continued backing north towards slip 12 when the bow railing of v1 struck the bow railing of v4 causing the railing to bend and crack the gel coat. V2, 3 and 4 were backed in to their assigned slips unoccupied and properly docked. Due to the size of v1, wind conditions and malfunctioning thrusters, the operator stated he was unable to avoid contact with other vessels. There were no injuries as a result of the accident and no citations were issued.
