RedactedNarrative: On June 24, 2017, at approximately 2227 hours, vessel #1 (V#1) bearing FL 7683 PT was attempting to dock at Sunset Harbour Yacht Club. As V#1 was approaching the dock/slip, the captain went to engage the bow thrusters but experienced a mechanical failure. Due to the bow thruster's mechanical failure and wind conditions, V#1's port stern collided with vessel #2's (V#2) starboard bow and vessel #3's (V#3) pulpit.
