RedactedNarrative: Vessel 1, a 78 ft Azimut, was entering Miami Bayside Marina while being operated by Operator 1. According to statements given by Operator 1, he was trying to enter Bayside Marina on one engine, as he had experienced an engine casualty earlier and decided to bring the vessel into the marina. Due to strong winds, the narrow entrance of Bayside Marina, and the engine casualty on the boat, Operator 1 lost control of the vessel and drifted into the Dodge Island Bridge with the starboard side of the vessel. While attempting to maneuver and regain control, the boat struck the City of Miami Fireboat (Vessel 2), which was docked at its slip, damaging and breaking the port side bow rail. The damaged sustained to the boat consisted of light fiberglass and gel coat damage to her starboard quarter and damage of an antennae array which was knocked off of its mount. After the collision, Operator 1 was able to regain control of his vessel and bring it into the marina without further incident. After interviewing witnesses, documenting damage to the vessels and speaking with the operator of the boat,  it was determined that the cause of the collision was due to Operator 1 deciding to bring the boat into the Bayside Marina, despite being aware of an engine casualty. The large size of the boat coupled with the narrow entrance of Bayside Marina and the high winds, made maneuverability difficult, with an engine casualty making safe entrance impossible. Operator 1 was cited for careless operation of a vessel resulting in an accident. All parties were provided with the relevant case information prior to clearing the scene.
