RedactedNarrative: On May 31st, 2019 at approximately 1755 hours, a 2003 52’ Ocean Yacht bearing documentation number DO1147603 was on the Ocean side of Snake Creek drawbridge waiting for the bridge to open in order to cross to the bayside of Snake Creek. At approximately 1557 the operator of the vessel hailed the draw bridge operator over VHF radio in order to find out when the bridge was going to open. The bridge operator informed him that the bridge would open in approximately three minutes at 1800 hours. Operator was intermediately engaging the throttles in reverse to maintain position on the bayside of Snake Creek bridge against the Northbound current. At some point before the bridge was able to open, the 52’ Ocean Yacht operated by Operator lost all mechanical power and steering. Operator hailed a Mayday call on VHF channel 16 indicating that he had lost all power and steering and was drifting towards the drawbridge. The Northbound current traveling at approximately 2-3 knots carried the 52’ Ocean Yacht approximately 50 yards towards the drawbridge causing the vessels tower to strike the bridge. The top of the tower was left behind attached to the center of the drawbridge. The vessel continued on, passing under the drawbridge where a United States Coast Guard small vessel took the 52’ Ocean Yacht under tow. The Vessel was then turned over to a towing company to be towed into Plantation Yacht Harbor Marina.
