RedactedNarrative: At approximately 1218 hours on 5/7/16, Vessel 1 entered the bridge span of Las Olas Blvd. Bridge going approximately idle speed southbound on the Intracoastal Waterway in Fort Lauderdale, FL, Broward County, Florida. As the vessel entered the bridge span, the bridge spans began to close. The southern end (near the walkway for pedestrian traffic) of the bridge made contact with the mast of Vessel 1 causing it to bend and eventually break approximately 2 feet above the cabin falling on the port side of the vessel. After the contact, the bridge spans were then raised again. The vessel continued southbound under power until it anchored on the east side of the channel approximately 200 yards south of the bridge.  The bridge tender was at fault for closing before the vessel had cleared.
