RedactedNarrative: V1 WAS SOUTHBOUND IN THE ICW DURING THE FORT LAUDERDALE INTERNATIONAL BOAT SHOW. DURING THE SHOW THE ICW IS VERY RESTRICTED IN ITS WIDTH. V1 WAS PASSING CHANNEL MARKER 12 WITH A VERY STRONG OUT BOUND TIDE BEHIND HIM. V1 SWERVED TO AVOID THE CHANNEL MARKER BUT STRUCK IT ON HIS STARBOARD SIDE, PULLING THE DAY BOARD OFF THE CHANNEL MARKER. THE DAY BOARD WAS RECOVERED AND GIVEN TO THE USCG.
