RedactedNarrative: Operator was operating a pontoon vessel bearing Florida registration. OP1 was disembarking from the dock located adjacent to the restaurant in Port Orange, FL. There were several other passengers on board. While OP1 was attempting to leave the dock, a gust of wind from an approaching thunderstorm caught their vessel, causing it to blow into a nearby docked Catamaran. The vessel that was struck was a 40-foot Catamaran sailing vessel. V1 struck the docked catamaran at approximately a 45-degree angle with the Port-side corner of the pontoon, resulting in a gouge in the rear starboard side of the docked catamaran. There were no injuries.
