Unit 1 was tied off and docked on the east side of the dock, with no passengers on board. 

Unit 2, with two passengers on board, was reversing into the landing area from the Cooper River in order to fight the current and weather to locate a useable docking area. 

A passenger on unit 2 stood up in order to jump off of the vessel on to the dock to assist unit 2, causing the captain of unit 2 to lose concentration of the changing winds and currents, and striking unit 1 on the starboard bow from the rear port gunwale of unit 2. Unit 1 had cracked and exposed fiberglass under the starboard bow rub rail, and unit 2 had epoxy damage and rub rail markings on the rear port gunwale.
