Vessel 2 was docked at the Jacksonville Landing with bow facing towards south in St. Johns River.  Vessel 1's operator was attempting to raft up to another boat.  Vessel 1's operator stepped off the boat onto another boat and lost control of his boat.  Vessel 2's occupant took control of vessel which was drifting in swift current.  While traveling east attempting to gain control operator of Vessel 1 clipped the port-side of Vessel 2 multiple times with it's rear starboard side.  Protruding rub-rail on Vessel 1 caused cuts in the side of Vessel 2 and caused a dent in the frame of the port hole..
