RedactedNarrative: V1 was operated by V1 Operator and attempting to dock at the courtesy dock located at the tiki bar restaurant on the south shore of Clear Lake Iowa.  As V1 attempted to pull into an available wet slip he did not make the turn and the front corner (starboard) of his pontoon (V1) made contact with another vessel (V2) already parked in an adjacent slip.  In an attempt to stop the collision Victim 1 from V1 reached out and broke her wrist/forearm.
