RedactedNarrative: V1 had some mechanical repair work done over the last several days at Palm Harbor Marina, Palm Beach. The captain/operator took V1 out for a test run and had problems with the steering.  The bow/pulpit of V1 struck the starboard side of V2 causing a hole in V2.  V2 was docked at the time of the collision.  No injuries occurred. V1 also caused damage to the dock at the Marina. V1 called JAS Marine service and mechanic  whom responded to the location.  His inspection of V1, determined the port transmission solenoids were reversed.  He, then, corrected the problem. The written statement given by him explained that when V1 shifted into reverse, the vessel actually moved in a forward action and vice versa
