V1 a 84' sailboat, with operator and occupants on board, was being towed by two Tow Boat US vessels. They were en-route to Palm Harbor Marina and V1 was not under power. While still under tow and attempting to dock the stern in the slip, V1 operator and occupants had a delay in untangling the dock lines.  Gusty winds blew V1 towards the dock. As the Tow Boat US operators began pulling  V1 out of the slip to attempt another re docking the operator of V1 started the engine and put the vessel in gear.  When V1 engine started it was at full power.  V1 continued across the fairway and collided with the dock and electrical box. The dock and electrical box were damaged.   Damage was observed to the starboard side bow and port side bow rail of V1. No injury's were reported.
