Operator #1 stated: I was pulling up to the dock to refuel when the throttle got stuck and wouldn't go into reverse. I pushed the throttle forward a bit, then tried to reverse again and it was still stuck.  I tried it a third time, and the boat jumped forward and I hit the other boat. Then I crashed into two Pilings.

Investigation revealed: Vessel #1 was facing south attempting to dock and refuel, while vessel #2 was moored at the dock facing North, when they struck.  As operator #1 slowed, he attempted to place the vessel in reverse, however he was unable to do so, due to an unknown mechanical failure. Operator #1 tried to maneuver the vessel by continuing forward. While traversing forward, vessel #1 came up on plain, and struck the port bow of vessel #2, with it's port gunwale. Vessel #1 then continued forward in between vessel #2 and a Piling, then struck the piling with the starboard gunwale.  Vessel #1 continued further south and struck a second piling, with the bow Gunwale, breaking the piling in half. The piling then struck vessel #2 and broke a port side window. Vessel #1 then came to rest in the adjacen slip.
