RedactedNarrative: The operator of vessel one was towed to the gas dock after running out of gas. After his vessel was fueled he started the engine and it was running at a fast idle. When the operator went to untie the vessel from the dock the gear shift was somehow moved into forward gear. When the vessel lurched forward the operator pulled the shift lever into reverse causing the vessel to lurch back into the two dock posts that the vessel was tied to and snapped. The vessel continued backwards hitting vessel two that was tied to a dock near by. This was witnessed by the gas attendant.  Damages to V2 and dock are unknown.
