A flight instructor reported that a seaplane's horizontal stabilizer struck a dock after the water rudders were lowered during a departure in a right crosswind, with full left rudder ineffective.

Accident Sequence

The airplane was parked on the shore near a dock. The flight instructor (CFI) reported that after starting the engine, the airplane began to move forward. During this forward movement, the wing strut and wing cleared the dock safely. The instructor then began to lower the water rudders. As the water rudders were lowered, the tail of the airplane started moving towards the dock. A right crosswind was present during the departure. The instructor applied full left rudder with the water rudders partially extended, but this action was unable to stop the horizontal stabilizer from striking the dock.

Reported Conditions

The instructor reported that the right crosswind was a factor during the departure. The water rudders were partially extended at the time the rudder input was applied. Full left rudder deflection was attempted but did not prevent the horizontal stabilizer from contacting the dock.
