Probable cause
The pilot's encounter with unsuitable terrain (rough water) and his inability to maintain directional control.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
While executing touch and go water landings the aircraft experienced a loss of control when it encountered boat wake. The aircraft was spun around and during this maneuver sustained substantial damage.
