Analysis

The instructor (CFI) elected to demonstrate a no-flap takeoff with calm/glassy water conds. After the float plane had accelerated to about 55 to 60 KTS without becoming airborne, he elected to abort the takeoff. He stated that he attempted a left turn & the float plane settled off step, but the forward momentum caused the acft to cont straight ahead. He called for 'rudders,' meaning water rudders, but the student reacted by assisting in applying normal rudder. The water rudder handle was located at the lower left corner of the instrument panel & was not accessible to the CFI, who was in the rgt seat. Subsequently, the float plane impacted an embankment with the eng shut down at an estd speed of 7 to 10 KTS. The CFI stated that he should have called for 'water rudders.'
