turns, the changing water flow under
the vessel will cause the pitch and
roll attitude of the vessel to change
while the boat is in a turn. As soon as
the vessel exits the turn, the boat's
attitude will return to normal. Turns
during operation of a boat are a very
temporary condition. For this reason
the ATP controller will sense that the
boat is in a turn and modify the way
that it tries to adjust. If the turn is
fairly gradual (less than 1 degree per
second) the ATP control will still
make adjustments to the boat to
compensate for pitch changes. These
pitch changes are uniform on both

Planing
After a turn the ATP control will wait
four seconds to allow the vessel to
settle before attempting to begin
automatic control again.

the trim tabs to a full-up position as

senses the deceleration and puts the
