Adjusting boat trim
When the boat is on plane, a bow-up attitude
results in less drag,  greater stability and effi-
ciency. This is generally when the keel line of
the boat is up about 3 to 5 degrees. With the
bow up, the boat may have a greater tenden-
cy to steer to one side or the other. Compen-
sate for  this as  you steer.  The trim tab  can
also  be  adjusted  to help  offset  this  effect.
When the bow of the boat is down, it is easier
to accelerate from a standing start onto plane.
Bow Down
Too much  trim-in causes  the boat  to plow
through the water,  decreasing fuel economy
and making it hard to increase speed. Operat-
ing  with excessive  trim-in at  higher  speeds
also makes the boat unstable.  Resistance at
the bow is greatly increased, heightening the
danger of bow  steeringand making opera-
tion difficult and dangerous.
