Boat performance and trim during navigation
The boat is designed to accelerate rapidly, with a rapid stern-heavy hull
planing time.
To plane the boat easily and rapidly, just trim the stern engine by turning it
completely inwards. Indeed, when the boat is horizontal, the stern engine
should be trimmed slightly outwards to avoid an excessive draft which may
cause "bow steering" and excessive fuel consumption. In case of diagonal
waves, the turn could be sharper than expected.
Please also remember that a proper load distribution ensures a good trim
and, consequently, a good navigation performance.

STEERING
DANGER
An improper boat angle may cause "bow steering", which means that the
bow is too high. This condition is dangerous mainly when high waves are
taken over the bow and because of the instability entailed. The best
solution is to distribute the loads and to position the outboard engine
properly.
