engine should be in before throttling up from a dead stop. Negative trim exerts downward force on the hull
to reduce bow rise that is common to most planning hulls under initial acceleration. The harder the initial
acceleration, the greater the tendency the bow will rise. If you throttle up hard from a dead stop, (a
procedure called "hole shot") some hulls will lift the bow at a severe angle momentarily until the downward
force of the engine counters the rise.
(5) Outboard trim angle can be adjusted to improve planning and general performance. Adjust the position of
the trim rod of your motor to define the trim angle of the outboard motor in relation to the transom. Make
test runs with the trim set to different angles to find the position that works best for your boat and operating
condition.
3. Towing
Your boat can be towed using the towing eye located at the bow. Make sure to use a tow line that is rated at
least 5 times the weight of the boat being towed. The boat should only be towed using the towing eye. Molded
handles, lifelines and cleats are not designed to be used for towing.
a) It is recommended that the boat be towed with a bridle arrangement using the D rings on the either side of
the bow.
b) An extra safety line should also be attached to the welded-on aluminum eye under the bow of the hull.
c) Please note that towed dinghies need to be constantly monitored and especially at night.
d) When a dinghy is towed, the conditions may vary quite dramatically so the responsibility for its security rests
entirely with the skipper.
