Twist
The twist describes the course of the leech of a sail. The Twist has a huge impact on the sai-
ling qualities of your Mico Magic. With zero twist (just stretched leech), you can bring your
boat to stand the wind on the spot, which is certainly not desirable. Basically, you go with
stronger wind a little more twist (more curvature in the leech) than in low wind. Stronger wa-
ves also require a little more twist than a smooth surface. Unilateral adjustment of twist on a
sail can influence sail properties similar as the opening angle. The twist of the jib increases
by tightening (shortening) of the forestay. The twist of the mainsail is set by turning of the
pressing. A starboarding boot can be set neutral with a little more twist in the mainsail,
without changing other control variables.
Base settings
During assembly of the boat you have already taken the essential settings. The mast is tilted
all the back.
If you drive a mainsail without luff curve, the mast is not bent. Otherwise, make a slight bend
an aft. The deflection of main sail forestay should still easily extend into the mast.
Stretch a little the forestay. From just not hanging about again half the length of the clip pus-
her. More information about the tension of the forestay can be found under the heading Main
sail tension and in the “stronger wind“ section.
Pull the foresail of both sails straight without applying a lot of tension.
The jib has about 17mm tread depth, the main about 20mm.
By sailing the jib boom is at a point close to the middle between the mast and deck edge. The
extension of the boom is about in the middle of the sloping cockpit rim.
The twist in the main (sagging against backstay, by mast in the middle) is about 35mm, the
jib has about 25 mm Twist (sagging against forestay). Both can determine the inclined on the
side of boat in a windless place.
This is the setting of your boat in constant 1 to 2 Bft. Sailing close to the wind, without having
a clear tendency to luff or falling. Before making changes to the trim, check first whether the
boat, on both sides on starboard tack (wind coming from starboard) and on port, has the sa-
me sail performance and adjust if necessary after the center position of the rudder.
The boat can naturally be driven with different settings of the mast and sails. But even top
sailors drive their Micro Magic approximately with the described basic trim. You should not
deviate too far from the recommended set values, without having acquired further knowledge
just at the beginning. If you are traveling at close-hauled the boat sails significantly denser
than described in conjunction with the relatively full sail profile of the basic setting, no higher
sideways drift on the wind or go faster, but with more heel because of the angle of attack of
the sail does not fit.
The adjustments to the trim described below are carried out in the millimeter range and can
have a significant impact yet.
