The by far best method is to stay the mast using
a forestay which extends though a smaller hole
in the deck (See fig. 3.5.b). Below two different
methods to decide the intersection point are
listed. For both methods, it is assumed that the
deck is of uniform thickness.
The bearing of the through-deck fitting has a
spherical surface which compensates for smaller
angle discrepancies between forestay and
through-deck fitting. However, it is important
to minimize the discrepancies to achieve maximum
furling performance the, angle between the
forestay and deck must be between 70,5° and 75,5°.
If the angle exceeds these limits, spacers must be
added between the through deck fitting and the
deck, so that the conditions are fullfilled.
