To hoist the sail see the description in chap. 11.1.

Attach the head of the sail directly to the halyard swivel.

Tack the sail at deck level with a piece of rope between the sail tack and the tack snap shackle on

the lower bearing assembly.
Hoist the sail (See chap. 11.1, ”To hoist the sail”). Adjust the rope length at the tack so that the

halyard swivel attains its top position, i.e. the 5-10° requirement is satisfied, when the halyard is

fully tensioned.
There should never be less than 20 mm (3/4”) clearance between the top of the halyard swivel and

the top guard when the sail is fully tensioned.

7. All the boat’s foresails must be adjusted to the correct luff length.

For the halyard routing to work properly, the halyard swivel must be in the correct

position to achieve the required angle of 5 - 10°.

Fig. 7.3.a

Fig. 7.3.b

min. 20 mm (3/4”)

Measure the length of the rope while the

halyard is still tensioned.

Attach a wire pendant corresponding to the

length of the rope directly to the head of the

sail by a talurit splice. This cannot then be

removed unintentionally, lost or exchanged.

Smaller foresails such a cruising (working) jib will have a higher clew, giving better visibility under

the sail, easier passage over the guard rail and less exposure to waves breaking over the foredeck in

heavy weather. This type of sail often requires less adjustment of the sheeting position when reefed

(See chap. 12,

Reefing

A furling genoa is usually a compromise between optimum performance and a more practical sail. The

sail is designed for both light and strong winds, and is cut with less draft, giving it a flatter shape when

reefed.

Several methods have been developed to improve the shape of a reefed sail. Many sailmakers use

”foam” as a filling material along the luff of the sail. The foam is tailored to match the sail cut, and

increases the diameter of the sail roll when reefing. A larger diameter of the sail roll gathers in more

sailcloth per turn and the draft is reduced by varying amounts along the luff extrusion.

Together with the ”free turn” (See chap. 12,

Reefing

) and the design of the Furlex luff extrusions, this

can give the best reefed sail shape.
