Page 25: Raise Sail
WARNING! Sail can become uncontrollable when raising in windy conditions, resulting in loss of footing. Choose wind conditions to match your experience and ability.

Page 27: Operation Check Halyards
They permit a very tight headstay to be eased when boat is not in use. For best performance, consider adding a backstay adjuster: either a block and tackle, a mechanical adjuster, or hydraulic adjuster like those offered by Harken. Remember to keep headstay tight for best performance when furling or reefing. -

Uncleat furling line. Pull sheets to unfurl sail. IMPORTANT! Keep tension on furling line when unrolling sail so line spools tightly on drum. Use a Harken ratchet block or keep tension on the line by putting a single wrap of the furling line around a spare winch to provide drag on the line. This is very important when wind is blowing over 10 knots. -
Page 29: Secure Sail
Operation Reef/Secure Sail Reef A sail may be partially furled before you resume sailing. This is known as reefing. Tip: Place marks on foot of sail for a variety of reefed jib sizes. Place marks on jib lead track so lead block position matches reefed jib. -
Page 30: Adjust Turnbuckle
To use a halyard to hold foils lifted, tie a rolling hitch to the foils using another line or use the actual halyard if suitable. See www.harken.com/knots for tying resources. CAUTION! Foils have considerable weight and can drop and cut hands if placed underneath. -
