UNSTEPPING THE MAST
- Mark the rope locations with stickers.
- Proceed in reverse order compared with the mast installation.
CABLE ADJUSTMENT
A professional carried out the pre-adjustment and the cable tightening.
After a few sea trips, adjust the mast definitively to get a perfect widthwise rectitude of the mast.
To keep the mast straight lengthwise when sailing get a balanced adjustment when in port:
- Classical mast:
• Slightly pre-bend the mast lengthwise, the middle of the mast bending forwards and the head
backwards.
• The pole shall be about half the section of the profile.
- In-mast roller furler:
• Pre-bend the mast lengthwise very slightly.
• The pole shall be smaller than the half of the profile section.
BALANCE ADJUSTMENTS IN PORT
- Before you fasten the backstay, tighten the upper shrouds (because the boat is rigged with swept
back spreaders).
- Tighten hard the whole rigging (when sailing with 15 to 20 knots, the leeward rigging is slightly
slack and it is normal).
- After getting a perfect widthwise and lengthwise rectitude when in port, symmetrically slacken the
aft lower shrouds (on portside and starboard) by 2 bottle screw turns.
- To end the lengthwise adjustment, tighten hard the backstay bottle screws till you get a fair stability
of the forestay when sailing with a wind at 15 to 20 knots.
Keep all the bottle screws adjusted and use the pins. Keep the adjustment throughout your sailing
season.
ADVICE: The forward lower shrouds serve only to keep the mast lengthwise. The lower
shrouds shall not be taut excessively.
