8. Fit the through deck fitting. The markings (A), fore and aft of the fitting,
will help to center the fitting in the longitudinal direction. The deck fitting
has a compartment for sealing compound which can be used if required.
Check that the through deck fitting rests against the aft edge of the hole when
the the screws are tightened.
If the deck thickness admits, an additional screw can be fitted as per B.
If the deck is thin it can be necessary to increase its thickness locally for
the screws to sit firmly.

3.2 Fitting of the lower bearing assembly to the boat.
1. Measure the distance between the upper edge of the through deck collar and down to the hole of the chain
plate in the bow. Unscrew the fork terminal so that measurement (X) corresponds to this measu
~10mm. Unscrew and back off the nut (A) so that there is ~15mm between the nut and the face of the shaft.
2. Remove the clevis pin (B) and lower the bearing assembly through the deck collar. Attach the fork to the
chain plate. Fit the clevis pin but do not secure it with the split pin yet. Adjust the length of the bearing assem-
bly by turning the toggle (C). Adjust until the lower edge of the tack ring is about 4-5 mm from the throughdeck
collar. Lift the tack shackle upwards and rotate the tack ring. Check that the tack ring does not touch the
through deck collar at any point. The tack ring will tilt a little when under load which is normal.
3. Remove the clevis pin and lift up the lower bearing assembly. For electric systems this concludes the adjust-
ment, do not tighten the nut (A) . For manual systems continue as follows: Unscrew the fork terminal at least 5
turns, Note! count the turns. Apply a bead of locking adhesive to the thread (D) and screw the terminal back to
its original position (counting the turns). Tighten the locking nut firmly while clamping the toggle in a vise if
possible, or locking it with a screw driver or similar (E). This is a permanent setting of the length of the lower
bearing assembly, ensure the nut is tight.
Lower the bearing assembly through the deck fitting again. Fit the clevis pin and the split pin connecting the
fork to the chain plate. Lift the tack shackle upwards and rotate the tack ring ensuring the gap to the through
deck collar is still satisfactory.
Never adjust the swivel length with the forestay attached.
