• CABLE ADJUSTMENT
Your mast will have been pre-set both by the boatyard and by the
mast manufacturer during the first mast stepping.
However,after a few sea trips,the mast should be reset once the ca-
bles have "given" to their full length.
proceed as follows:
- Slacken the lower shrouds.
- Tighten the topping lift or use the mainsail halyard in its place.
- Loosen the lazy-jacks.
- Take up the upper and lower diamonds,evenly in order to obtain a
straight profile. The mast should now curve evenly towards aft.
- The forestay is pre-adjusted to have an angle of 2,6° to aft.
- ension the backstays by tightening the turnbuckles with a wrench
and a 30 cm pipe (check that the mast head is centered).
- Take the tension back up in the lower shrouds by turning the tur-
nbuckles by hand.
- Take the lazy-jacks back up.
- The mast should remain curved towards aft.
LAGOON 421
Under sail with a 20 knot apparent cross wind,it is normal for the
leeward rigging to be slightly slack; if necessary,thread a shock cord
between the backstay and the lower shroud leeward to stop any
flapping .
• MAINTENANCE
Before each trip, carefully inspect the mast from top to bottom. Pe-
riodically check the rigging tightening and the lock nut or pin locking
(you should check it for the first time after a few days sailing in all
types of weather).
Secure and lubricate the bottle screws with tallow, graphite grease
or other (Never lubricate the bottle screws with silicone).
Check the bottle screw tightening.
Inspect the bottle screws for possible wear (due to the chainplate
friction if the rigging is slack).
Change any shroud or stay with severed wires or kinks.
Regularly check the chain-plates for wear.
DANGER
To hoist a crew member up to the top of the mast, make a
bowline with the halyard directly on the bosun's chair ring
(never use the halyard snap shackle or shackle).
Do not hoist a crew member when sailing in heavy weather.
ADVICE: Your LAGOON dealer can carry out all the maintenance
operations.
