Important information for both installers and owners.
•
Do not raise the boom with the topping lift or vang more
than 3 feet from the normal operating angle, as the mandrel
will bottom out on the boom end plate and cause damage. If
it is essential to do this, the mandrel must be disconnected
from the universal.
•
If the boom is dropped down to the deck for any reason en-
sure that the mandrel has not dropped off the aft end spigot
before raising the boom again with the vang or topping lift.
•
If it is necessary to furl downwind pull the boom in to 45
degrees before commencement. This decreases the load in
the sail, gets the sail off the shrouds and spreaders and in-
creases the efficiency of the universal.
•
Ensure that the end float between the universal inner face
and the inner bearing casting is no more than 1/16".
•
If a topping lift only is being used to support the boom, tie a
knot in the topping lift line aft of the rope clutch or cleat to
ensure that if someone accidentally releases the topping lift
cleat the boom doesn’t crash down and cause damage or
hurt someone.
•
Ensure all track joints are smooth and radiused. The track
entrance from the sail feeder is particularly important.
See diagram 5.
•
Ensure that there is nothing on the mast in the area that the
sail rolls that could possibly cause sail chafe. This could
include fittings around the side of the mast and trisail tracks.
