Locking Headboard Assembly

Using the system
Headboard plate pivot pin lock -
The pivot pin locks to the car using two retractable spring plungers. Use a
small strap, zip tie
or line to get under and lift the arm. Rotate the arm to lock it out. The pivot pin can then be
removed.
Locking car at lock tracks -
Position sail at correct position so the pawls in the locking car are raised higher
than the pockets in the lock track. The proximity sensor and/or the mark on the halyard should be set to
indicate the proper correct position.
Pull trip line and ease halyard a small amount so the master pawl engages in the master pocket. Maximum
load on the trip line should be no more than 10 kg.
IMPORTANT! - Verify that pawls are engaged!
Release the trip line and carefully ease the halyard making sure the system is correctly locked.
Reduce the load on the halyard and put in about 300 mm (12") of slack in the halyard.
IMPORTANT! -
Providing slack to the halyard is important so the trip line is not accidentally tensioned. Damage to the
system can result, making it difficult to lower the sail.
The purpose of the slack is to compensate for tension on the halyard caused when the mast straightens when
sailing downwind especially on masts with a lot of prebend. This can raise the car a small amount and partially
disengage the pawls. Going through waves can further tension the halyard as the mast swings around a bit. If
the halyard tensions, the control link and pawl arms can deform causing the pawl to stick out a bit making it
difficult to release and lower the sail.
Locking car out of lock tracks -
Tension the halyard slightly and hoist a small amount. The pawls flip out of
the pocket and into the car. Ease the halyard slightly to check.

plunger on each side
