Wider pocket
General description - Locking mechanism - Locking headboard system consists of locking car, lock track and
headboard plate. The car has multiple pawls that lock into pockets in the lock track. Return springs keep the pawls
retracted into the car for hoisting and lowering. Once the sail is hoisted to the correct height, pulling the trip line
moves the control link, leveraging the pawls' control arms simultaneously engaging the pawls into the lock track
pockets. Easing the halyard seats the pawls and the halyard and trip line can completely ease. Halyard should be
eased when car is locked.
The master pawl and corresponding pocket are wider than the slave pawls. Because all pawls are connected by the
control link they cannot engage into the sockets until the master pawl engages in the wider pocket.
The weight of the sail keeps the pawls engaged, so trip line and halyard can ease. When the halyard is tensioned
the return springs push on the pawl triggers to retract the pawl into the car.

Locking Headboard Assembly 3
General description - Locking mechanism continued - The trip line connects to plungers that compress springs
when the trip line is pulled. The energized springs operate the control link. Once the sail is hoisted so the pawls
are just above the pockets, the locking procedure starts. When pulling the trip line and lowering the sail, the
energized control link levers the pawls to find the pockets. Continuing to lower the car engages the pockets.
Installation, Proximity sensor The locking
car has provisions in the slider bearings for
a magnet so that proximity sensors can be
used at full hoist and at the locking car reef
locations. Any of the slider bearings can
house the magnet allowing for flexibility of the
sensor mount location. A light press-fit holds
the magnet in place. Use a block of wood
and mallet to tap the magnet in place. In use,
a light indicates that the sail height is in the
correct position with locking car pawls raised
higher than the lock track pockets. Pulling
the trip line while the car is lowered energizes
the pawls to engage into the locked position.
Alternatively use marks on the halyard.
Note: The sensor magnet is supplied by
Harken. The proximity sensor is not supplied.

Installation - Trip line
1. Trip line runs in sleeve in the sail luff. Choose Dyneema®uncovered 12 strand core for the trip line so that is
slides easily in the sleeve.
2. In the lower portion, just above the reef tack fittings, provide 1 to 1 1/2 m (3' to 5') gaps in the sleeve for access
to the trip line. A leader line can splice to the trip line and exit out the sleeve gaps just above each reef tack location.
This allows the tensioning above the reefed sail folds.
3. Secure the top end to the headboard car trip line bridle. Use a shock cord between the spectra line and the
headboard plate to reduce unintended tensioning of the trip line. Test to make sure the trip line can overcome the
shock cord to engage the pawls.

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

Maintenance
Servicing slider mechanism
Occasionally the slider bearings on either end
of the car may need replacing. To remove a
slider, use a large zip tie or similar plastic item
to pry the slide away so it can slip off the car
end. Slider bearings have a raised boss that
mates with the recess in the car. See image
below.

Troubleshooting
Locking car will not release -
Make sure:
1. Trip line is eased. Make sure it is not caught on anything.
2. Halyard is tensioned to counter the weight of the sail.
If the tip line does not have tension and pawls will not release, remove four screws securing trigger body to
the car. Lift the trigger body so the pawls can release.
Car pawls catching on track mounting holes. Tracks supplied before
2018.
Use a plastic hammer to tap a Delrin®ball bearing in the 10 mm flathead
screw socket used for the hex key driver. The ball prevents pawls from
accidentally catching in the socket.
