Purpose
Ranging from 2.5 to 30T, the Rigging Projects Forward Lock covers the entire range of yachts, from performance driven race yachts, right through to
the biggest superyachts.
The Rigging Projects Forward Lock is designed to enable the sail to be locked and unlocked without the need for any trip line or external device. The
system allows the user to lock or unlock by simply over hoisting the halyard through the lock.
Use of this product for other than normal sailing vessels applications is not covered by the limited warranty.
Forward Lock key design features:
•No need for internal trip line within the rig.
•End stop within the lock allows the halyard man to know when the sail is at full hoist.
•A two-pawl system reduces the stress on the body when compared to a single pawl system.
•Coming off lock simply requires a small over hoist on the halyard.
AVAILABLE SIZES
The Forward Lock is available in a range of 2.5 to 30T.

Installation
Forward Lock Installation into mast
•Installation of a Rigging Projects Forward Lock should only be carried out by a suitably qualified and experienced personnel. If in any doubt,
contact Rigging Projects.
•Installation should only be carried out using the router jigs supplied by Rigging Projects.
•Mast tube engineering should be checked prior to locks being fitted to mast –If in any doubt, contact Rigging Projects first.
1. Working with the rig on the ground, position the router jig in the correct position on the mast and secure to the rig using the two lock mounting
bolts.
2. Once happy with the position of the lock, cut out the slot within the jig plate and tidy up with a drum sander to achieve a neat finish.
3. Working with the front cover and lower ferrule removed, tie a bowline through the ferrule hole and front cover slot.
4. Angle the top of the lock into the slot in the mast and push through until the lower edge passes through the slot.
5. Tilt the lock back to the upright position and pull towards the front of the rig until it seats in the slot. Fit the two mounting bolts and tighten to
pull the lock into place. These mounting bolts should be fitted with Loctite.
6. Fit the ferrule to the lock and fit the nylon tipped grub screw with blue Loctite to retain it.
7. Check the operation of the lock and once happy, fit the front cover using suitable adhesive.

Operations & Procedures
Procedure for Forward Lock
To Lock
1. After connecting the sail to the lock strop, begin hoisting the sail on the halyard.
2. As the spigot reaches towards the entrance of the lock body, reduce the speed at which the halyard is raised.
3. Keep raising the halyard until the spigot reaches the end stop within the lock- the line will not be able to be raised any further and tension will
occur in the halyard.
4. Once confirmed the spigot has reached the end stop, ease down slowly on the halyard until the locking pawls engage. Before removing the
halyard from the winch, increase the tack load to ensure that the lock is engaged.
5. Halyard can now be completely removed from the winch.

Operations & Procedures (cont.)
Procedure for Forward Lock (cont.)
To Unlock
1. Before removing any load on the tack, load the halyard onto a winch.
2. Once the tack is released, slowly wind the halyard to take up the tension. Only a small over hoist is required to open the pawls.
3. After a small over hoist, the halyard can be slowly eased down to ensure the lock has been released. If unlocked, drop the sail as normal.
4. If the over hoist on the halyard is too much, the mechanism will reactivate and lock. A smaller over hoist is required to open the pawls without
reactivation.

Maintenance & Checks
The following maintenance and checks should be carried out on the lock as per the below sheet.
Rigging Projects equipment is designed for minimal maintenance, but some maintenance is required for optimum and safest possible operation and
to comply with the Rigging Projects limited warranty. In general, the most important aspect of maintenance is to keep your equipment clean by
frequently flushing with fresh water. In corrosive atmospheres, stainless parts may show discoloration around holes and screws. This is not serious
and may be removed with a fine abrasive.
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can result in discoloration of part and is not covered under the Rigging
Projects warranty.
