To be used if angle between halyard and headstay is less than 7°. This
is common on masts where halyard sheave is very close to headstay.
USE ONLY IF NECESSARY
If halyard angle is greater than 7° and halyard is wrapping a halyard
restrainer may not be necessary. Halyard swivel must be near top of
foils and headstay must be tight. This will prevent halyard wraps in
most cases. Consult furling instruction manual.
3. Position restrainer on mast so halyard is at a 7 to 10° angle to
headstay. See drawing on reverse side.
If necessary have a sailmaker cut down top of sail to create a 7 to 10°
angle between halyard and headstay.
With restrainer installed, halyard swivel will ride lower than installations
without restrainers. This is necessary to achieve correct halyard angle.
