Recutting a Sail for a Furling Unit

I have a hanked-on Genoa. Does the sail have to be recut to work with a FF2 furler?

Great question, and the answer really depends on the length of the leading edge of the existing headsail. The sailmaker’s rule of thumb is that the luff (leading) edge is cut to be about 95% of the forestay length. This generally means that by the time the furler drum and head swivel (if any) are in place, the existing useable stay length is reduced.

If the luff is close to full hoist, the sail almost always must be recut to shorten the luff length. The most common method for recutting the sail is to cut a wedge from the leading edge that is wider at the top and tapers to nothing at the tack (lower, forward corner). Click here for instructions on how to recut the luff.

If the sail is not full hoist, you can simply cut away the existing luff tape (grommets, hanks and all) in one clean cut, and then install #6 continuous support tape (size appropriate for the Flexible Furler). Create new attachment points at the top and bottom of the sail with loops of 1″ tubular polyester webbing. Secure a stainless steel ring in the loops for larger sails. Smaller boats (under 30′) do not require rings.

Don’t forget to add sun protection to the furled sail by sewing a sacrificial cover onto the leech and foot edges of the sail. You can install a sacrificial uncover using Sunbrella or UV Insignia with kits from Sailrite.
