Furlers require a rigging toggle at the masthead. If your boat doesn’t have a rigging toggle, the forestay must be shorter to accommodate the length of the rigging toggle.

While sailing, the furler pulls the forestay to one side. Tack and it’s pulled to the other side. A rigging toggle installed at the top of the forestay provides a “U” joint that allows the forestay to hinge side to side. Without it the forestay is bending from side to side. The forestay will work-harden and fail where it is bending. Some Catalinas come with a rigging toggle. If so, we don’t include another in our kit.

Perhaps not. If the forestay is new enough (max 7 years old in salt water, 10 in fresh), and the furler design simply assembles over the existing forestay, you might not need a new forestay.

Furlers are made by hardware companies, not boat builders. A furler is suitable for use on many different models made by dozens of boat builders. Any one Catalina model was built with several different rigs. The C-28 had six different rigs and was offered in both standard and tall versions for example. With so many variables, only the owner, after measuring, knows for certain what length to trim the foil to.

A furler requires a tiny bolt rope (also referred to as a luff tape), that slides up the groove built into the furler foil. The sail must be built or retrofitted with the correct size of luff tape to match the furler’s requirements.

Yes, there are three differences between a furling and hank on sail. Furling sails have a bolt-rope, a sewn-on cover, perhaps a foam luff to shape it when reefed, and they are cut somewhat different than hank-on sails.

If a hank on sail is near the end of its life, it may be a candidate for converting just the luff. Know that, uncovered, the sail will rot in the sun… but it’s near the end anyway, right? Get a couple more seasons out of it and then buy a new sail.

If the sail is fairly new, the inclination is to convert it. But add the cost of conversion, the cost of the cover, plus the used value of a good sail… Is it better to sell it and put that money toward a new sail that is purpose built to be a furling sail? You decide.

The most common reasons for forestay failure are:

a) Lack of a halyard restrainer, or halyard restrainer mounted too low or too high for current sail (see your furler’s instructions) Note: CDI Flexible Furlers don't use a halyard restrainer.

b) Inadequate forestay tension allowing forestay to sag (tune the rig)

c) Lack of a rigging toggle between the top of the forestay and the masthead

d) Age… Don’t cheap out! Replace your forestay in a timely manner. If it fails and you lose your mast, Catalina’s original cost-effective rigs are no longer available. Current replacements are so expensive your insurance company is likely to total your beloved boat if you lose it.

Contact the your furler’s manufacturer or visit their web site for the installation manual for your model and vintage.

It’s called a Snap furl because the two halves of the luff foil snap together, interlocking along their length around an existing forestay. However, the C-22 and C-25 were not equipped by the factory with the required rigging toggle at the masthead, so typically the forestay must be shortened to accommodate the rigging toggle. That’s why our complete Snapfurl kits have a new forestay included.

In addition, the interlocking luff extrusion is made of high grade Geon PVC. It is more tolerant than an aluminum extrusion of the extra abuse it will see if you trail your boat frequently.

The Snapfurl, once assembled, cannot be “un-snapped”. If the forestay needs to be replaced in the future, use our Trim-2-Fit forestay and install the second end onto the forestay after the bare end of the wire is fed through the furler.

The CF500 is suitable for a Capri 22 or Catalina 22. It will also work on a standard rig C-25 for lake sailing. If you have a C-27 or a tall rig C-25 or you sail your C-25 in more challenging conditions we recommend the more robust CF700 that employs stronger anodized aluminum components.

The CF500 uses a #5 luff tape, the CF700 uses a #6. If you are upgrading your C-22 furler from a CDI Flexible Furler to a Schaefer Snapfurl and you plan on using your existing furling heads’l, the luff tape will must be converted from a #6 to a #5.
