Double grooved furler for JCII
I have an old, bullet-proof, hell for stout Famet furler. These came with twin grooves. Since the halyard is integral to the furler (comes down the other side of the extrusion), you had to order a second halyard, if you were going to fly AND FURL twin headsails. Although these furlers are almost failsafe, they are pretty darned heavy, and it is a bitch to raise a sail while underway, given the position of the halyard. However, you can, quite easily, use it just as a headfoil, and raise a headsail with a normal halyard. You just can't use it as a furler. I have rigged up various blocks, etc., to improve on the existing system, but using the integral halyard would never be quick enough for racing. Using the boat's regular halyard might be, however. In practice, I leave a 120 permanently on the furler, raise a 110 with the normal halyard, if I want to fly twins, and fly a storm jib from an interior stay, tacked to a three legged bridle attached to the old stem fitting, and the toerail on either side of the aft bulkhead of the anchor locker. This is on the H33, by the way. Famet was recently resurrected, by the way, and still makes these furlers, which have never yet had a major, blue water failure. But they ARE heavy!!
