(johnbslocombatgmaildotcom) Hi John, It's a CDI, which has it's own pulley built in at the top of the foil. See page 2 for the diagram. http://www.sailcdi.com/sailpdf/FF4&6...ual%207_06.pdf That leaves both forward halyards (I have two) free for other use. The port one is the one I use for the spinnaker halyard, while starboard serves as the pole toping lift. Ah Ha! Yes, I should have thought of that as I used an Australian made system, similar to what you have, when I built a mainsail reefing system on my boat. Probably the reason was that I somehow associate "halyards" as being a line to the top of the mast. (which I suppose it really is in reality :-) Cheers, John B. (johnbslocombatgmaildotcom) |

That's one thing about stranded rope--I don't care how _easy_ it is, a splice in the braided stuff just doesn't _look_ right. I always though that eye splices in double-braid looked rather slick. Much nicer then eyes in plastic three strand with the ends sticking out :-) Cheers, John B. (johnbslocombatgmaildotcom) |

Perhaps for replacing it with a storm jib in serious weather? I guess that partial furling could do in place of reefing. It _can_, but it's a real bad idea to actually do it.

That causes the fabric to be stretched in the middle of the sail, causing it to shape about like a dirty diaper. And it's a permanent stretch too. The jib that come on my boat has three very distinct scallops that are easy to see in light air. When the wind picks up, it has way to much camber (depth of curvature) - bagged out too much... I've been playing with the idea of removing the roller furler and going back to hank on jibs. That way I can have the right sail up to match the wind conditions. I've had some trouble rolling that bad boy in a couple of times when the wind picked up over 20 mph rather suddenly. I guess I tend to carry too much linen too long. But even with the headsail rolled up, in a big wind that's a LOT of drag in exactly the wrong place. Normally, the jib acted as its own downhaul in my experience -- but this craft was made long before roller furling was thought of -- and before the Marconi rig had the right strength of materials to be practical.
