Re: Thoughts on jib sheeting inside the shrouds

You can sheet your jib to the base of the mast if you like, but it may not help you point any better or go any faster. Closing off the slot between the jib and main by tightening your sheeting angle may create so much backwind in the main that it is counterproductive. You may point higher, but if it cuts your speed by 3 knots and increases leeway, it's not really helpful. Having an existing setup led to the rail lends to a guess that the sails involved here are not less than 2 years old, and may perhaps be somewhat blown out. At best they were cut for a more modest angle of attack than the one you're contemplating, so may not perform well at all if sheeted in at a tighter angle. The best way to find out before going crazy buying hardware and drilling holes, is to try what Don suggests first. Rig up a barber-hauler of some sort that will lead the jibsheets inboard: Attatch a snatch block to a line and cleat it somewhere on the cabintop so that a jibsheet running through the block is inside of the shrouds. Then lead the sheet back to the winch so it avoids chafing points, of course. You may need to use a hefty snatch block - you don't say how big your boat is. Do the same P & S, and see what it does. Does the jib shiver at the leech while the luff is full? The draft of the sail may have blown aft, calling for a new or recut sail to work with the new angle of attack. When you sheet in the jib does half the main start to backwind? You've closed off the slot too much, which means you're putting on the brakes, not the accelerator: ease off the barber hauler to open up the slot. If you're lucky, the tighter angle will enable you to avoid some of the chafe you mentioned and point higher without going too much slower. Try a bunch of different barber-hauler positions to see what works best. It could be that a single padeye on each side could work the changes you seek - much cheaper than a track with a car, and a lot easier to install. You could also find, like Don, that the barber hauler works well enough to not need anything more than that. Have fun playing!
