I suspect that I'm going to need to haul the top of the sail further to windward, to keep it full and pulling. A "wall-to-wall" sheet track and traveller would be best, but that would be expensive, and not very practical. Accordingly, this morning, I've rigged up the arrangement that I described in Newsletter no 21, pages 24 - 25.
Well, I tried that last season, and didn't like it. Not because it didn't work, but because it made it difficult to hoist sail with the lines lying across the cockpit. so I reverted to having all blocks on the cockpit sole. Towards the end of this season, I've moved the deck blocks to a temporary lash-up position at the transom, and I like this better. With a less vertical pull on the sheets, there are much lighter sheet loadings. This winter, I'll make a beam to bridge across the legs of the pushpit to make this arrangement permanent.
I have five-part sheeting, so the right-hand diagram applies, except that I also have upper and lower sheets, so the upper three battens are controlled by the upper sheet, the lower two by the lower sheet.
This summer, I've been noticing, more and more, that in light airs, I've sailed with just the lower sheet active, just taking the slack out of the upper sheet - more twist is needed to keep the whole of the length of the luff lifting at the same time. As the breeze increases, so I put more tension on the upper sheet - the need for twist is reduced. As the breeze increases again, and I take two or more reefs, so the lower sheet is taken out of play and I sail entirely on the upper sheet. Control over the set of the upper part of the sail is much better with the reefed part of the sail not being affected by tension in the sheet.
