170% Genoa on a CD 25

[eric]

This spring, I broke out the 170 Genny that came with Allia. It's a lot of sail, but has been managable up to 15 knots, or so. My question is where to run the sheets. I have them leading through the blocks on the slide track in the furthest aft position (which is about 2 feet aft of the winches. Even this far back, however, the sail seems to loose it's shape (It gets baggy unless trimmed way in).

It's kind of hard to describe, but I'm faily certain the sail would trim better if I could lead the sheets further aft. Should I try running them all the way back to the spinnaker blocks? Am I overlooking something? Comments appreciated.

Cheers,

Eric,

Saw you last Sunday between the Brimbles and Satan. It doesn't surprise me that the jenny track isn't long enough for a 170. Some sail makers will draw a line on the clew to give you a sheeting angle starting point. You'll need tell tales a foot or so back from the luff to be sure. While close hauled all the tell tales should be flowing aft. If the top inside ones hang and the bottom inside is flowing the jib lead is to far forward. It's better to ere the other way with the top of the sail more open. Sounds like a longer track or finding a sheeting position you're happy with and through-bolt a pad you could then attach a block. I'd guess if the spin. block is all the way aft that'd be to far. See you out there.

Thanks for the help Eliot. I do remember seeing you out there on Saturday. Looking good:)

Actually the telltales were reading that the sail was filled just fine. I had no idea there were any problems until I got back some photos taken last weekend and it looked butt-ugly. The luff seems to be fine, it's the clew that appears misshapen in the photos. It's really hard to describe. I should post the photos and let everyone evaluate for themselves.
