Re: Genoa cut

I have decided to patch up the sail as best I could (doesn't look too bad) and use it for a few sails before deciding what to buy. If I really love this sail, as the previous owner did and swears by it, I don't want to make the mistake of bying a replacement with a much higher clew and spoil the performance in any way... I will keep you all posted. --- In Ca… [at] yahoogroups.com, "Fin Beven" wrote: > > My belief is that a high clew is a bad idea unless you only intend to reach with the sail. > > The pressures on the sail tend to push the clew out, resulting in a wider sheeting angle.

Maybe even up to the level of the pulpit / lifelines, and have the sail cut so that there is no "skirt", a straight line between tack and clew. > But not for racing. > > For an approximate location for the genoa lead car, imagine a line extending from approximately 1/3rd of the distance up the luff of the sail, and back through the clew to the rail.

Maybe a little lower in my experience but that is the rule of thumb. If your jib goes inside your rigging, there may be interference issues there as well as the same % sail will have the clew further aft if the clew is higher just because the headstay is slanted. > > > Allen > > > On Sun, Jan 6, 2013 at 4:50 PM, r good > wrote: > > > > talk with your sailmaker. You want to make sure the sheet leads correctly for the cut of the sail. Just raising the clew could call for moving the car so far aft that it would run out of track unless the sail design was otherwise adjusted. Basic design of the sail should have your genoa sheet car at about mid track. > reggie > > > > ---------------------------------------------------------------------------- > To: Ca… [at] yahoogroups.com > From: dutchessc22@... > Date: Sat, 5 Jan 2013 01:28:50 +0000 > Subject: [Cal_Boats] Re: Genoa cut > > > > Thanks for the response - the Kevlar has disintegrated within the suncover and there is a piece of about 4ft x 8" just about shredded there, just below the spreader patch. > > Since the sail will be 6.5oz Dacron and for cruising only, I will reduce the leech somewhat... Going to about 6ft less should raise it off the deck (and probably the life lines) sufficiently to improve forward visibility, do you agree? > > Thanks again. > > Paul - CAL 2-34 #411, Raritan Bay, NJ - sorry for not including my sign-off in previous posts. > > --- In Ca… [at] yahoogroups.com , "Husar, Charlie [USA] (ASE)" wrote: > > > > HI, Dutchess. Yes that racing sail was a deck sweeper. Seeing under the sail does not work well. I always have a watch below (also trimmer) when racing with sails like that. I higher cut clew (shorter leech) is desirable for cruising. Does affect performance some, but not that much. You probably would not want to go as high on the clew as a yankee.
