Last week I found out a 150% genoa will sheet to the cockpit coaming track when made properly. Anyone flying a 135% on an Oday 25 and to where does the sheet (block) go??

I've read where there is a rule of thumb when it comes to sheeting a Gennie or Jib sail. If you can draw an imaginary line from the center of the sail's luff to the tack of the sail, the sheet needs to be right in line with this imaginary line coming off the sheave block. Then the block can be tweaked a little one way or the other depending on how you want the sail to be shaped in relation to the set of mainsail. Bringing the block in toward the bow a little will give the sail a tighter leech and a looser foot, and visa versa.
Thanks Joe and you're right. I wanted to know if anyone was using a 135 and where that block or track ended up. I have'nt even bought the sail yet. But before I purchase a used sail, I want to know what mods will be neccessary.
It's always helpful to know what will work on your boat so you don't have to go to the expense of making changes in hardware. We have two O'Day 25s and one O'Day 26 in our club and they all have CDI Roller Furlers. If I ever win the lottery I'm going to buy some new sails.
It has has always been my understanding that just the jib (100%) runs through the forward block. The track cannot pull the corner of the jib far enough down to make sure the top of the jib sail is producing. For all the Genoas (past 100%) you use the track moving it back as the size increases to give the sail proper shape. I have used my 135, but I am a bit lazy, I tend to use the Jib or the 150 for the most part. Some days I will purposefully sail upwind for a long time with just the jib if there is somewhat beefy winds and then when I start my trip home, I throw on the 150 and see how fast I can get the boat to go. Once the Bermuda High settles over the east coast, regrettably soon, it is all about the 150 all the time.
when you're using the 135 does it sheet properly if you use the forward part of the track on the cockpit coaming. I mean is the shape real good? Ernie
Yes
It also depends on the point of sail. If you are heading upwind I find on my boat with my sail it has the best shape with it halfway back. If I am on a broad reach about 3/4 of the way forward. If I am sailing dead downwind, all the way forward. I would only make these adjustments if I am sailing a long distance on a sustained tack. If I am constantly changing my heading I just leave it half way to 3/4 way forward.

It would depend entirely on how the sail is cut by the sail maker. The measurement from the bow to the sail track has to be figured into the equation along with the height of the mast and the length of the forestay and the height of the clew. The sail would be cut differently for the keel 25 with a taller mast than the c/b 25.
My 155 sheets close to the forward end of the genoa track.

You're right about that Rich. The foot on my Gennie is up swept for better visibility. It's more of a cruising Gennie. Most Gennies have a foot that is almost parallel to the deck and the sail clew is lower, whereas my sail clew is higher.
I have a 135 on my 25. I removed the jib block on deck and replaced it with a rail that I now use for the 135. I have a CDI furler and am able to reef down to about a 105. The track allows adjustment of sheeting angle as necessary. I think the track is about 30" long. I have it set about 8" ahead of the cockpit coaming. Hope the info helps.
