I just purchased a new main for my C30 tall rig. The loft says it has a 37' luff and that is what I should have. I assumed they knew the right measurments so I didn't actually measure the mast or old main before buying the new sail. I have not measured the new sail since I keep forgetting to take my long tape measure with me to the marina. But the head of the sail, when fully hoisted, is about 1.5 feet from the masthead. My question for all you tall rig owners is, is your mainsail head all the way (or very close to) up to the masthead? Somewhere I read that someone had his mainsail luff cut a foot or so shorter to better balance the boat and minimize weather helm. Any comments on this? Thanks! Chris

Std. rig
The luff on my Standard Rig is 35' I believe. It goes nearly to the top of the mast. I can vary that about a foot by keeping the boom down all the way with the downhaul. 37' sounds right for a tall rig. My foot and leech are 11.5' and about 36.5' respectively.

Seem to be right
I just checked the database at sailrite.com and they have P=37' for the C30TR. Keep in mind that as the sail wears it will stretch some so you dont want to use all available hoist while new. You might want to compare your boom's height above deck to other tall c-30s. With 1.5 feet to work with you might possibly want to raise your boom a few inches for additional head clearance.

The Sail Loft should
have gone to your boat and measured it (if you got the sail from a local loft). If it is wrong, I would return it. Check with your loft.

I have thought of that
Raising the boom was something that came to mind early-on. Right now it is screwed to the mast just below the widened out area where you insert the slugs into the mast. I suppose I could rig a downhaul and not re-attatch the boom with screws and adjust the main height that way.... Thanks for the replies so far, guys! Chris

The Right Sail
Maybe it's just me , but if you are unhappy with the sail you just purchased return it! If nothing ealse have the loft make it right for you! I'm sure you paid a nice sum for the new sail, so why not have it be what you wanted? If you purchased this sail from a local loft they should have done all the measuring themselves and they should also have resources that would tell that these measurements were in the ballpark. If a loft wants to make a truly good and correct sail they should be willing and able to do this. If you used a mail-order loft, having things come out right is one of the chances you take from afar. It is sometimes hard to convey ideas and wants over the phone or by email. I'm not saying any or all mail-order lofts are bad, just that it can be hard to see what you are geting without physically showing them what you want and then seeing it done! I think there is something wrong with the new sail if you have to move the boom to make things right. The boom shouldn't have to be touched! You should be able to bend on the sail and go! I hope I have given you a few things to think about but maybe it's just me? Good Luck!

Bob, Thanks for taking the time and energy to reply. In my original post I was looking for specific answers regarding your luff length (not mast length)since I wasn't at the marina to measure myself, where the head of your jib ends up in relationship to the masthead, as well as if you have (or know of) someone who has intentionally cut the main luff a little short to depower the tall rig a bit. As you know, sailing on SF bay doesn't necessarily require a tall rig for power.. I know, of course, that I can return the sail if it is cut to the wrong length and I have been in contact with the loft explaining the problem. I am going to measure it next time I am at the boat and go from there. Meanwhile, I was looking for experience from fellow C30 owners in the areas I asked about. I have seen pictures here as well as other internet sites that show some main luffs a little short, about a foot or so, and I was wondering if anyone has done this intentionally and what it accomplished for them. As far as the boom movement....it would give more headroom in the cockpit but would also move power higher up the mast. Maybe make flaking the main a little more difficult on the leech end of things. Any thoughts on this? Thanks! Chris

Envelope, Please...
I measured the luff on the mainsail yesterday. 36' 8". Apparently this mast isn't the original mast? The sail I purchased was a Rolly Tasker sail and I am quite impressed with the quality. Not sure if I am going to mess around with the boom or not. Chris
