thanks, Jerry, Guess I will wait until I got again before considering new sails. Tom B M17 #258 On Wed, Aug 21, 2013 at 2:34 PM, jerry montgomery <jerry@jerrymontgomery.org

An ideal sail will have the maximum draft about 40% aft of the luff (differs a little with different boats), with a nice, easy curve. When you add luff tension, it moves the draft forward, and normally in more wind you need to do this to keep the max draft from going too far back. On a sail that's 'blown out" you won't be able to keep the draft where it belongs and the sail will tend to be too full back towards the leach, which really puts the brakes on. On a good sail, in a drifter or pretty light air, the sail will be shaped about right with very little tension.
Sails for heavy air areas should be made of heavier material (less stretch and last longer) and flatter in general but the sailmaker needs to be careful; a mainsail on a masthead rig like an M-17 should be a bit flatter, but on a fractional rig like an M-15 or a Sage 17 the mast will bend off and will flatten the sail when doing so.
If I were sailing a 15 in a place where the wind blows 20 to 30 every day I'd get a smaller jib, flatter, and with heavier material. You'd go just as fast, and reef less.
Ask the sailmaker about material weight; they know WAY more than I do about things like that.

thanks Dave,
This is very useful information. I must admit, I really can't tell by looking whether or not a mainsail or jib has seen better days or not. Perhaps if I raced boat to boat often enough I could start to tell but.......is there some sign or detail or test I can run so I can make an informed decision about whether or not to replace sails? My boat dates from the late seventies and I don't know how much or how hard it has been driven and these are the original sails. Is that alone enough to warrant replacing them?? Is there one type of cloth that is better than another to make them out of? From past emails on this site a flatter cut sail would be advisable where the wind is often 15 knots or more. Any thoughts on this matter? Fairwinds, Tom B M17 #258

IMO the two best lofts for the M-boats are JudyB with Hyde , as already
stated, and Harry with Elliott/Pattison Sailmakers - www.epsails.com
both these persons know Jerry's boats, i speak with each every couple of weeks and are both great to work with.

I am going to purchase some new cruising sails for my M15. Those of you who have purchased recently, can you give me some ballpark figure for what you paid and what you got? I would be happy to take the posts offline. Thanks!
