If I can add my 2 cents to this equation as my background is sailing Beach Cats and we don't know what a stinkin reef is on those boats..the reef solution to us is more BEEF on the trap line J . Anyway when I bought my M15 from Stan it would be polite to say that his sails were pretty blown out since Stan sailed big winds on the Lakes up north. This gave me a chance to have the Wonderful Dr Judy B at Hyde cut me some nice new sails. I HAD THEM CUT FLATTER for 15-20 knots of wind that I expected to encounter on the Chesapeake bay. I'd rather point up with a flat set of new sails that de-power with a stock set or blown out set of sails. Funny that last year my wife and I sailed in 18-20 knots full set up on the M15 and she sat between my legs and I sat up on the coming to get more leverage BUT we both hugged the farthest point forward in the cockpit to get our weights forward and out. I also had upgraded to the IDA rudder which I felt dug deeper and prevented cavitation and it certainly did not have much weather helm. The big chop on my broad reach home was more worrisome than my up wing leg. I called Bob Eeg after this sail cause it was a hoot, the wife liked it too. So if you expect to sail in BIG winds and u need new sails consider designing your sails for those conditions, you can always put more bag in a flatter sail with proper controls..or get a Trapeze set up and have more fun. Hey Sal you hearing this convo and I am thinking how nice a deep center board and single easy reefing sail would be..take this convo over to your forum J for follow up.
