Speed Costs, How Fast Can You Afford To To?
First and foremost, I wouldn't buy any sail larger than your local PHRF rule. It will have much less resale value than a "legal" one. I understand that the winds are light for most of the season in the Dallas area. I'd get a size to match the most prevalent conditions. Don't worry about windy days, that's what your 110 is for. Don't get a foam luff - it will detract from very light air performance. If your checkbook can stand it, get a radial cut rather than the standard panel cut. These hang better and will hold their shape better. The sail maker can also vary the cloth weight in the panels, which will also make it hang better. Buy a laminate instead of straight dacron, this will eliminate a lot of drag. If this is going to be truly a light air sail, get a deck sweeping low clew cut. You'll be amazed at the performance difference. If your worried about changing conditions, then get a higher clew.Your excessive weather helm is bothersome. Your current sails/rig might be blown/stretched. You should be able to sail the boat in balance in moderate winds. It is true, a larger jib will give you more drive and move the center of effort forward. If weather helm persists, traveller down and apply more backstay tension. But chances are, your main is blown and you are looking at a bit more than you bargained for.
