I've made a very rough comparison of three sails, all at 31.2 sq m, SA/D 15:
1. Low AR, fanned, yard 4.1m, battens 5.02m, six sheeted points with single sheet, two unsheeted battens, mast minimum LOA 9.5m.
2. Medium AR, yard 3.77m, battens 4.34m, six sheeted points with single sheet, all battens sheeted, mast minimum LOA 10.5m.
3. High AR, yard 3.3m, battens 3.8m, eight sheeted points with upper and lower sheets, all battens sheeted, mast minimum LOA 11.5m.
