Question about sail area
Designing/building a small sailboat. I need 100-110 square feet of sail for her. I have chosen a Gaff cutter rig for the sail configuration. My question is that if i intend to use the main sail along with only the nearest headsail for standard sailing, do i make these two the 100 square feet, or should the 100 square feet also include the topsail and the fore headsail, which i dont intend to use all the time so that i have backup for lower wind days? that would leave me flying with way fewer area on days that i dont extend the other two sails.
