I just bought a roller furling system for my Ericson 23, and I want to replace the headsail. I plan to be doing lots of singlehanded sailing, what size sail would be best and any recommendations of sailmakers would be appreciated. The current headsails I have are pretty tired, so I don't think it is worth having them redone to work with the roller furling. Thanks for any suggestions. Sailing on Lake Pend Oreille, Northern Idaho.
