I have been sitting on Lark plans now for about a year. Lark is a
14'3"x4'10 sailing skiff and the plans show her flying 101sqft of
canvass in a jibheaded sloop configuration. I'm not too keen on the
rig and would like to go to a single unstayed rig (chesapeake leg-o-
mutton, balanced lug, or sprit sail). My question: how does one
determine the size (sqft) of the rig when reducing from two sails to
one? Is there a particular formula or common sense rule that one
follows? Thanks for the help.
