I am thinking of buying a motor sailer, but its sails are pretty small. (I think)
The hull is a Roberts 43 extended to 48, custom pilot house etc,...
Good concept, im into junk rigs, and am interested in chipping into to design.
Who knows the ratio formula for size of junk sail to hull. If i have a 48’ steel roberts, with a bilge keel, what sail power will i need?
