Default sailmaking questions

woops. I was thinking sprit sail here. You will have to make your sail
wider than 5 ft. The aspect ratio simplifies to twice the height divided
by the width. A 5 ft wide sail with and aspect ratio of 4 gives a 10 ft
high sail and only 25 sq ft, much too small. Increase the aspect ratio to
5 and the sail is 12.5 ft high and still only 31 sq ft. Looks like you'll
have to make the sail wider than the 5 ft bolt of cloth by cutting into
panels. You might want to include a boom in the rig.
