sailmaking questions
try looking up a freeware program called sailcut. it is a perfect
program for projects like this. William R. Watt wrote: William R. Watt ) writes: shape: ..... I don't think you will have to cut your 5 ft bolt into panels. 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. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-freenet email must have "notspam" in subject or it's returned -- remove "abcde" from e-mail address to reply "I think it would be a good idea."
