No scale shows on the drawings, so you may have to print out a copy and use dividers to space out a scale of your own. The “P” dimension of 34’ for the mainsail is the length between the black bands on the mast. Half of that will be 17’, half of that will be 8.5’ etc. You can double-check your scale by using the LOA of 30’ and doing the same thing to determine 15’, 7.5’, etc.
