As there is no max. weight or min. sailarea or other min. constants, why not let a sub-optima boat race? I would gladly let the SL16 race, but would it be fun for the SL16 crew? Perhaps if they are lightweight?
The F-16 is too light to measure in as an F-18. Pour 80kgs (?) of epoxy into the hulls, and I think you will measure in. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
