Hello Bill-

Along time ago [20 years approx] we had a conversation about you cutting the nose of a SC20 and then stretching it out about 4 feet. You then took it out and tried it on both tacks with a noticeable difference. I am really curious as to where the theory and practical experience merge into the final design. I would think the R/D would progress until max velocity/stability is reached. Of course I know back then we didn't have computers at home. I believe there was a RC24 then the SC22. Was the RC27 part of this development from that experiment?
