I have been a sailor for over forty years and i have considerable experience in a wide variety of sailboats and even some power boats. I have raced at the highest levels and cruised for many years with my family. I have met and sailed with some of the finest sailors in the world and I owe sailing a great deal - including meeting my Wife. I have taught my Daughters to sail and love sailing - My eldest just took her housemates sailing in Cancun Mexico and they all had a very good time. I did not write about this to make you jealous. You are absolutely correct about this boat minimizing drag resulting in explosive speed. These boats were WAY ahead of their time - and the AC boats and the C class cats have foil sections that are basically the same as those used many years earlier on the Trifoiler. On a dollars per knot basis this design is one of the best performance values EVER made. Used ones in good shape are out there. but rate.
Yes the youtube videos tell the tale quite well. It is an incredibly exiting and entertaining boat to sail. Fast is fun - no doubt about it.
