Dermot,
What is so different about the B Class that would make it a better choice than the HT? OK, its longer and wider-what else? Not much.
The HT rules will encourage development, however I would not be surprised to see a new rule regarding mast max chord to protect againt wing sails.
Wouter,
The point is not that the HT is the fastest beach cat, as it certainly is NOT. It is in effect a developmental class and not a true formula class, IMHO. This fact makes it an excellent choice for this event. I know that you have held some disdain for the HT class, after reading your post over the past year. For this reason, I was waiting for your post and you acted as I expected.
The choice has been made and the Little America's Cup (ICCT) is going to using F-18HTs for the foreseeable future. It would be advisable for designers/sailors that covet the cup to begin planning their F-18HT projects. I see that John Pierce of England and the folks at Flyer in Germany are already getting their new F-18HTs ready! This is exciting!
