Lakewood, Colorado | 10 race scenario - my guess is that after a couple of races the A5 crew would be more in tune with the boat and things would even out a bit, with the overall advantage over 10 still to BOR. Two considerations, First, How long do you think it would take to get in a 10 race series? Given that it took a week to get off just one race, that might be a three month proposition. Second, do you think either one or both of those boats really has TEN races of durability built in to them ? I don't. Just something to think about. It WAS fun to watch, and I am really looking forward to seeing them match up on a reaching leg. Stephen

I guess technically when either one is riding on one hull they're a mono...
I was also noticing on the replay that A pitches a lot more in the waves upwind - I hadn't noticed it as much watching live. There was a definite contrast to BOR being more steady and A pitching.
So, my new winter project - canting wing sail and banana boards on my F-27...
Can't wait to watch tomorrow...
On one hull they are monos... but for ballast, stability, hull shape, drag, speed, etc. The pitching difference relates to Alinghi having bow overhangs to measure at 90 ft LWL, while BMWO's floats are free from measurement restrictions, the boat resting on the mainhull for measurement. BMWO is better balanced. It also relates to the inclination of B's amas, as I posted before in this same thread. Also dreaming of a wing and curved board, but already have a cascading system for canting. Yes, the overhangs of A5 give a keel shape that would seem to not counteract pitching, essentially adding rocker forward. My 6.0 does the same thing (deck is flat, but the keel actually has decent amount of rocker). They had used S boards before I believe. As for BOR, I would characterize the amas more by the profile given by their keels, stems, and decks - that's what gives the characteristics. Saying that they are inclined gives words to the eye cues, but it's not that the designers said "hey, let's just take the amas we have and point the noses down", then again, maybe they did... Either way, the amas have buoyancy forward and low, and the boards are helping provide more. In the end we're saying the same thing differently. A5 pitches, BOR does not. Canting system looks good, I'm stuck in the real old school with a non-rotating fixed spar. Maybe that's my first step... | | | Re: America's Cup Countdown

Annapolis,MD | Was A5 pitching more from the water ballast? Once they blew the water out it seemed to handle better. Hmmm, don't remember. It was after the first tack about 2/3 of the way to the second tack upwind. It was most obvious from shots from the lee of A5 that showed both boats. It wasn't out of control type pitching, but it seemed more than BOR was experiencing. | | | Re: America's Cup Countdown

Stephen I do think they have plenty in them. the BMWO platform has been in existence for three years and gone out and sailed 200 mile days regularly during that time. The wing has actually proven to be quite reliable although it's would certainly require some maintenance here and there. I think we'll be a little surprised with these boats. Expect some speed trials and testing after the matches are done
