Re: AC75s

Freaky cutting edge, just like the AC should be doing.

I wonder if they'll be safer than the big foiling cats. The only objection I had was the level of risk the crews are exposed to for others enjoyment. I don't buy the argument that the crews are professionals. They will accept any risk thrown at them, as the attraction/advantage of being named to a AC crew is too overwhelming.

I don't know, I suspect most of the guys would jump at the chance to race those boats regardless of the risks!

I suspect the monohulls could crash just as hard as the cats did. I am looking forward to seeing what they can do!

Re: AC75s

I think the pendulum has swung too far towards the focus on electronics, technology and rule-beating and away from match racing skills. Couldnt we have exciting high speed racing on VOR type yachts without having to go to the bleeding edge that the AC boats seem to be pushing?

Re: AC75s

I like sailing machines, they are most definitely sailing machines

I bet they are a blast to sail. I expect there will be some spectacular wipe outs. Picturing spin out broach rolls.

Re: AC75s

Interesting.....to me they are closer to a SpaceX rocket than a sailing machine

I agree. That was my point. A bunch of billionaires fund the construction of the these machines and the professional sailors will never pass on a opportunity to crew an AC boat, regardless of the risk. It's gladiator-like. The billionaires watch for their amusement, while the sailors potentially get hurt. Maybe I'm being too dramatic.

On the other hand, the AC should clearly be a test bed for new design and technology. It's been that way, since the original America (a model replica of which sits in my office, btw). This proving ground has been very good for our sport. We'll see if foiling cats and monos ever become mainstream cruisers, however. My guess is the technology is only used to lift our future cruisers slightly, reducing wetted area and increasing speed, but not for flying a hull.

Re: AC75s

We had a foil hydrodynamicist from Oracle give a talk at our club about the issues involved with stalling, and cavitation at high speeds. He had some incredible videos. The windward foil sticking so far outboard could make roundings and w/l situations interesting.
