second thoughts, I wonder if any of them will actually be even able to sail the damn thing around the course. they must be enormously difficult to handle.
Look carefully at the windward daggerboard at about the one minute mark - bottom section curves into the horizontal to create lift. Small foils on the rudders as well. Don't know if there is any mechanism to control pitch.
got it. thought it must have been something like that.. I obviously haven't been keeping up with the play, mind you, we should have seen this coming.. hydrofoil meets 72 foot catamaran... no wonder they've started wearing helmets and oxygen packs... this is felix baumgartner territory.

Hobiejoe was the name of the first sailboat I jointly owned, way back in the day, a venerable, even then, H16. Had a couple of H18's and raced them a fair bit as well as doing lots of club racing and deliveries as a fully-paid up member of the OPBC (Other Peoples' Boat Club). Had a joint share in a Tosher, a pretty little 18' gaff-rigged Falmouth working boat, then helmed a J80 for a year for a mate who wanted to campaign her. Not too succesful, but we had fun.
And then Sprog No.1 appeared and that was pretty much it, except for using up all my Brownie Points in one go by going to sea for nearly a month, in the course of which I missd Sprog the second's 1st birthday. If you wade through my journal entries you can find (almost) the whole story
Sprog 2 has agreed to resume Not Drowning lessons at the local swimming pool, so I'm hoping for some family sailing next summer.
Bugger. Writing out even this shortened list makes me realise how lucky I've been and how much I need to sail again, this time with all the family.
How about you?
We've had a number of boats, power and sail. I even built a 19' sloop. The stupidest thing I ever did. I could have bought and paid for a nice boat for what I put into "Fatso". She sailed great and we had a lot of fun times with her. Materials cost was about $ 12,000. It took me 10 years. Sold it for $ 2,500.
Anyway, kid grew up, we sold the ski boat, got the sailing bug again so in 2009 we bought a 1994 Hunter Vision 36. The Pearl. We have so much fun cruising the bay and the coast with our yacht club friends.
My suggestion to you is get yourself the biggest, safest cruiser you can and get your family out there. You'll build fond memories and your family will learn some skills.

In August we sailed across the bay and scored a sweet guest slip at Hyde Street Fishing Pier, walked down to the St. Francis YC with a couple bottles of wine and sat on the sea wall and watched the AC 45s race. There is nothing like seeing those machines up close. Amazingly fast.
Next year we'll just anchor out and watch the AC72s race. Being on shore is just too crowded.
What do you sail?
*edit* I remember you saying you were going to go, they are awesome in close quarters.
What do I sail? Whatever I can!

MOD70's are fast boats, but have enough heft built into them for offshore work, and they're pretty much one-design.
The idea of the AC72's is for a bit more bleeding-edge design to feature as well as straight forward speed. And so, as an effete European I'd say Formula One would be the better reflection of the tech involved.
As for the capsize, I guess they got caught bearing away without enough speed on to get through the zone of death.
And, BTW (caution: extremely geeky sailing gag coming up) if you based a race boat on a Nascar, you'd have to build a proa!

Latitude 38 thinks they ought to change to Mod 70s. I say bull. That would be like changing Nascar to Subarus. That crew knows the limit now. I doubt they will capsize again. If I was Ellison, I would be a little disappointed if they didn't capsize at least once before the Louis Vitton Cup.

When you say AC45 I guess you mean the cats?! Is that the way of the Cup racing now or are there different facets of the race at different times?
This seems to be the way the host club, SF Yacht club, has decided to conduct the challenge series. They're doing a series of preliminary race events called "America's Cup World Series", hosted in different locations (Plymouth, where the original race in 1851 was, Newport, RI, a common venue for the Cup Challenge) this year (one more series coming up in October in San Francisco). The actual challenge racing to decide the winner of the cup will be next year, a best of 17 (!) match race competition. It will feature 72 foot catamarans with the rigid wing sails
AC72 design parameters:
LOA 22.0 meters (72 feet) Beam 14.0 meters (46 feet) Displacement 5,700 kilograms (12,500 pounds) All-up weight 7,000 kilograms (15,500 pounds) Wingsail area 260 square meters (2,800 square feet) Total sail area (including wingsail, gennaker, and jib 580 square meters Wingsail height 40 meters (130 feet) Wingsail chord 8.5 meters (28 feet) Sail trimming Manual grinders Configuration Twin-hulled catamaran Crew 11 Sail trimming No mechanically powered systems Sail area reduction Removable top sections/leech elements Appendages Maximum of 2 rudders, 2 daggerboards Construction Minimum 600 grams per square meter outer-skin; High-modulus carbon-fiber permitted in wingsail spar
For comparison purposes, the ubiquitous Hobie 16 that I and Hobie Joe and Kurt sail has a ratio of sail area to displacement of 0.13. The AC 72 sail area to displacement ratio is 0.10. The ratio for the 12 Meter America's Cup yacht Columbia is 0.005.
Even though our Hobie 16s have a higher ratio number, the AC 72 would leave us in the dust, due primarily to the efficiency of the rigid wing sail plan, and a more efficient hull design (and greater beam and waterline length).

Plus you get punished later by the wife, more like hauling ass.
Well that happened 3 years into our marriage, and as of last June, we've been married 36 years. So it didn't ruin things much. Except for when we were on the Hobie, and the bow started to push down, she would try to push me off the stern.
Needless to say, when I raced, she wasn't my crew.
I have to agree with hj that it was pretty exciting racing. Those AC45s haul ass. And you're right, hobiejoe, it's going to be a very dicey proposition bearing away from a windward mark when a puff is hitting you; the smaller AC45s are so overpowered and minimally crewed, one mistake can spell a capsize. This was demonstrated graphically in the finish of the last fleet race on Sunday; the winning boat Luna Rossa either forgot to sheet in the jib or had the wing in too tight on the reach to the finish, and they quickly rounded up and nearly ended up on the shore above the finish line!
The addition of fleet racing was an interesting wrinkle as well. I think the San Francisco club running the show is doing a good job of trying to make the competition fair, and to bring it to a wider audience.
I look forward to the next series of races in October.
