34th America's Cup: multihulls!

Ok, conceptually correct. However, the heel in this case is rather small, and so is the vertical force due to heel. In case of a daggerboard which produces the force just due to the heel, the art. 1.4.e is complied - the primary effect of the daggerboard is the anti-leeway force in that case.

But here, again, we have daggerboards intentionally shaped and designed to produce much more (i.e. three times more) vertical lift than horizontal. So, imo, the two cases are not really comparable... In the AC case, there is an intention, by design, to create a huge amount of vertical lift. In the heel case, it is a by-product of speed and heel.

===========
Slavi, in Toms post 1846, he suggests 6 tons vertical lift and 3 tons horizontal lift....... There is some lift developed by the angled curved portion of the daggerboard and most vertical lift is coming from the "L" portion of the board.

Someone mentioned that if your boys win they're going back to leadbellies-is that what you hear?

 

IMHO you'll get the sponsors if you race something the average punter can relate to

Have you seen the Nacra F20c foiling in the LAC thread? Hydros team....

 

do you have the link Doug?
Thanks

 

34th AC

Hydros is using an AC inspired three foil system: (see the LAC thread in this forum for the first picture from Hydros of their C Class foiling using the three foil system pioneered by the AC boats)

That phrase (which may have been used before) came into major currency after the 1934 "luffing incident." That incident prompted Gerard Lambert (who was as far from Larry Ellison as another successful businessman could get) to sail Yankee to England in 1935 and race as a gesture of sportsmanship.

Cheers,

Earl

34th AC lynch mob exposed

So the uninformed lynch mob is all mad at Oracle for wanting to have adjustble rudder foils,huh? An you're willing to destroy the reputation of good people to push your uninformed agenda, right?

Well, get this from the Iain Murray news conference going on right now and posted by "Mr. Clean" who is there-post 17 in Murrays law thread in AC-SA:

"where did you hear that adjustable elevators til just before the race"

"Dean Barker email dated December: 'I would like to look at adjusting until the start of the race'"

It was TNZ who suggested it!!!!!!!!

Clean, post 22:

Q: ETNZ has stable foiling, Oracle does not. This rule will change the balance between the teams, right?

A: Performance was not my job, and was no part of recommendations.

SF Chron on Murray: http://www.sfgate.com/sports/article/Director-threatens-to-scuttle-America-s-Cup-if-4645262.php

(07-03) 11:15 PDT -- In the latest twist to the contentious America's Cup, regatta director Iain Murray threatened Wednesday to scuttle the regatta unless his safety recommendations are upheld by the Cup's international jury.

The five-member jury is scheduled to meet Monday to hear a protest by Emirates Team New Zealand and Italy's Luna Rossa Challenge over Murray's recommendation regarding rudder elevators.

These are the winglets on the base of the rudder blades that help control the pitch of the boat. The configuration of the elevators is the only remaining unresolved part of Murray's 37 recommendations following the death of British sailor Andrew Simpson when Artemis Racing capsized on May 9.

If the jury agrees with New Zealand and Luna Rossa, Murray said he will go back to the Coast Guard, which issued a permit this week, and say he doesn't think the racing would be safe.

In that case, the Coast Guard would almost certainly withdraw its permit. "Without a permit to race on San Francisco Bay, there will be no regatta," Murray said.

Tom FitzGerald is a San Francisco Chronicle staff writer.

"Wethog" an anono on the right side and Clean:

It was interesting to me because ETNZ fans have placed OR as the source for all the supposed shaddy changes to the rudders, that OR wanted to adjust their rudder foils right before the start, but that bit showed that good old Tripod[Dean Barker] first proposed that "safety" change, not someone from OR. And subsequent posts by Clean show ETNZ and ETNZ-LR have been fully involved with all of the 37 safety recommendations and agreed to them "in principal". Now all of a sudden they have a change of heart. Why?

Regardless, some on here have been busting OR's and IM"s balls because it was ASSumed OR was trying to change the rules to suit them, well it doesn't appear to be that way.

Clean:


I think it is pretty obvious that ETNZ and LR are being opportunistic feeders here; they have now had the time to watch OTUSA 2 pitching around unstably, and figure that they have a better chance against a hobbyhorsing Oracle than under a more controlled boat. I think it is that simple.

The other factor is that, even if they like the elevator changes, ETNZ/LR really, really don't want a precedent set that allows Murray to circumvent class rules any time he feels like it by just amending the MEP.

Talk about disingenuous: (from the NZ Herald-- http://m.nzherald.co.nz/#!/sport/news/article.cfm?c_id=4&objectid=10894680 )

Murray said he finds it difficult to understand why Team New Zealand and Luna Rossa are protesting when both teams said they were supportive of all 37 safety recommendations when they were unveiled at a meeting on May 22 following extensive consultation with all the teams.

"After that meeting Grant Dalton came up to me and shook my hand in front of the other teams and said 'you won't get any push back from Team New Zealand'," Murray said.

 

Doug, for heaven's sake, how do you manage to publish so many posts in such a short time???
