America's Cup

Stephan,
it is a long long story, rheems long,
But he gets my thumbs up, how many skippers have done a Volvo and stuff,
And mate I build boats, after a long days grind(not these days) your posts, although brilliant, make me want to sleep, thats by no means a slurr, but should you not post that in a geeks thread for Smart and Guillermo, the likes of us artists) can not understand
Ya know I started when I was 13 in our national trainer, same as Coutts blake, Dickson. I am seat of pants sailor. was a very good dinghy boy, but heck I dont think I would have done much good with this high techo stuff

 

"She insinuates, that all that do not come number one, are Losers!!!" lazeyjack

She could get a job in the US as a reporter, or better yet, as an airhead news reader on TV. Here they routinely report that boats and ships "travel at a speed of ___ knots per hour".

 

mm, becuz of shading cant see sections, pity cos I think some sections forwards look better offwind in some boats, please can you post the EXACT body plans)

 

Nice comparing pictures from where hull volumes distributions could be easly spotted. It's clearly evident the different approaches in the canoe body lines design.
In terms of Cp (e.g.) I would guess::idea:
BMWO.........= 0,52<Cp<0,53
Luna Rossa..= 0,53<Cp<0,54
TNZ............= 0,54<Cp<0,55
Alinghi........= 0,55<Cp<0,56
That's is one more good reason to hope viewing a Final of the 32nd AC to be performed by Alinghi and Luna Rossa on prevailing wind condition of 10 to 12 kts approx. (as it has so far occured in Valencia).
Alinghi being most probably best performing downwind (depending on wind speed too)
Luna Rossa being best performing upwind (as she has so far demonstrate)
To my opinion I would personally go for an unbeatable hull upwind (thus gaining in VMG) rather then a best performing hull on offwind allures. At least on this part of the world with meteo condition such as the ones so far encountered in Valencia

 

I would print the offsets if they were pilferable, except that of TNZ of course. Might make some sense of them reading the comments.

From an raw beginners point of view,BO looks like she wouldn't turn so well
per unit rudder area,LR looks flatter in cradle section and a pretty foil with fine entry & super slabsided,maybe better all rounder? TNZ ,opposite to BO (hollows) in entry,similar mid section canoe to others but volume forward,Alingi,well,more conventional?Sheesh,help me out someone......
I don't know the date or model number.

 

Very interesting. The hulls of Luna Rossa and TNZ seem to be more flat than the others but of course, the light is not the same and it can misguide us.

 

Is that because of fine entry and narrow lower body section? (From what we can see) Even though the cradle x-section is flatter than the rest.
If you look at the sillouette of the sheer against the sky, LR looks like a scalpel compared with Alingi.

No races today and probably also tomorrow. It is blowing 25K. It is hard for me to accept big racing boats that can not deal with 25k of wind and in Valencia they can have a problem with that. Now that the summer is coming it is not unusual that the wind stays (on the sea) over the 20k mark for several days.

I intend to see the final there and I have booked allowing for the postponing of several race days due to excess of wind. I hope I am right

 

That's a criticism levelled against the Cup racers by many: big costly prima donna boats good at making speed in light airs, but too fragile to have any relation to the real world. Of course, you could say the same thing about Formula One auto racers.

They are beautiful doing what they are designed to do, IMHO.

 

F1 race on an artificial track. The boats race on the sea, a natural track that changes all the time ( racingboats are more like all ground racing machines ).

I am not talking about stormy weather. Most boats (and any other sailboat of that size) have no problem at all sailing with 25k winds, 25k winds are usual stuff so why have boats that can not handle "normal" conditions? That does not make much sense to me.

 

Italy advances, Spain holds...

It seems that "old Europe" is still going strong...

Luna Rossa did a wonderful job, indeed, and Desafío is holding tight. Crossing fingers.....

 

It was pointed out to me last night that Luna Rossa's name resembles that of my middle daughter, Leah Rose. Perhaps that's my bias.

Is that non-technical enough?

 

I just noticed something in the photo above. Did Luna Rossa borrow Mascalzone Latino's boom?
