hi all, ive found more news on the RAK regatta, and Alinghi will appeal this.

A New York judge has ruled that Ras al-Khaimah, United Arab Emirates, cannot host the America's Cup based on the 19th-century document that governs sailing's marquee regatta.

The ruling by Justice Shirley Kornreich of the New York State Supreme Court is a blow to two-time defending champion Alinghi of Switzerland. The Swiss picked the Persian Gulf for their February showdown against American challenger BMW Oracle Racing.

Kornreich said her decision was based on the stipulation in the Deed of Gift that the America's Cup cannot be sailed in the Northern Hemisphere between Nov. 1 and May 1, not on concerns by the Americans that RAK was unsafe due to its proximity to Iran

Hi,

I think that Valencia has been proposed as a race venue and the GGYC have until Friday to say ya or na.

Exactly K1W1, that's what's on the table as of right now.

Alinghi's plan to use Ras Al Khaimah, UAE was flat out rejected by the New York Supreme Court. They subseuently went back to the original plan of racing in Valencia in February (which is contrary to the Deed Of Gift) and proposed two alternative Southern Hemisphere venues: Proserpine/Airlie Beach and Townsville in Australia should GGYC and BMW Oracle want that. The deadline for making the decision is this Friday.

Wingmast/Wingsails

* Steve Clark gives an expert view on BOR90's America's Cup wingmast

Steve Clark is widely acknowledged as one of the most astute and most experienced inshore multihull technologists and sailors on the planet. Sail-World asked Steve Clark for his analysis of the largest wing mast ever built.

Steve Clark:' The rig on BOR90 is a two element single slotted wing. This is a 'cleaner' configuration instead of a 'more powerful' configuration. You will not get the high lift coefficients without the #2 element ( the flap in the slot that directs the flow through the slot.) This is probably not a big deal because they have the ability to set head sails for down wind work.

'It may or may not have twist capabilities. For one thing, the use of head sails makes this less necessary. For another, the majority of the wind gradient is in the first 30' off the deck, so given the scale of this wing, it may not be as big a deal as it is for the smaller C Class wings.

'The control system seems to be the tried and true Patient Lady (the predecessor to Cogito) system, which is self tacking and very well worked out.

'The ability of the wing to operate at low angles of attack will be a big step forward for these boats which operate with so much apparent wind. I think it's going to help. If it blows hard enough for them to fly the main hull without the a jib being set, they will be faster upwind without the jib. This was true of Stars and Stripes 88 and should be true here given that this is a very clean wing. Stated another way, this rig will be able to sail longer without being backwinded by the jib. If that becomes a problem, the boat will be faster without the jib...

The entire interview by Richard Gladwell in Sail-World.com:

...then have a look at the size of this crewman up in the rigging....WOW!

America's Cup: Steve Clark on Bows, Stress and Weight

Here are some other good observations:
http://www.sail-world.com/NZ/America...d-Weight/58754

...and note this endorsment




Despite having his skipper and lead designer, Duncan MacLane, from the Cogito project, consulting to Alinghi, Clark can only guess at the development process the America's Cup Defenders have worked through with the multihull now known as Alinghi 5.

'I'm pretty sure that a bunch of the sailing Le Black did over the last year, was loaded to the gills with strain gauges as Dirk Kramers refined their understanding of how the various components of the struts and strings are loaded', Clark surmises.

'I also suspect they tried several different configurations of trussing to determine if there was a better plan. I have a great deal of admiration for Dirk and would hang my ass out a 10th story window on a piece he said was strong enough! So I would probably believe the platform is not going to see the kind of failures Team Phillips and others have seen.'

Hi,

Having spent a couple of years in Townsville working around the waterfront scene I can't imagine a less prepared place for this type of traveling circus.
