Phil,

I'm guessing that you considered vertical movement only, and simplified by ignoring the small vertical movement of the compression strut under bow tow-in. Still, thanks for the calculations.

For comparison, it would be interesting to know of effective it would be to simply have a third bridle between the bow tips straight to the pole (not the tip).

More than 2 years ago, I asked Charlie O' how they liked the Eeeles snuffer (the one used in Athens). He seemed less than enthusiastic about it, but said it provided the best foretriangle stiffness, and they found that that was vital.
So, we know they are worried about foretriangle stiffness.

I was thinking that perhaps the black boat was simply a charter, because

• both of their boats were white 2 years ago, and their Nats boat 2 years ago used
• the Eelles snuffer,
• a different jib downhaul along the bridle to the hull
• a non-cascaded main sheet.

However, the connection to M&M design is strong, since they used custom centerboards at the Nationals 2 years ago designed by M&M and built exclusively for them by WaterRat, and Glaser's loft is near M&M in Long Beach. (Glaser is their coach.) So, they certainly may have painted their boat with the new slick black paint that Pete Melvin is using. It's interesting to see a Glaser jib on the boat, because Glaser is their coach, but Ogletree works for Ullman and I thought I saw all-Zucholli sails before. Maybe they are going all-out for weight savings, and water-shedding paint would certainly help there, assuming the paint itself didn't add weight (old paint was sanded off prior to painting).

The boat in the picture is their boat and is NOT a Marstrom

Glenn,
I kept it simple by just looking at the vertical movement but I did take into account the small movement of the compression strut due to bow tow in.

Regards,
Phill

Where is your unrefutable scientific and demonstratable evidence stating that the boat is NOT a Marstrom? Otherwise this is all hearsay and I have to discount your assertion.

I have a sworn affidavits from Graham Eales, Goran marstrom, John and Charlie, GOD and some random muppet from the beach. All confirming my statement <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

But still I seem to be lacking the science bit....

Better work on getting that then <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

And at least you guys stayed upright on the weekend unlike others.

Ogltree & Lovell were using a Marstrom snuffer with the large solid section:



The Elees snuffer is a two part...standard 2" pole with a carbon/kevlar tube fitting alongside the pole:



If the pictured boat is in fact not a charter, then they must be trying out the less sophisticated ring & bag setup due to lighter weight reasons, perhaps trading off some foretriangle stiffness.

In the light conditions expected for Quidong, it may be the best compromise.

So, if the boat is not Marstorm, then a Graham Elees? What's the advantage for the Games?

Mike.

Jikes, look at all the patches on the Eeles snuffer. An argument for the ring and bag.

Sorry it is Qingdao, not Quidong. There are 2 Quidongs that I know of in China and both are inland and not near Qingdao.

They brew the beer in Qingdao (thanks to the Germans), and that is the most important thing to know as there won't be too much sailing going on I suspect in August.

Yes, I beleive the class rules for T allow down to 2.25 kg for the pole & snuffer setup...My original Guck Snuuffer (all carbon scoop on a Hall Spars 2.25" carbon pole with mylar bag) came in just a little over this. So a full carbon snuffer must be a fair bit over the limit. Not surprising that they are a bit fragile with the builders trying to remove as much weight as possible.

They do bring a better windage profile than a floppy bag to the table...but perhaps this is less significant in lighter airs.

Check that...Qingdao for sailing & beering, Quidong for Blowcart Racing <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

Absolutely. But wouldn't guarantee wind either at Quidong! Go to the beer place instead.
