Hi Pip,

The link I published is just a copy of the magazine artikel at the website of 2Bsure. The test and the artikel is done in  2004 in a well know Dutch sailing magazine as you can see at:

http://www.zeilen.nl/tijdschrift/juli-2004/1302

So I think it's a bit quick and dirty analized if you  suggest this is a fake artikel from the manufacturer of 2Bsure.

All the other info I can find on the Seagull IV (also in the links you provided)  is unverified manufacturers marketing (like they are referring to a test from the University of Arizona but the test itself is not published).

Regards,
Mark
