Rob,
I was looking here:
http://www.sailspeedrecords.com/comp...age/Itemid,10/
It seems to be up to date for 2007, the last posted record I saw was April '07. I'm certain it won't be much longer.
There are many different catagories for sailing speed records, from 1/2 km to around the world. Sure enough, Hydroptere owns one of them. The claim is valid.
I own some real estate but I don't sell or trade it for a living. I just thought "location, location, location" was humorous.
