I wouldn't say they've been curiously evasive...I would say they simply haven't reached their final configuration yet so they could present the measurement certificate. Alinghi has been trying to make it look like they've been "overly evasive" about it but there's historical precedence of the CHR being presented only weeks before the event. The Deed says "as soon as possible".

Word is that BMWO has a catamaran in the shed that we'll probably see sometime in August but only after Alinghi announce the venue for the match. They'll probably trial the cat against the trimaran to figure out which boat to bring to the table. Personally, I'm wondering how they don't pitchpole a catamaran that is 90' x 90' with a length to width ratio of 1:1 AND a bow sprit that extends 40' in front of the bows. Rumor is that Alinghi has water ballast but it could be a sticking point if they have to use combustion engines to fill the tanks.

BMWO took delivery of their new Hall spars mast earlier this past week and it is 6' from leading edge to trailing edge and is at least 180' tall.
