F18 and Tornado Technical Clinics videos

Mischa Heemskerk and Andrew McPherson gave a complete technical talk for the F18s and performance cats in gral, at the last US F18 2010 Nationals held at Racine with a record number of 56 boats, including two crews from Argentina (with an excellent 7th overall for one of them).
There were some days without wind but the organization took advantage of it and now is available online.

For those starting to catsail or just interested in technical info, I can´t tell you how lucky you are as just some years ago this type of data was non existant or not available on the web.
Really excellent job from the Catamaran Racing Association of Wisconsin. www.crawsailing.org
