I noticed the Kettermans mixup but didn't alert the dealer.

Membership is free on the Windrider Yacht Club forum. It's not the factory forum; just a few of us owners and kept up by an owner in Ohio.

All that's required is a bogus name and a password of your choice. A few of us toss the webmaster ten dollars or so once a year to keep it flying but it's totally voluntary. It only takes $90 p/yr to keep the server up.

I know the Rave forum would welcome any other foiler skippers; monohull, multihull, Rave or not.
