I see that. It was working 2 days ago. I can still get to the plans from going to the main site and just looking around it. Don't know why the link doesn't work.
Anyway, go down the main page to Radio Control Ship and Boat Plans - Free Download and click on that. Then go down that page to Ship Videos Here - Free Sailing Ship Plans and click on the Free Sailing Ship Plans.Then go down that page to the America Yacht and download the pdf file.
