could you post a link to the photo. I am able to retrieve the photos from the link i posted, but don't see any from your post.
you now have my curiosity up. Not a PRAM? 8' sailing vessel. I have seen a few, but not Catalina models.
Hope it opens for you. I was just told by Catalina only 2 or 3 were made. The ad says it uses a Laser rig. Since i have 3 Lasers have extra rigs/sails. IF they fit, have not tried it yet, then i only need blades.
