OK, you just reminded me of a story I read by Hobie Gary... he posts on this site and beachcats group at yahoo regularly. He does several Catalina trips a year where he has had to use a winch to pull his Mystere6.0 far enough up the beach so it doesn't wash out with the tide. You could try contacting him or look up some of the past article in the e-zine "On the Wire" about some of his trips.

Gary... you out there? Any ideas?
