Do a search for the threads from the Chesapeake guys from last year. There were several
techniques that worked well for their boats on lifts. I think the bottom line is get it high and
tie it tight ,as in spring lines . After you secure it. Pictures, pictures, pictures. Then the insurance people can't claim negligence on you're part if there's damage.
Good luck,
A little praying to the pagan boat gods won't hurt.....
