I just bought an American Fiberglass Corporation A16 and the boat is
in fair shape (mostly aesthetic stuff) but the trailer is in sad
condition.

I thought that if I could remove he boat from the trailer and put it
down on stands (movable prefereally) in my garage, I could then
rebuild the trailer.

I borrowed a chain hoist from a friend and the plan was to hook up the
chain lift to the beams acoss by garage, lift up the boat with a
couple of straps from the trailer (boat weighs around 550 lbs), move
the trailer out, put the boat back down on a some home made stands or
framework.

I need some plans or ideas for making these stands. I'm a decent
woodworker and I don't want to reinvent the wheel if I don't have to.

Thank you

Peter
