Rollover Part 1: Winch out, slide sideways, and build roll over cage
1) Temporary struts attach hull to cradle. Pipe sections under cradle act as rollers
2) Winch the hull from the garage using the truck as a belay point.
3) Move the truck to the street to get another purchase.
4) Winching the boat sideways. Two winches are secured to eye bolts in the cradle.
5) A sheet of MDF under the cradle is lubricated with dishwashing liquid.
6) Rollover frame built around hull.
Had I been working in the sideyard, the roll over process would have been a lot simpler. The hull is more than strong enough to roll over without any support at all. In that case I'd have just taken out the molds and rolled the boat on her own sheer, letting her flop onto the grass or an old mattress or two. The space I had to work in was too small for that sort of uncontrolled roll, and has a hard surface that would grind the hull too badly. Instead, I came up with this plan: 1) drag the boat out of the garage 2) slide it sideways in the driveway to get the largest possible area on the roll-over side 3) build a box-shaped frame around the hull to keep it from grinding against the concrete 4) use winches and jacks to tip the frame and hull on its side, then the rest of the way 5) disassemble roll-over frame 6) jack the hull up and place on cradle 7) slide cradle and hull back to garage door 8) drag boat back into garage.
