2 engine cranes??
One on the front lifting from the anchor/winch rope eye and one on the back lifting a sling (with a loop in the middle that goes in the hook of the engine crane) with the ends connected to the ski hooks.
Once lifted rotate and lower.
Or the footy team....
Or how big is the rotisserie on the BBQ??
Personally, I'd invite a few mates for a BBQ and once they're there use them to carry the hull out into the front yard, flip and carry back in.
