Go on YouTube, they show many people flipping Custom Carolina boats and you can watch how they do it. Some use tires and some just cranes with two cables and hooks. The bad thing is once you get it to the point it will balance and want to roll it over past that point it will want to flip over fast. You almost need one crane/lift to lift it up and pull it over and a second one to catch the weight and then lower it down.
Watch these back yard guys do it: They have rocking back ground music too!
