Rib Flipping Techniques

Seeing just how good the hull of the Macmillan Rib looks after flipping and all the work that went into it got me to thinking about doing it on my Rib. And looking at the chine damage I've got, it would be worth doing.
However, I've been to Biffs place and can only dream of those facilities - the perfect Man Cave if ever there was one. I don't have a barn or the lifting gear - yet.

I did it on an SR5.4 a few years ago, but it was a bare hull and wasn't exacly easy even with three of us.

For the more normal level of DIYer, has anyone ever flipped a 7mtr Rib and how did you do it?

Engine Off, Tanks drained, what next?

Ok, here goes, if you're doing this in a garden pick an area and make sure it's free of sharp object, you will need to take the console off and anything else that sticks up above the tubes, you can do it with them attached but when you flip it you will need to keep it of the ground by that amount, that bit ain't so easy.
Lets say you have got the space clear and the boat bare, push it off the trailer, onto something soft, but that don't matter too much at this stage cos you're going to do the work anyway. You got the boat on the floor, let down the tube on the side that you are going to flip over, by letting them down you won't have to get the boat so high.
This bit is the bugger bit. You need to lift the boat and you will need some burly gents to do this, there's no weight in the front end so all alone the side towards the aft, this bit is a bugger, there is no hand holds to get hold of, as you push this up you will feel it getting lighter, this is where you need to be quick, find the balance point and get round to the transom and hold it there, all your burly gents need to get round the other side and then lower it, job done.
Sounds complicated but the flipping bit should take you half an hour.
You could use tow ropes etc but you have less control and usually more damage. Hope this helps

I was a bit more brutal with mine, but it was being re tubed afterwards ,

Sling front and rear , then pulled with fork lift turned over on a pallet, this enabled me to move with ease afterwards,

Can you prop it up (substantially) on its side?
No need to take everything off and you could always do it the on the other side after if there are bits you can't reach.

You could do, you need to keep an eye on it though, if the tubes loose a bit of air it alters the angle of the props, it will usually fall the right way up though

I flipped my bare 7m hull. It took just 5 or 6 burly college football players, you have burly rugby players there, a pizza each, and a 8-10 junk used car tires i borrowed from the tire store. I live in the town where I went to college and played football there so I had an in. I built some supports out of 2x12 for the middle and bolted some plywood on the transom that I cut a nice arch to roll it on.

I didn't get any pictures or video of the flip but here is the result. I ended up building a little trolly out of steel 2x4 tube that I had laying around. It's a heavy hull and destroyed furniture dollies you see here. I still didn't get tough enough castors on the steel dolly and it wrecked those too but I got it moved.
