Rolling boat over

[boatrup]

I'm in the middle of my resto. Once I finish stripping everything out of the hull I would like to flip the boat over and fix the chips in the gell coat, and then add a fresh coat over the entire hull.

For those who have done this, how did you manage to get the boat flipped over?

It's a Bayliner Capri 1950

ii used gantrys and 2 4x4 that i used as a shaft and built off of that places to connect to hull then once it was in air i rolled it like a rotissery did all this by myself with no help so i know its possible and it was a 21 ft trophy

I turned a 17' over by myself.----Widow maker on the front trailer eye.-----Made an adapter to bolt on in place of motor.-----Used widow maker on that adapter.

I flipped my 19' sailboat over (1400 lbs) using some straps and rollers supported from my garage ceiling. It got to the point of no return and then suddenly flipped the rest of the way all al once (not recommended).

But there are a variety of ways to do it. The key thing is to support the sidewalls of the hull as they will tend to bear the weight of the hull during some part of the process.

Sounds like some type of rotisserie is the best way.
I think perhaps rather than rolling it over I might just use a pair of engine hoists and lift it as high as I can.
Would I be correct to assume the stern tie down hooks and bow hook are strong enough for that?

I'm also planning to do exactly this over the winter, so really interested in this thread... @boatrup I'd be a little nervous that the hooks would be "strong enough" just until I got myself under the hull, and I might find myself wearing my boat as headgear...

@mickyryan don't suppose you took any photos or could sketch the arrangement up for us? That would be super useful

If you look through posts of my 1989-1990 Bayliner trophy. Thread you should see it I think I took pics when I flipped cap

I saw where a guy used 2 engine stands from harbor freight as his rotissory but I don't remember how he got the clearence needed

FWIW - here are some pictures of rolling my sailboat over of working on the bottom. As the saying goes . . . "Don't try this at home . . . "

I don't know if they ALL have an angle to the motor mounting plate but mine does. Perhaps it's to counter the sag of the weight of the engine... Perhaps to insure an engine doesn't slide out of the stand sleeve when you pull the pin.

Anyways that angle would prevent two stands being used as the ends of a rotisserie. Shop around, maybe there are different ones.

I bet you had a few pucker moments with that!

I’ve seen it done before. Just an empty hull. Literally empty fiberglass hull. Fist they screwed thru the sides 2x4 going port to starboard. Every 2 ft bow to stern. Then they used a crane like device to lift it straight up and then back down bottom side up. Flipped it back the same way. Dependent on boat weight and length a tall tree with a solid branch could work I guess. Backyard theater is way different than professionally done.
