flipping a hull

[oops!]

im posting here in general, for basic info and tutorial purposes. for all new members and viewers not signed on yet.
a more detailed instruction can be found in resto......

easy way to flip a hull....

i dont suggest this be done with a motor in the boat.

place boat between two trees
(im using a deck truck with electric winch and a fork lift. but two trees and a come-a-long will do just fine)

attach a line to the bow eye.....

and a line to the transom eye hooks....(im doing a resto, and i just bolted a single eye hook there for this flip .(join a line between the two, and then hook on to a mainline.....kinda like a ski rope)

pull tight........the balance point between the bow eye, and the transom will determine the ease of the flip.....get the right balance point, and you can flip it with one finger.

the cap is off the boat. but a hull can be flipped with the cap on

a much more detailed version is on the "hull extension in progress with pics" thread in the restoration forum.

the hull flip is used for major bottom repairs, most easy scrapes and scuffs can be fixed right on the trailer.

Re: flipping a hull

4th and 5th pics looks like the hull is bending a little on the bottom! Is it ok? If you look at where its touching the pavement its bowed in a bit. Thats got to do something. Thanks for the info though! Thats just how im going to do mine now, only im not going to use a rollback and a forklift.

the flat bed was not high enough. the flex in the hull side was not crutial, as it was only like that for a few seconds.

the optimum is to have the hull high, at full suspension, so it does not touch the ground......

Re: flipping a hull

I think im going to use 2 trees and some come along straps off of a couple of pully's on the trees. And hook the come alongs together in the center and the pully's mounted on the trees with steel wench cable. Thats a great idea! I can see how you can flip it with just a finger though if you set it up rite. I just worry about the stress on the center of the boat. Thanks for the info!

ooops, you continue to amaze me with your ingenious methods of working out the challenges "opportunities" in your restro project.

Re: flipping a hull

My boat doesn't have a bow eye or a stern eye, what do I do? Actually true and I am not gonna add them, but I would not have thought of that . . . Good plan and I would use that on a hull with both. I would imagine a typical off center stern eye would cause a pretty unbalanced flip. But you could use a typical ski bridle type setup between the two.

Re: flipping a hull

I like that idea but I don't have any trees.

I flipped mine in the garage.

Re: flipping a hull

I flipped one over at my shop using a swivel and cable attached to the bow eye and anchored to my fork lift, and four guys to lift and turn the boat at the transom. We sat the transom down on the dolley and let the fork lift down last. We did the same when I was all done working on the bottom. The boat was only a 17' V hull and not that heavy, maybe 750lbs in all, probably less minus it's upper cap section.

Re: flipping a hull

I quite like your idea. But people can even use another technique. I used it and it really worked to perfection...
