Hoisting and rolling over

[Greg Luckett]

Okay, I have tried searching here for the last hour without any luck.  I know that I have seen pictures of frames for rolling over a boat hull here in the forums in the past.  Can someone point me in the right direction?

Thanks

Thanks Andrew!

Not quite what I had in mind, but interesting non the less.

Charlie Jones uses a couple of hoists in his shop, and pulleys and line wrapped around the boat.  This would work for me, but I do not have a shop to do this in and must build a frame of some kind to attach the hoists to.

What about borrowing a couple of engine hoists - depending on the size of the boat you could put one at the bow, one at the stern, lift and turn.

On my Weekender I installed a solidly mounted eyebolt at the stern for just such purposes.

I copped these pics off somebody's build blog at some point in the recent past. I guess it's okay to post them here.

Another good idea, thank you. Something like that might work for me except the boat needs to be raised higher than that to clear the trailer or frame it is sitting on.  My Spindrift 12 is not hard to roll over with jus the two boys and myself, but if I do a bigger boat, such as a Core Sound or the Princess Sharpie 26, it will definitely be needed.  Maybe a lower build cart or raise the cranes onto a stage?

Yeah!  This is one of the ones I remembered seeing before.  Thanks!

A few beers as a reward and several friends is the fastest and least costly.

No beer until afterward, right? ;D

Your choice, but if your friends are remotely similar to mine, then yes, no beer until after the boat gets flipped.

If the height of the trailer is an obstacle you can always take the wheels off...

This is true, but my objective is to lesson the labor need and improve both the safety and convenience of rolling over a boat while working on it, preferably single handed.  I think the frame with the hoists and ropes wrapped around the boat is going in the right direction.  One person can hoist and rotate a boat this way.  I need to come up with a good frame system that can be easily erected and taken down, preferably single handed again.  Thanks to all of the help and advice from each of the folks here, I now have a good idea of what to make.

Thanks all,

Greg

Post pictures when you're done!

On my last build I found the need to roll the boat several times and also to help work in the down hand position for finishing and 'glass work.

I made a cradle under the boat, that allowed it to flop over on each rail, which placed the bulk of the bottom about level. This made the finish work easier.

The first image is the roll over which was done with a block and tackle. The second has her flopped over on one rail, viewed from below.

An interesting idea PAR, but how do you get the shop on its side too?

[Ken_Potts]

I bet the shop has a really big cradle and block-and-tackle...

PAR's got the right idea in that first photo of his:  Just rotate your whole shop...  ;D

I used the same setup they used on that Fred Estare (SP?) movie where he danced on the walls.
