Rolling Over A 30' Boat Hull

[Skiff Builder]

Original plan was to pull the building jig/hull out on the driveway,roll it, pull it back in line ,than back into shop. Gravel driveway-this takes a bit of timber and time.. I have seen some complicated rigs/wooden rolling wheels/boom trucks/construction equipment and/or a lot of people used to accomplish this.

It's off season,no ones around and I don't have a fixed work sched I can count on, to set things up. Need to go simple/basic and probably solo on this.

Talking 20-3/4"ply
12- 1/2"ply
30 gal epoxy, 60 yds cloth, 2 gal epoxy paint, etc.
Minus cutoffs/waste.
^2200 lbs estimated.

do you have a cradle built for it?

If someone was building a huge boat in a tiny garage here in Indy, I would be totally "on board" (get it?) for a boat-rolling party some Saturday or Sunday. I don't even like boats. It would just be interesting.

Maybe there's a way you can recruit and wrangle enough people to get this done safely? It would cost you some beer and/or coffee and donuts. Maybe have a nautical themed cookout?

Short of renting a Lull or small crane, I'm out of ideas but that is cool as hell that you are building a 30' boat in your garage. The wife and I have talked about building a 20'-ish for years. What whill it look like when finished?

 

[The Cobbler]

get some trailer axles and & wheels under it so you can move it out.
hoist it up & tip it over ( maybe a wrecking truck?)
roll it back in
in any event, you need help, wood & equipment

 

[mz44]

A tow truck with an extendable boom, Or try a crane company, they may have a small boom truck that would work. Probably cost a few hundred though.

The boats beam is 8'3". Ceiling is 9'3" minus T-8 light fixture and bulb.

I have not installed the uppermost plank (wale-in brown in pic) at this point. That leaves the shear clamp (5/4 x 3) exposed during the roll- don't want any pressure on it yet.

Been two months/ 100 miles away from project working straight doubles /7 days/wk with one or two half day breaks. A lot of time thinking of ideas like you guys have above.

Supposed to look like pic below when done.

Cradle will be four or so 4x4 run athwartships under the box keel, short props with pads against hull.

 

[SGKent]

drag it out, build a 32' long doughboy pool around it out of plastic and sandbags, fill with enough water to lighten the hull, roll it over onto the keel sitting on sandbags to cushion it, build the cradle and cut the sand bags to lower it down onto the cradle. Roll back into the garage, haul away excess sand and done. You can also tie foam to it so it doesn't just roll over, fill with water and sink.

Other than that a crane will be needed. Be sure the lift points won't collapse or warp the hull.

Very cool project. That is going to be a nice boat. What does that hull weigh?

Other than a tow truck with extendable boom to lift and move it, I have no other idea. If you have AAA with towing service, maybe the driver will help you out for a few extra dollars. It would be a good story for him to tell his buddies.

Good luck with the project.

You can roll a lot of heavy stuff, Egyptian-style on 3" -Schedule 40PVC. Although on gravel its going to be a slow go. If you had extra ply you could build a "road". I am not sure if your internal frame is setup for that, though.

Are you planning to roll it over with the hull touching the driveway? It could probably be done with a couple of lever-chain hoists and some hard points to hook them to (large tree trunks, could be the trailer hitch of the Yukon) Basically one with rigging over the keel hooked to the (? term = edge of hull like where you'd place oarlocks) to start the roll and then another for "braking" or "spotting" as you cross over center so the keel doesn't slam down. Would definitely need to protect the (? edge) from the gravel with plywood to avoid scuffing it.

Going back in could use the rollers again but it looks like it would be super unstable on the narrow keel when uprighted without some side-bracing.

If you had a hard point in the shop and didn't care about the cradles you could simply drag it with same lever hoist, 1 inch at a time, intense bicep workout for some hours. Would need cable or chain or rope to make sure all of the cradles move in unison and not just grab the forward one out while the rest stay put.

Some people have cooked up their own "air skates" to float heavy stuff around on concrete (think air-hockey in reverse more or less), and the general idea sounds applicable to you, except I think on a gravel drive it would be a non-starter. Maybe would work with the plywood "road" but I'm not sure what kind of air compressor flow you need to handle this...bigger is definitely going to be better, especially as you cross gaps and "steps"!!

The only thing that comes to mind is to strap it to a frame rotisserie.

Trying to get this all posted while at work- reason it's fragmented. Again all great suggestions on rolling. In the end I had one day to get this done. My wife was on hand as Chief Photographer/Safety Officer.Stopped by Lowes and picked up bundle of cull wood for $31.00.Chain hoists/straps/bolts on hand in the shop.
About 2 hours to setup the roll jig and prep.

I would lay down some 2x6 runners. Get the hull up enough to get 3" pipes under it and roll it out on the pipes. Make a cradle, easy now that it's upside down. get it flipped on to the cradle and roll it back in.
Shouldn't take more than an hour or two. And if you believe that........

 

[Skiff Builder]

The thing is getting the two bolts placed at the right height on stem and transom, so hull is balanced well for rotation.
Climbed under the thing and undid all the bracing and connections to the build jig. Took apart the build frame and slid it out for max vert clearance.
Had a belaying line around the hull.
It balanced really well, never took more than one hand to move it. Adjusted the fore and aft chain hoists as needed throughout the roll. Went slow and easy-about 15 minutes and done.
No creaks or groans from the skiff. I did take out two T8 bulbs- the only real excitement.

 

[dirtrich]

Very impressed!
Beautiful boat, and clever solution.

 

[BajaScout]

Wow! That is quite the feat. Too bad you did not do a video.

[The Cobbler]

great job an all counts!

 

[Slowboat]

Awesome!

 

[bad_idea]

Wow. Awesome work.

 

[66Caprice]

Sooo you didn't really need our help or ideas. You just wanted to make us all envious of the beautiful boat you are building! You have done it! I say this and I am sure alot of others on here will agree. Please continue to post up your progress!!!

 

[bwringer]

Welp, I didn't see that coming. No idea you had juuuuuuuuuuuuust enough room to do this in situ.

Very well done. Keep posting pics. That thing is going to be awesome.

 

[ford33]

Wow. That was something to see. Nice work.
Keep posting your progress. It will be interesting to see how this build progresses.

 

[K'ledgeBldr]

Call Gibbs

How did he get that boat outta the basement???

 

[matt_i]

Great job there, I didn't realize there was enough room to roll it inside

What kind of power source is this going to get? Diesel, outboard. gasoline "V" engine?

 

[K'ledgeBldr]

Nice picnic!

I've always had a thing for classic barrel-sterns...

Beautiful boat

 

[mikegt4]

Parker Sea Bright, he designs and makes some nice boats. I use to stop by the marina were he built boats and saw many of his projects.

Nice job on your project.

 

[Glaffer]

That's pretty cool. Oh, the boat is TOO! ��

 

[Skiff Builder]

Yes, this is a Reuel Parker designed SeaBright 29.5.

It's spec'd for a Yanmar 4JH-4HTE diesel of 110/99 hp. These hulls are fairly easily driven.Looking to get 15-17kts out of it.

Option B-Outboard Power:I spoke to Parker about placing an outboard in a well just forward of the transom. He gave the ok, but did not have time to design. I can do that.Need to keep it as light as possible for hull balance. The lightest 115hp right now is the Yamaha 4 stroke.About 370-400lbs. I have a Yam 90 2 stroke at 269lbs but need to calc speeds with that hp.

Option C-Gas Inboard: Merc 130hp gas inboard.

Lots of decisions to be made during a build.
Got the hull leveled and braced for the interior fitout.
Did video the rollover-need to edit 15 min down to 1 min as it's not exciting to watch.

A lot of ideas you had while building the hull change once you roll and get inside for the first time.

Some specs pictured below.

Dude, this is so awesome and I'm not a boat guy. I love the cleat on the vertical garage beam.

Now that's a legit use of shiplap.

Tune in tomorrow to see the engine installed!

Do you have a link to the 1 minute roll over video?

Thanks

I am having trouble editing in Windows Live Moviemaker-will post when worked out.

Awesome! I've got a friend in Wildwood (bayside) - when should we look for you on the water?

Well done.
