Rolling Keel Lifter

Last fall I fastened two 30" by 19" 1000lb capacity hardwood dollies together to make a rolling keel dolly. Dropping the keel into it and rolling it from beneath the boat was a piece of cake, but rolling it up on to the trailer with a come-along was a pain, and I wondered how re-attaching the keel would go in the spring after I refurbished it, considering I would probably be doing the chore single-handedly.

After I refurbished the keel, I added a 2.5 ton capacity scissors jack to the dolly and used a portable trailer winch to load and unload the keel into my rented U-Haul trailer. Since the boat yard is gravel, I placed plywood down to give the dolly a smooth surface. The keel rolled easily into position, and then I used CloudDiver's suggestion to use long threaded bolts or rods where the keel bolts go, to guide the keel into position. Once that was done, I just cranked her up into place, removed the long rods, and installed the correct bolts.

She gets bottom painted tomorrow so the keel will match the hull.

RJD, do you still have dimensions for the rest of the sled apart from the dollies? Please post??? I have located a keel for my boat (#10628 an '82) which I hope to have in my possession soon. It will be the first thing I tackle other than degrunging which is already sporatically underway.

Thanks

Geoff

Geoff, that's good news!
Here they are:
-2 by 4s
Two lengths - 70 inches (connecting the two dollies)
Two lengths - 24 inches (forward uprights)
Four lengths - 20 inches (middle and forward uprights)
- 4 by 4s
Three lengths - 19 inches (bottom base supporting the keel)
Six lengths - 8 inches (top of the base straddling the keel and keeping it in place)

Good luck and keep us posted on your progress.

Beautiful work! Looking over the "working" pictures, I'm wondering what kind of winch is that in the trailer you're using to haul into and lower out of with? Where did you get it? Also did you shape the keel as per the template (13% foil shape) given in the CD keel video?

Very nice! Just wondering why you didn't paint the keel and bottom with AF first before you installed the keel....or did you remove it again to paint? I was unable to paint the very top of my keel or the keel slot with the keel installed.

That's a Haulmaster trailer winch from Harbor Freight Tools - 900 pound capacity.

I used a NACA 15 airfoil as a template for the keel.

I had the marina do the bottom paint after I installed the keel.
