Basically, you'll have to have the yard move the boat onto boatstands, like you would for winter storage...then you have to go inside the boat and remove the nuts from the keel bolts... and then the yard will lift the boat off the keel. Make sure the keel is properly braced so it doesn't shift or fall over.

Inspect the keelbolts, since there can often be crevice corrosion, especially in the case of stainless steel bolts, which won't be apparent by a more casual inspection. If the bolts appear to be in good shape, without severe corrosion or erosion/thinning of the metal, then re-bedding the keel may be all you need to do. If in doubt, consult a surveyor other marine professional to evaluate the keel bolts.

Clean off the old sealant of the hull and keel. If the keel is lead, scrub the top surface with a scotch brite pad to clean off any oxidation, then apply sealant to the surface and lower the boat onto the keel...and tighten the bolts to whatever the factory specification is. This will vary with bolt size and is often boat specific.

Some people like to use 3M 5200 for this...I'd recommend using either SikaFlex 291 or 3m 4200. I think that 3M 5200 is just a bit too aggressive.

What am I looking for when I drop the keel? Is there a thread on "properly" re-bed?

Sailingdog, I wish I could download your brain into a book with pictures and diagrams .

You rock.
As for downloading my brain...what a disaster that would be.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
