In this episode, Leo drives the 3000 miles back to Tally Ho from South Georgia, where Steve Cross has been milling Live Oak for him.

Leo beds and bolts the 6’ Scarph in the new keel timber together, and the Live Oak arrives by flatbed.

Then they create a framework inside to boat to spread the load of the props while Leo removes the Keel Timber from underneath it, all the while hoping that nothing breaks and that the boat doesn’t deform at all in shape.

It may be worth mentioning that there are three main components to a keel arrangement like that on Tally Ho. The timber Leo is replacing is "The Keel", but below that hangs a heavy "Ballast Keel", which in Tally Ho's case weighs in at around 5 tons (IIRC) ... unlike a modern fin-keeled boat, this ballast keel is a shallow shaped block that runs roughly half the length of the boat and has fairing pieces at the ends called "deadwoods" (because they're non-structural). The third major piece common in this arrangement is the "Keelson", which is inside the boat and forms a reinforcing backing to ther keel, though not all boats have a keelson ... I'll have to check the drawings to see if Tally Ho has one (I'm in England, far from Tally Ho).
