Re-Lining the Keel with copper sheeting

I have a 1950's 28 ft 5 ton wooden motor cruiser (no sail) with a gradually tapered flat keel- the original copper sheeting is wearing away and I wish to replace it at the next slip - to do that Iwill have to remove the sacrificial keel, peel off the old copper and replace with new copper and replace the sacrificial keel with new wood - anyone with that sort of experience out there.

The boat lives in SSE of Australia (Lakes Entrance/Mallacoota) and the lakes around there have worms - I replaced some of the sacrificial keel last slip and it was infested with holes made by one worm - MVR

Sounds like a big project, but what do I know. I am sure someone here has done this before. Good luck to you Romnya.
BTW, i love old wooden boats.

Re: Re-Lining the Keel with copper sheeting

In the early 60s worked in a yard here in Bermuda that maintained the Royal navy pinnaces. 52 ft LOD, plumb stem, deep wine glass transom, double diagonal teak, nailed and rooves.
Bottoms coppered with 4 ft square sheets, can't remember the guage, fastened with 1" bronze ring nails on a 6" grid IIRC. Lots of pin punch holes done in place so that the dimpled copper gave a bite into the planking.
I seem to recall coating some plaking with hot bitumen.
We worked from stern forward, and from deadwood up.
These boats didn't have a sacrificial shoe, which was the reason we got to replace the cladding regularly. ( Royal navy liberty launches and shoals don't work together )
We would form up a "U" shaped piece to cover the underside, and up the sides of the deadwood.
The upper edges of this keel cap were finished into a shallow 'V" shaped rebate cut into a suitable plank 2 or 3 above the garboard.
The sheeting was them worked with various wooden mallets and dollies as we proceeded upward and forward.
I worked under a true craftsmen, retired RN "chippie" who built lightships, and incidentally, was on HMS Amythest, the gunboat in the Yangste River incident.

If you love wooden boats see the youtube video L'Hermione en images. A French frigate replica. Now that is one serious wooden boat.
