For those thinking a displacement powerboat might be a good move going forward (mean as they get older) here is renovation by Boty at present.
Nice,
But what do you call the planking? Its not clinker, not (typical) carvel. Maybe carvel with something else (softwood?) added to the seams. Carvel-plus?

Could it be splined carvel? 
Not originally splined.
Now splined, so traditional carvel otherwise
Splines not yet trimmed.

Agree with Bob, originally carvel, it has been splined in the restoration replacing the caulking. I think with this method it is normally encapsulated in epoxy /dynel or fibreglass as there is no caulking to take up the expansion and contraction as the moisture in the timber changes.
I'd be interested in how successful this method is in bringing back to life a old carvel hull. I suppose if the encapsulation is done right, it ends up similar to a strip planked boat.
A few weeks ago there was a superb old motor sailer on the slips. The hull had been splined with epoxy filler instead of the normal timber strips and sheaved in epoxy and cloth. The finish was excellent.

Not encapsulating, not a fan of that at all.
The soft spline takes up expansion and contraction.
there are many carvel boats splined at original build.
Here the caulking was original and 50 years let so it all needed to come out anyway.
This one was splined since new, celery top planking and no sheathing.
As far as I can ascertain the 1963 AWB were woven glass epoxy sheathed to the waterline from the build, not sure about the material used for the splines. Wheel house & coach house manufactured from ballistic resistant material. And very similar lines to the head line boat. ( hull speed 9.5 knots can be achieved with a DD 471, light ship )

They had a copper sheet to the waterline.

My old old boat, ex Doreen is down the bottom of the page.

Yes that was the WW2 spec. From conversations I've had the small run of boats built in 1963 - 64 used modern materials, or perhaps it was epoxy sheathed while in service ? either way a 1st class job. The boats with that particular wheel house arrangement where done at the Phoenix boat works Launceston, I've tried to get more info about that yard and the AWBs they produced to no avail, perhaps the brains trust may be able to shine a light ?
