Strip planking is or at least was a common wooden boat building method. Not always covered in glass. It seems similar to our kayaks but not really.

Normally the strips are fairly thin (compared to normal boat building wood), have concave/convex matching shaped strip and are edge nailed as well as glued between strips. Hulls can be built over forms and don't require many if any frames.

Like I said, it's similar to strip kayak construction but not the same.


Here's an example:
I built a 29' Joel White double-ender sloop using strip-planked construction. Joel told me that it was a common building technique for fishing boats in New England and the Canadian Maritimes, generally (in the 'old days') using sawmill offcuts.
IIRC, the scantlings on that sloop called for 1.25" (or 1.375?) thick mahogany (I used Eastern cedar) strips (x 1.5" tall), edge nailed (and epoxied) through into two adjacent strips, with bronze annular ring nails every 6". Square-edged, not B&C.
Not glassed, but epoxy coated - and when I asked Joel, he strongly advised against glassing. On the interior there were no frames but laminated ash/oak 'straps' in the way of the floors. All the interior structures (bulkheads,lockers,berths, etc.) were bonded to the hull with epoxy-fastened cleats. Deck was plywood covered in epoxy and Dynel over laminated ash beams.
The result was a very strong and tough boat - absolutely quiet with none of the creaking of a traditional caulked hull - very consoling on a stormy night.

When I was starting the sloop project, I thought: "I've built a bunch of strip planked canoes; this can't be that different."
I was wrong! :-)
It's a whole different world bending and twisting thick stock.

I think we should be calling our kayaks 'epoxy fiberglass wood core composite' construction. ;-)
