Or get a lathe

Yes, that's right. Just to complicate matters, they're often curve-tapered, if you like, rather than being a conic section. Entasis is the architectural term.

They use a copper clink - like a nail that gets driven through the boards and is clinked in situ?. The smaller boats (fourareens - or 4 oared boats) are used for sailing in regattas up there still - they are based on old Viking boats I think. Traditionally they were built from larch or oregon pine but a lot of the new built ones are (or certainaly were when I still lived in Shetland) made of fairly thin marine ply boards, clinked up and were often coated in west systems epoxy from memory.
Always wanted to build a boat, but my Wife is not keen on the sea at all.
