You can only admire the work of Robin Mair, in Hanalei, Kauai, HI.
Mainly surfboards, but it may give an idea or two, on construction methods, art, etc...

Fin options and ideas (he loves quads). Click through the pages for more. Only for the open minded !!

Nice guns !

Flick through, it might help you create something yourself....

And a pic of Robin (on left) part way through a gun.
The thing on the wall on the right is a clever device that can actually measure the rocker curve. Helps to duplicate, replicate, and tweak from existing boards.
