@ gaelectic: The board is oriented at the Mako
150x40 measurements, constant rocker line along the stringer 57mm, constant concave curvature, depth 19mm in the middle, 12mm in tips.
@ ice1969: for a first project the Mako
is too difficult and will end up in frustration. I'd do something easy like a skim which you can build on a rocker table. Couple boards down you can jump on 3D curves like the Mako
. And it will take you a fair amount of boards and talent to get something as beautiful as John's boards.
