With the help of the hull profile plans I can determine the X, Y, and Z
coordinates of the hull. X is forward-backwards, Y is up-down, and Z is
left-right (or port-starboard). I start with a plane I subdivide when necessary.
In that way I work down the hull. When exporting to obj-file I (well, blender)
triangulates those rectangles. You see the result, quite convincing.
I have mirrored the hull, added the keel, which are povray objects from
roundedge.inc.

Cheers
Ton.
