Yes. I'm using a slope map to make the planks.
I use this normal (remember I work with Moray so Z is up,
if you wanna use it with pov coord change it to Y):
normal
      {
         gradient z , 1.0
         slope_map
         {
            [ 0.0  <0.0 , 1.0> ]
            [ 0.05  <1.0 , 1.0> ]
            [ 0.95  <1.0 , 0.0> ]
            [ 1.0  <0.0 , -1.0> ]
         }
      }
Then scale it to fit the size of the planks you want.

For the boat, I had only one half of the hull, the other is
a reference. So I had to rotate the texture to get the curvature
(-20*x. The boat is aligned in the x axis)

Hope this helps.
