A cool idea indeed! Helps is your boat exists as a 3D model.Scanning your sailboat is quite possible, but as mentioned above, might be a little ambitious.
Cool idea though.
At work we have a few, and they are encouraging folks to use Blender, a 3D modeling program. Does sound like a bit of work, but interesting.... Note: I laser scanned a bike owns face and machined it in 3-d out of aluminum and he used it as an air intake cover on his Harley. Looked awesome!
