Steve,

Maybe a decade ago this was true, but in the real world of today's
shipyard, the cut files are all done on computer, the plate is burned,
and erection starts the next week. The loftsman is a dying breed.

We (commercial naval architects) seldom provide tables of offsets any
more; just send 'em an IGES file of the 3D hull surface, or we produce
all the steel parts in house. No lofting required.

Aw shucks! You didn't even mention being able to run a ball bearing
along the panel seams before weldup! :-)
