There is a book referenced on a few websites that I haven't come close to finding. I've seen it called a few things. I can't find a title that I can reliably search for.
Fujian sheng yuchuan tuji (Collection of Fishing Boat Drawings from Fujian Province) 1962, Fuzhou (Fujian Peoples Publishing House)
Atlas of Offshore Fishing Vessels published by the provincial authorities of Fujian.
