OK, looking through the archives and so on, there seems to be a LOT of discussion on just what are the rules for transom sterns, references to the British G3 battlecruisers, etc. I'm working on some provisional German CLs for laying down in 1928, and ran across photos of the German CL Konigsberg (launched in March of 1927), which clearly has a transom stern
link here . So, are transoms allowed on CLs in 1927-1928? Could the transom rule, whatever it is, be put into the Design Rules for Gentlemen?
