There is not as much weight information for WWI destroyers as I would like to see

The definitive book on British Destroyers (March) is sorely lacking in the sort of data that we need to be able to design WWI-era destroyers. That is not to say that there is none, for there is a bit. There is just not the breadth of data that would need to design a range of destroyers (large and small, from 1905 to 1921). D. K. Brown generally doesn't have that sort of data, either. He is more concerned with what I would call "structures".
