Well written, and very amusing in places, it is shedding light on some of the lesser known (to me at least) aspects of late 19th and early 20th century naval design. Particularly for navies other than the Royal Navy and United States Navy that you don't often see written about.
Particularly amusing thus far has been the criticisms levelled at Jacky Fisher's brainfarts (aka a certain Battlecruiser concept...) and a 1930's exchange between the RNs Directors of Naval Intelligence and Construction.
The DNI was criticising the DNC for not matching the performance and armament figures of the Japanese Furutaka cruisers.
The DNC retorted that either the figures were incorrect, or the ships were made out of cardboard.
