Hello Ashley
Thank you for the very kind offer but I have a copy of D K Browns book.
I have looked at the development of the first class cruisers from Warrior to the Dreadnoughts and the problem is that the science of hydrodynamics was developing so fast that each new design changed as the cruisers developed, even the Drakes that were a direct development from the Powerful class were substantially different from Powerful and Terrible.
I could make a guess as the underwater profile but I don't want to do all the work only to be pulled up by a rivet counter.
I am registered as a researcher at Greenwich and have been through their archive but with no luck.
So you can see the problem.
Perhaps I should build HMS Leviathan instead (a Duke class from 1901)
Just fed up but thanks for the offer.
Paul
