Hi Cossacks,
If I learned anything from building HMS Diamond a slightly more modern Daring Class Destroyer you always need good access to the works for oiling and running repairs, so Cossack is having a large section of the rear decking removable, which will include the rear superstructure, AA platform, torpedo tubes and the rear funnel, easy to say but keeping the deck camber maybe a challenge, we will see 
I have cut up and painted 1/4" steel plates to fit inside the base of the hull to put 5 lbs of ballast in the best place, then the decks will be glued in place.
Eddie and I are meeting up on Sunday morning to compare notes and hulls at the Chantry MBC's tug day at Bluewater Shopping Centre.
Regards Ray
