Looking through the forums today I saw a treaty rule that pointed out that I have a serious flaw in my building plans for Atlantis...
Part 3, Chapter H, Article I, no Contracting Power
may retain more than one capital ship due to be disposed of, for
experimental purposes, and one capital ship due to be disposed of,
for training-purposes. No Contracting Power may retain more than two
vessels classed as Cruiser sub-category (a) otherwise due to be
disposed of, for training-purposes. If further vessels of the above
categories are retained in the mentioned roles, they shall be charged
towards the tonnage of the category towards which they were
previously charged.
Currently Atlantis is converting the BB Agamemnon and the AC's Venezuela and Cape Verde to training ships. According to the rules I'm only allowed to retain 1 capital ship for training purposes and 2 heavy cruisers for the same purpose. The problem is the AC's in their current planned conversion are being converted as if they were capital ships which means I have one to many ships converting. Even if classed as cruisers the planned design is also one main turret too many and the caliber is in breach of the treaty (9.2"). When I attempted to solve this issue and redesign the ships in Sprinsharp I discovered a similar problem as when I redesigned the Tyrrhenia class BB's, they are way larger than they need to be according to their capability's. Originally this is what the designs stats were...
Maritania class AC's 1908
Maritania (re-named Lyra in 1916), Venezuela, Cape Verde
Demensions:485/74/27
Armament: 10x9.2"(5x2), 8x6", 4x3", 10x.78"
3x18" torpedo tubes (underwater)

Lyra now a floating museum in Aufidus being in an enclosed berthing and having her machinery and guns incapasitated, Venezuela and Cape verde are decomisioned in preparation for conversion to training ships, Venezuela is in a decrepid state.
Keeping the stats the same (except for speed) Hull strength and stability were way better than the minimum requirements for a good design, therefore I downsized the hull abit and heres what I got...

Originally I wasn't able to keep these ships as they would have rated as capital ships with their guns and displacement, however after designing them in springsharp they have shrunk considerably. There is no logical reason why they should be as large as they are, so with a refit in reguards to armament they could be retained as CA's.
If I did this would anyone have a problem with it? It was definately not my intention to find a way to retain these ships but given the situation I find myself in it would seem it is possible to keep them. Please note my Tyrrhenia class BB's shrunk by nearly 3000 tons after their redesign. If there are no problems I will change the rebuilds currently underway and instead have them converting to CA's.
