Welp, here we go again. The one constraint this time: new Panamax absolute lock dimensions: 1400 x 180.5 x 60 feet.
Springsharp was used in these loose calculations where appropriate. Note nice fat stern balances the generally aft-heavy superstructure, which is nice and narrow. Without actually doing any math, I am optimistic re: weight and balance. Nice deep hull, heavy reactors, lots of armor... and frankly not enough of the systems are publicly defined to really have a good guess.
