Quoted endurance is 2,100 nautical miles at 20 knots, initially qualified as theoretical. The forward bridge and gun arrangement are blamed for excessive forward weight and top weight, producing pitching in rough seas. Extra forward ballast intended to counter the bridge's top weight worsened the problem. A personal modelling exercise suggests moving the superstructure and forward guns aft towards the first funnel, incorporating the funnel into the superstructure. The suggested improvement in seakeeping remains a modelling proposal, with no historical alteration or full-scale trial claimed.

Leningrad's forward weight and a proposed rearrangement
Bridge and gun placement are blamed for poor trim and pitching; moving them aft is offered as a modelling proposal.
