Byzantine Empire 1933-35

[Jefgte]

Since the forecastle is 7.44m-9.09m, not (12-5) = 7m, it is not a flying off deck.

=> it is not a flying off deck.

The quarterdeck must be the same as the flight deck, 12m in this case.

=> Misc weight 6980t was 7200t

[Kaiser Kirk]

thank you for working through that with me.

[Jefgte]

thank you for working through that with me.

Sorry for the inconvenience.


25000t is easy to plan in $ & BP.
