Poniżej dwa zestawy rachunków ze Springsharpa dla krążownika proponowanego przez Kpt. G.
Pierwsze wyliczenia są dla wersji "podstawowej" przedstawionej przez pomysłodawcę z napędem silnikami Diesla.
Natomiast drugi zestaw jest ze zmienionym zestawem działek 40 mm i napędem turboparowym.
Miłej lektury.

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,556
Length to Beam Ratio: 9,38 : 1
'Natural speed' for length: 22,18 kts
