Krążownik
pancernopokładowy dla francuskiej MW, zaprojektowany zgodnie z
założeniami Jeune Ecole. Przeznaczenie - rajdy na wrogich liniach
komunikacyjnych. Niestety, wynik nie do końca odpowiada oczekiwaniom -
zasięg i prędkość pozostawiają sporo do życzenia, trzeba było też
ograniczyć pancerz i uzbrojenie. Wygląda na to, że do osiągnięcia
zadowalających parametrów przy poziomie techniki z początku ostatniej
dekady XIX w. potrzebna będzie jednak sporo większa wyporność..

Roll period: 10,1 seconds
Steadiness - As gun platform (Average = 50 %): 85 %
- Recoil effect (Restricted arc if above 1.00): 0,15
Seaboat quality (Average = 1.00): 1,71
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,556
Length to Beam Ratio: 8,78 : 1
'Natural speed' for length: 18,44 kts
Power going to wave formation at top speed: 47 %
