    Takao, Very helpful answer, thank you. I was off course, and you have steered me back in the right direction.

    I appreciate everyone's answers. In case of interest to anyone, I had been looking at French pre-WW2 graving docks, and here is what I have found so far. Should be fairly complete for French navy operated graving docks, but probably very incomplete for commercial:

    Port Dock, Type, Dimensions, Military/Commercial
    Brest
    Laninon Dock 8, Graving Dock, 250x36 m, Military Dock
    Laninon Dock 9, Graving Dock 250x36 m, Military Dock
    Pontaniou No. 2, Graving Dock 178x27 m, Military Dock
    Pontaniou No. 3, Graving Dock 178x33 m, Military Dock

    Cherbourg

    There were a thread or two over on the Axis history forum that went into details about the slips available to some of the powers prior to and during the war. Not directly related to the above but you might find them of interest.

    So long ago, I'd forgotten about it.

    As @GJPBoston noted, the drydocks at Brest were 250m long, which is probably why the Richelieu class battleships were 248m.

    Bismarck and Tirpitz were 251m, one meter too long to be docked at Brest unless they squeezed them in on an angle as in the photo @Takao provided. This is what made the Normandie dock at St. Nazaire so important.
