May I ask you a question ? we could not clearly see the details on the top mast for the SMS Derfflinger ship ,so can anyone tell me which drawing is corret on the picture ?
That is a good question. On a photo of Derfflinger I find the foremast has the yard arms angled forward and the mainmast I can not tell due to the angle. A photo of her after Jutland shows clearly angled forward on the foremast, again the mainmast can not be seen.
These yard arms on German BC's appear moveable. Both in an up and down and in a fore and aft direction. Some examples of other German Capital Ships.
Freidrich der Grosse: foremast: angled aft / mainmast: angled forward. another of the same vessel shows them both with no angle to the masts. Clearly this means they were moveable and not always in the same position.
Markgraf: Foremast: angled directly aft. Mainmast: angled slightly aft.
Seydlitz in a fine profile picture: Foremast: angled slightly aft. Mainmast: angled slightly forward.
Various Light Cruisers: many different positions are shown, even on the same ship
So clearly they were moveable and kept in various positons. But it seems common for the foremast to angle back and the mainmast to angle forward.
