Rigging of cruisers and destroyers WWI/WWII

[Jemiba]

From the turn of the century onwards, warships didn‘t had sails anymore, but often still masts and yards. Most drawings show the yards perpendicular to the long axis of the ship, but for example in Friedmans books about British cruisers and destroyers, they appear nearly parallel to the long axis in the side views, but not in the top views.
So my question: Could the angle of the yards still be adjusted as in times of the sailing ships, maybe to achieve better recognisability of signal flags, or something like this ? Have looked through lots of photos, but couldn‘t find a clear indication.

It is just a way of depicting them in detailed drawings, thereby showing the fittings and aerials attached thereto.

Later in the war some ships carried extra yardarms fitted fore & aft to carry the ever increasing numbers of radio aerials required, usually for communicating with aircraft. So for example various carriers, and:-

Cruiser HMS Royalist fitted out as an Escort Carrier Squadron flagship in late 1943 which operated with 21ACS in the Med and Indian Ocean

HMS Boxer fitted out in 1944/45 as a Fighter Direction Ship with 4 masts and multiple yardarms.
