Shipboard maps helped wartime recruits find their way

Maps and diagrams became much more common around ships during the Second World War. Mass mobilisation brought aboard sailors who had little or no previous naval or merchant-marine experience. Diamantina was small but densely packed, with subdivision, duplicated systems, electrical spaces, and narrow routes that could confuse a newcomer. Posted plans let recruits work out their own routes while learning the vessel. The fittings show how ship design and training practices adapted to a rapidly expanded wartime crew.
