Small purpose-built cruisers versus armed merchant cruisers

Why choose a small purpose-built unprotected cruiser over an armed merchant cruiser?

It could perform routine naval work economically, support shipbuilding capacity, and remain available without withdrawing an expensive liner from trade.

Small unprotected cruisers could cover anti-slavery patrols, revenue duties, distant stations, and wartime trade protection. A purpose-built naval vessel could remain available without withdrawing a useful merchant hull from commerce at the outbreak of war. Regular orders for these ships could also sustain smaller yards and create local repair capacity in Britain or its colonies. Requisitioned liners, by contrast, imposed exceptionally high fuel and operating costs once taken up from trade. Cruiser procurement therefore affected mobilization planning and the wider industrial economy.
