Trawlers could be built with much greater rapidity than destroyers, and trawler builders who could not build destroyers could be employed for the work, thus supplementing the activities of the yards which could turn out the bigger craft.

I see trawlers fishing and mine-sweeping whenever I raise my eyes from my writing.

She's the derelict you chartered north of Flores outward-bound, She's the iceberg that you sighted coming back, She's the salt-rimed Biscay trawler heeling home to Plymouth Sound, She's the phantom-ship that crossed the moon-beams' track; She's the rock where none should be In the Adriatic Sea, She's the wisp of fog that haunts the Skagerrack.
