DA: His specific naval rating prefix, standing for Deck Hand in the Royal Naval Reserve (RNR) Trawler Section.
As a Deck Hand with a "DA" registration prefix, Charles Burn was a professional fisherman or merchant mariner mobilized into the Royal Navy.
He served aboard requisitioned commercial fishing trawlers and drifters.
These small, wooden, or steel-hulled civilian vessels were fitted with small deck guns and used for the incredibly perilous work of mines and anti-submarine patrols along the British coast and the English Channel
