Initially, requisitioned <a href="/wiki/Fishing_trawler" title="Fishing trawler">trawlers</a> were used for the task, but they had too deep a draught to operate in some areas, and could be too slow to sever the mooring cables of the mines.

They were significantly faster than the trawlers and had a shallower draught. Although unable to operate in rough seas, they were judged to be the best solution to the problem and a requirement was issued for a purpose-built class based on the <a href="/w/index.php?title=PS_Glen_Usk&action=edit&redlink=1" class="new" title="PS Glen Usk (page does not exist)">PS <i>Glen Usk</i></a>, a Bristol pleasure steamer.
