BYMS, British Yard Mine Sweeper were all built to the same design. The only variation was one of appearance in the number of exhaust stacks. Note, the Acoustic “hammer” on the bow in the up position used to sweep for acoustic mines and the drum on the stern for the LL cables used to detonate magnetic mines.

BRITISH YARD MINE SWEEPERS
BYMS’s were built in the United States and transferred the Royal Navy under the Lend-lease Programme. “British Yard Mine Sweepers” are so called because they were built to the same design as the US Navy’s “Yard Mine Sweepers”.
Crews for the BYMS’s would sail to the United States, often on the Queen Mary, which could sail unescorted because of her greater speed, to collect their vessel. They would then have the formidable task of sailing their small vessel
back across the Atlantic Ocean, often in winter.
