Motor Minesweeper MMS 59 would have looked the same as her sister ship, MMS 192. 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.
Motor Minesweeper's were purpose built, wooden, shallow draft, minesweepers with both SA and LL sweeping capabilities. SA is Sweep Acoustic, a device similar to a Kanga Hammer which makes a loud thumping noise which exploded the acoustic mine. LL (double L) is a pair of electric cables which are towed parallel to each other on floats and emit a strong electric pulse which generates a magnetic field which detonated the magnetic mine.
Four Hundred and two Motor Minesweeper were built for the Royal Navy between 1940 and 1945.
