Project history

The successful multi-purpose boats used as minesweepers, minelayers and ASW boats. Wooden, round-bilge hull. 52 more boats (in the list are not specified) have completed as rescue launches. Canadian ML001-080 have renamed ML050-129 later, that has created some mess in numbering since the part of these numbers has already been used for a designation of boats of 1st series. In the end of 1940 for defence again waited landing of German troops to British isles 60 boats of early series have received 2 533 TT removed from former American flushdeckers.
