105 feet class - minesweepers

At the start of the war, the immediate need for a large number of minesweepers was remedied by requisitioning a large number of fishing trawlers and drifters. They were suitable for use against moored mines, but not against influence mines. The most widely used variant of the latter was the magnetic mine, which detonated when a (steel) ship of sufficient size passed over it. The Motor Mine Sweepers were made of wood, which caused no magnetic field to begin with. These ships were equipped with LL-sweeps against magnetic mines and Hammerblocks against acoustic mines. Cheap, quick to build and using limited resources, a total of 278 were built during the war.

The Netherlands Navy acquired a number of these ships, and named them after Dutch islands. The new ships were manned largely by the former trawler crews, composed mainly of militarized fishermen. They performed well, operating from Great Yarmouth and Harwich in the 139th Minesweeper Flotilla, and later off mainland Europe. After the war, these ships spent some years clearing the North Sea of mines.
