From Wikipedia, the free encyclopedia
The Jan van Amstel class was a class of nine minesweepers of the Royal Netherlands Navy, built to serve in the Dutch East Indies and Dutch territorial waters in Europe. The class was originally planned to consist of 12 ships, but because of the German occupation of the Netherlands in the Second World War, three of the four ships that were still under construction were never completed.

The Jan van Amstel-class ships were 55.8 metres (183 ft 1 in) long, with a beam of 7.8 metres (25 ft 7 in) and a draught of 2.2 metres (7 ft 3 in) at deep load. They displaced was 450 long tons (460 t) at normal load, which increased to 585 long tons (594 t) at deep load. A pair of Yarrow boilers fed steam to two triple-expansion steam engines that each drove a single propeller shaft. The engines were rated at 1,690 indicated horsepower (1,260 kW) which gave the ships a speed of 15 knots (28 km/h; 17 mph). They carried up to 110 long tons (110 t) of fuel oil and had a complement of 45 officers and ratings.[1]
The ships could also be used as minelayers. The construction of the ships took place in two different shipyards, four by Gusto, Schiedam and five by P. Smit, Rotterdam.
