The De Drait Doerak 850 OK is a motor boat from De Drait. Founded in 1950 at Drachten in Friesland and still a family firm. It specialises in steel motor cruisers for the Dutch waterways, which it builds and charters itself. The hull measures about 8.5 metres. It sleeps up to 4.
Adriavela lists 4 boats of this model. They were built between 1969 and 1972, so the layout and the equipment differ from one hull to the next. The hulls here carry 1 cabins and 3 to 4 berths.
They all leave from Jachthaven Drachten de Drait. Under power the day is planned by distance rather than by wind, which suits short hops between bays and a crew that would rather swim than trim.
