Shipyards
The admiralty's yards were initially at Uilenburg, but around 1620 moved to Rapenburg and then around 1655 to the Eastern Islands (Oostelijke Eilanden), Kattenburg and Oostenburg. In time of war, over 1000 shipworkers and sailors worked at the admiralty yard.
The admiralty rope-works was established at Oostenburg and was approximately 300 meters in length. Because of the ropes laid alongside each other, sometimes at lengths of up to 220 meters, it was called a kuil or net. Old rope was also hung up, to provide oakum for closing up the seams between ships' boards.
