Duyfken has been designed as an authentic replica. Installation of modern machinery and extra ballasting to comply with current survey requirements were undertaken after initial sailing trials. Duyfken performs well under sail. She easily makes 4 knots in moderate conditions and frequently reaches 7 knots.

Although the rudder is small and the tiller turns the rudder through a limited arc, the ship maneouvers well and tacks easily. Sails are flax and rigging, including the standing rigging, is hemp rope.
