In the Witsen Scheepsbouw program, this separate department has been incorporated to show how Dutch ships were built in the 17th century (and well beyond). To our 21-century eyes, it seems strange that construction was done without a pre-drawn design on paper. The construction sequence seems even more unusual: first the outer skin and only then the frames. How the shipbuilders achieved this is shown in a series of 14 construction phases, whereby the user is immediately interactively familiar with the names of the different parts, which can be shown or omitted at will.
