script: Paviljoen cabin),
Sekreet (toilet), Kamer (room), de Groote kamer (great cabin), Bottelerij (steward’s pantry), Combuys (galley) and Kabelruym (cable tier). T e use of the term Cappitijnskamer is notable. In the seventeenth century ‘captain’ was an army rank and was only used on men-of-war. On all other ships, the commander was called ‘skipper’. In Holland the title ‘captain’ for the captain of a ship generally comes into vogue much later. Witsen therefore calls the compartment in question in the notes on his plate Schipperskamer.
T ere is another example of a term that is probably incorrectly used. At
the level of
waterstrook is written, a word that does not appear in any of the available contemporary sources about shipbuilding. T ese mention scheerstrook and, in rare cases, waterlijn, but the combination waterstrook is at the least suspect.
T ere are construction lines in the drawing, suggesting that this is not a preliminary design drawing, but rather the representation of an already
the waterline
When looking at it from a technical point of view there are some remarkable things. T e construction lines are dashed lines that connect two extreme points of a curved part, such as the bow in top view, the stem post or a frame. T ey are divided into four equal parts, on which perpendicular lines are erected up to where they hit the curved line. T e length of those perpendicular lines defi ned the bend, a simple and eff ective way to capture the shape of an existing ship. T e curvature of the stem post also is depicted with a diagonal divided into four equal parts. It is understandable that for the measurement the lower point the lip of the stern on the keel was chosen, but it is hard to grasp why the 7-3/4-foot rake was also calculated from that point, because in Dutch shipbuilding the rake of the stempost was always measured from the upper front of the keel.
If for a moment we forget the technical irregularities in Storck’s drawing, such as the mentioned absence of the fore frames, the erroneously depicted rake, the unusual terminology, such as waterstrook and Cappitijnskamer,
