The counter argument about the Kalmar Sleutel

The counter argument that says that the Kalmar Sleutel dimensions are in Maas feet is based on two facts. One is that all Rotterdam ship dimensions from 1652 through 1654, prior to the new construction, were stated in Maas feet. The length of the Kalmar Sleutel, as stated, is quite short at 103ft. If we assume that these feet were Maas feet, the converted dimensions are more plausible: 112ft-4in x 27ft-3in x 12ft, with a height between decks of 6ft-6in. The dimensions in Ron van Maanen's document and in David de Wildt's list were: 103ft x 25ft x 11ft, with a height between decks of 6ft. Sources:
