Applying my theory about Rotterdam ships

Early this morning, I applied my theory about lasts and Rotterdam ships to the data that I had entered into my ship list the latter part of this week. The idea is that the last figures (gross tonnage) for Rotterdam ships is calculated from Maas feet. If you calculate from Amsterdam feet measurements, the figures are about 30 percent greater. Doing this has interesting results. For Example, the ship Hond, built about 1604, has the same dimensions as the ships Overijssel and Utrecht that found in the First Anglo-Dutch War (100ft x 23ft x 8ft in Maas feet).
