The size of the Rotterdam ship Brederode
The two large flagships provided by the Admiralty of the Maze (or Rotterdam) for use by the fleet commander were both said to be 300 lasts in size. Those were Rotterdam lasts, and not comparable to ships from other admiralties. To compare, you have to multiply by 1.3 and then round to the nearest ten lasts. The problem is that the 300 number is an estimate or nominal number, not a real figure. The Brederode is often said to have dimensions of 132ft x 32ft x 13-1/2ft. Those are Maas feet, however, not Amsterdam feet. The calculated size in Rotterdam lasts is about 275 lasts, not 300. You have to very liberally round to get the 300 last figure. My estimate of a real size for the Brederode, in Amsterdam lasts, is 360 lasts.
