Dutch measurement: Length from stem to sternpost: 180ft Beam inside the planking: 52ft Hold: 17ft English measurement: Length on the keel: 135ft Beam outside the planking: 46ft Depth of hold: 15ft I would estimate the length on the gundeck to be about 175ft in English feet. Herbert Tomesen, at Artitec, is using a much smaller set of dimensions: Length from stem to sternpost: 170ft Beam inside the planking: 38ft Hold: 18ft This would translate into English measurement: Length on the keel: 127ft-10in Beam outside the planking: 33ft-8in Depth of hold: 15ft-11in estimate length on the gun deck: 166ft This actually seems more reasonable than Ron's dimensions. Ron is pretty consistent, though, with his large retourschip dimensions. I have yet to find the source, however.
