200 last ships

I recently received some information from Ron van Maanen about Zeeland ships. Some of the older ships were larger than most of the ships in service in 1652. For example, the Middelburg, built in 1632, and the Vlissingen, also built in 1632 were both 200 lasts. A 200 last ship might be 125ft x 29ft x 11-1/2ft, in Amsterdam feet.
