Ship number 164 in Vreugdenhil's list

I had wondered if the ship Omlandia, number 164 from Vreugdenhil's list of Dutch warships, might actually be the Stad Groningen en Ommelanden, but the dimensions are wrong. Vreugdenhil gives the dimensions as 125ft x 29ft x 11-1/2ft, the same as those for the Noorderkwartier ship Eenhoorn. He says that the ship was purchased in 1652 and was last mentioned in 1655. The ship is said to have carried from 40 to 44 guns. I have not seen a mention of any similar ship in documents from 1652 or 1653. I just consulted Dr. Elias's appendix III in the book De Vlootbouw in Nederland. He lists the Omlandia as having 30 guns and calls the ship old. He gives the length as 122ft. His source is a list of ships in the Nationaal Archief (the former Rijksarchief), from the Secrete Loketkas, no.993. That is likely to be an obsolete reference. It still should be possible to look in the Secrete Loketkas for 1655 and to find the list. There is also another list of ships of 100ft and longer, apparently from that period, but without a modern reference (he gives Rijksarchief, no.XLVIII, no.11).
