Teemu koivumäki has the best picture I have seen of the Sovereign of the Seas (1637).
If you are not familiar with his site, Sailing Warships: List of Sailing Warships from 17th. to 19th. Century, you need to be. There is no other source available, in print or on the Web, that has as much information in one place. He has had many contributors, including myself.
I contributed to the Dutch ship section, especially that for the Directors' ships during the First Anglo-Dutch War. Professor Jan Glete pointed out that there was information in the Nationaal Archief, in the Hague, for about 40 Directors' ships. Rick van Velden was able to find much of what Prof. Glete had seen about 20 years ago, as well as a few documents that Prof. Glete had not seen.
