A French intelligence report from the early 1670's, found by Prof. Jan Glete, and shared with me, gives some dimensions for the Wapen van Holland. The information is actually from Jan Glete's notes, taken from a document. The length is given as 131ft and the beam is given as 32ft.
The text is my translation of what is in Mollema's "Honor Roll".
The ship information is from my unpublished list, Dutch Ships 1620-1700.
