I frequently get confused with what Ron van Maanen has

Ron van Maanen usually does not mention captains. Generally, all he has are listing for ships by name and admiralty (possibly Directors). I often see instances where, given that I cannot tell what the captain is meant to be, that he seems to have combined two or more ships into one entry. I would have said, from one notation in his Eenhoorn entry in the largest list, that he had seen the list that I just received of Noorderkwartier ships. He has the dimensions for the ship of 1625 (125ft length) that are in this list, and which I have seen no where else. He mentions a date, 20 February 1654, which seems plausible for this list. However, reducing my confidence in what he has, he includes the dimensions and completion date for the ship called Hoorn in this list I have (a 120ft ship).
