The Amsterdam ship Edam, also known as the Zwarte Bul, is still something of a mystery. The Wrangell Collection document gives the length as 124ft, while the traditional dimensions had a length of 120ft. Ron van Maanen has various sources quoted that give a variety of dimensions, as well as those of the Wrangell Collection document:
Wrangell Collection document: 124ft x 28ft x 11ft 6-1/2ft
"traditional dimensions": 120ft x 28ft x 11ft 6-1/4ft
5 April 1653: 124ft x 28ft
7 July 1653: 124ft x 28ft
7 July 1654: 120ft x 28ft
31 March 1665: 123ft x 30ft
14 April 1665: 124ft x 29ft
There is also some variation in the armament:
Wrangell Collection document: 6-brass 12pdr, 14-8pdr, 4-brass 6pdr, 4-6pdr
16 November 1652: 6-12pdr, 12-8pdr, 12-6pdr
4 April 1653: 6-12pdr, 14-8pdr, 8-6pdr
7 July 1653: 6-12pdr, 14-8pdr, 10-6pdr
April 1655: 6-12pdr, 14-8pdr, 8-6pdr, 2-6pdr (?) drakes
14 April 1665: 18-12pdr, 16-6pdr, 4-3pdr
