The original plan for the 30 ships

The original plan for building 30 ships in 1652-1653 would have been much better than what was actually built. Inter-province politics eventually resulted in a much weaker building program. The original plan would have included:

Charters:  
150ft x 38ft x 15ft x 8ft 
140ft x 36ft x 14-1/2ft x 7-1/2ft
134ft x 34ft x 14ft x 7ft

   Charters:   150ft    140ft    134ft
Admiralty:

Rotterdam       1 ship   2 ships  2 ships

Amsterdam       2 ships  4 ships  4 ships

Zeeland         1 ship   2 ships  2 ships

Noorderkwartier 1 ship   2 ships  2 ships

Friesland       1 ship   2 ships  2 ships

Totals:         6 ships  12 ships 12 ships

This would have given the Dutch the equivalent of 6 English 2nd Rates, 12 English 3rd Rates, and 12 English 4th Rates. Eventually, they only built on 150ft ship among the first 30 ships.
