Naval Action - Rotterdam
This is a premium consumable ship. It is not refundable.

"Rotterdam" is a heavily armed West Indiaman built for the Rotterdam chamber of the Geoctrooieerde Westindische Compagnie. This is a strong ocean going vessel built to withstand storms of the Atlantic Ocean. Due to armament and size ships of this class were often mistaken for heavy frigates or light 4th rates and thus avoided. Beautifully decorated stern shows that it was built for a very rich trader group in the Compagnie.
