These rules are designed to give a fast, rather stylised game reflecting warfare between galleys in the Mediterranean in the 16th century. They could easily be adapted to cover naval operations in the Baltic in the 16th and 17th centuries. They do not cover galleasses and galleons for two reasons; one, sailing rules introduce unwanted complications and two, working out broadside firing is rather difficult.
