In Seafight the player controls ships in action oriented sea fights. He has
a choice between England, France, Spain or pirates and can play 15 missions on
every side. There are four possible goals: sinking ships, neutralizing
fortresses, conquering ports or defending ships.

In principle these tasks are easy to accomplish – turning and firing aimed
broadsides is that is needed. But in later levels the player has to control
multiple ships and has to play attention to their course. There are also
several obstacles on the map like rocks or maelstroms which can wreck a ship.
The game is played with a combined mouse-keyboard control system. There is no
installation on hard disc needed.
