This is a game for the piecepack game system. The rules and examples of play are in the files section. In the Age of Sail there was the development of the Battle Line to have a combat effectiveness as high as possible. In particular the British Royal Navy laid this doctrine down in the Fighting Instructions and adhered to them in a stubborn manner. This led in the second half of the 18th century to many undecided battles which could have been won with a little initiative. The Navy had to wait for an Admiral Nelson to change this. In Piecepack Seabattle each player tries to destroy the opposing battle line with his own battle line. During manoeuvring you can achieve an advantageous position. During the fighting you need luck as it was in all sea battles.
