The Man-o-War is Europe's most powerful ship. Their design is a closely guarded secret, meaning no colony will ever be able to build one. The best defense against this ship is the Ship of the Line, a ship of comparable naval might.
The Man-o-War was the most powerful ship of its era. First created under the reign of the English king Henry VIII in the 16th century, these massive weapons of war quickly became the most feared vessels in the seas. The Great Harry and the Mary Rose were two of the first Man-o-War's, each capable of carrying over four hundred crewmen and over one hundred cannon. Strangely enough, both the Great Harry and the Mary Rose met rather inglorious ends - the Great Harry is thought to have burnt while docked and the Mary Rose was sunk by an inferior French vessel.
