Ship of the line

A ship of the line was a wooden, three-masted sailing warship built to fight in line-of-battle formations and trade broadside fire with enemy capital ships. The type formed the backbone of major navies from the mid-17th through the mid-19th century, with HMS Victory standing as a famous 104-gun first-rate example.
