Oars

Sailing vessels and ironclads may make limited use of oars, while oars primarily propel galleys. Longboats and sharkboats are primarily oar driven vessels. Oars may push a vessel backward, stop or push forward in one of three speeds (cruising speed, battle speed and ramming speed).

Stamina

Rowers must expend extra energy to row at Battle Speed and Ramming Speed. Most crews begin the game with 10 points of Stamina.

The easiest way to keep track of Stamina is to start the game with 10 chits, stones or pennies. As these are expended remove them from sight. This way you can very easily and visually keep track of Stamina without taking notes.
