Evasion and Pursuit
On the wide, open sea, one ship can spot another from miles away, making it virtually impossible to surprise another ship. If both ships want to engage in combat, the ships close with one another and begin ship-to-ship combat normally. If one ship wants to avoid combat, however, a chase ensues. At the GM’s discretion, a faster ship can always catch a slower ship, but even slow ships can take advantage of favorable winds, currents, or coastal terrain to make good their escape.
When two ships first encounter one another, the pilots of the two ships must make three opposed sailing checks. Whichever pilot wins at least two out of three of the opposed checks is victorious. If the pursuing ship wins, it catches up to the fleeing ship and ship-to-ship combat begins. If the fleeing ship wins, it escapes. If the result is a tie, the pilots should begin a new series of three opposed checks.
Such chases can take days, as one ship struggles to outmaneuver the other. At the GM’s discretion, roll 1d4 to determine the number of days a chase lasts.
Withdrawing: Once in ship-to-ship combat, a ship can withdraw from combat by simply moving off the edge of the battle mat, ending ship-to-ship combat immediately. At the GM’s discretion, the ship has either escaped completely, or the two ships can go back to the evasion and pursuit rules above.
