Use grapeshot, aim for the hull

From Create Your Own Story

Your hail of grapeshot barely manages to chip the other ship's paint. Guess it takes something a little bit heavier than pellets to seriously damage a hull... But you do not have long to regret your mistake. The Portuguese galleon completes her maneuver and opens fire with her entire broadside, utterly destroying Midnight (and you in the process).

THE END.
