One gunpowder barrel no matter where it hits the sloop (even if you run into it) will render it completely disabled with 10 points of damage 100% of the time. 4 max size holes, broken sail (3x repair + raise), and max damaged steering wheel (3x repair).
The Brig can suffer close to the same fate but the barrel needs to be set off at the midway point of the ship to blow up either 2 sails + anchor or sail + wheel. Though, the Brig can still either sail making it hard to board or it can turn so the enemy cant land shots from a blind spot.
The gallon can shrug off a gunpowder barrel explosion no matter where it gets hit it can keep moving (still causing a ton of damage but it's manageable).
The gunpowder barrel no matter what will cause 4 max size holes and completely destroy any sails, anchors, or steering wheels in range. For such a easy to find common item that is way too much damage.
