The Mary Rose Sinking

If she'd been shipping water for several hours, the Mary Rose could easily have had about a hundred tons of water in the hold. That would have been quite sufficient to significantly upset her balance. A hundred tons ofWater would equate to about 18 inches water depth in the bottom of the ship. So it wouldn't look like very much. It would look even less when you consider that the ballast in the Mary Rose was beach shingle,. When you mix it with water, the water disappears, but the beach shingle becomes itself fairly fluid. And so as it moves, it could move over to one side quite rapidly and actually produce that final moment of movement which dragged the ship sufficiently low
