Was the mary Rose the ship that they kept adding stuff to the build and when it was launched it promptly rolled over as it was way out of balance?
Hi. There were a number of contributing factors -
1. The guns she sank with were not the ones she originally had at launch. As casting techniques of cannon improved heavier guns could be made in greater numbers and hence re-fitted to get the maximum firepower. Certainly heavier than the ones she was designed for.
2. The lower gunports are quite near the waterline. As she heeled over the ship took longer to recover to a vertical position and the water flooded in the open gun ports.
3. The design of the gun port lids indicates that in order for them to remain open a rope was tied to a higher point on the ship's exterior, maybe even to the inboard belaying rails. This being the case the gun crew could not close the ports themselves (like on, say, HMS Victory) even if they wanted to.
4. There is speculation that some of the crew were foreign and therefore may not have fully understood the orders being given when turning the ship.
Note that she did not sink when launched. Launched 1511, completed 1512, sank 1545, so she had quite a long life.
All sounds a bit like a disaster waiting to happen, doesn't it?!
Hope this helps.
