u/Bitter_Counter_2556

I'm currently in college and I'm doing a presentation on maritime engineering as a field. As part of it, I need to pick a major failure of the field to highlight and discuss. Ideally, the failure should be some critical flaw as a result of the way the ship was designed or constructed. However, I'm absolutely not going to do the titanic under any circumstances because it's just way too cliched. Anyone have suggestions? Can be recent, can be older but preferably something from the 20th century or from the early age of coal powered ships.
