Designing Duke of Kent without Santisima Trinidad's instability

How would HMS Duke of Kent avoid the problems that plagued Santisima Trinidad?

By being designed from the start as a larger four-decker rather than repeatedly enlarged from an earlier hull.

Santisima Trinidad underwent repeated changes to her decks and armament, prompting a comparison with the much-altered Furious. Duke of Kent would instead be designed from the outset as a 170-gun four-decker. The expected greater length and hull depth are recalled with some uncertainty. Improvements in naval architecture also inform the expectation that she would be stable. She would still be difficult to steer and handle, so stability would not make her an easy ship to sail.
