Does having a keel imply that the ship is self-righting? Like, completely submerged, does it also guarantee that the ship floats back to the top, oriented?
But also no, if it’s capsized, the boat may right itself in time before it floods to a point where it sinks.
A fully submerged boat will not bob to the surface. The keel adds stability and (counter)weight, but negative buoyancy - what keeps the boat afloat is the air in the hull.
Once it’s fully submerged, there’s nothing pulling it up (unless you have some seriously good (and closed!) hatches…
