Any convex shape will tend to minimize the forces due to buoyancy and "horizontal" should always go less deep (or equal for a sphere) than "vertical"

- WJW 6y agoCool, I stand corrected. I tried with a few triangles of my own but they never stayed upright, but maybe I just suck at drawing and they all started too far off-center to remain in the little "valley" of the stability diagram.
