Is there any instance in which a buoy weighs more than the displaced water and still floats? I'm willing to consider different shapes/materials/ or depths.

What if I added helium to the buoy, or that sort of thing? The only thing that's important is that it floats and weighs more than water.

I'm fairly certain that an object must weigh *less* than the displaced water in order to float.
If I'm right, the answer is no, it won't float.

If an object displaces more water than it weighs, it will float regardless of shape or material. Depth is a factor since density and, therefore, displacement increases with depth.
