Will it float? Is it "waterproof?" In other words, how good is the quality of the surfaces that I've created?

Close all three of the openings.

Create a sweep at x=-1

Trim this

Join all. Go to the Mechanical Design - Part Design workbench. Close surface

Hide the surfaces

That is a solid.

It floats.
