    A boat in zero gravity : would it sink?

    If a boat was floating on the sea out in space, would it sink?

    Assuming you enclose the boat and sea (of water?) in a box and assume normal pressures and temperature, yes, the boat would sink. In all directions.

      How would you notice?
      The Mods stole my post count!

        What would hold all the water molecules together?

          Yes it would, the boat and the water will attract each other assuming no other forces are present.
          Science isn't about why, it's about why not. You ask: why is so much of our science dangerous? I say: why not marry safe science if you love it so much. In fact, why not invent a special safety door that won't hit you in the butt on the way out, because you are fired. - Cave Johnson

            What holds them together without gravity?

            Surface tension.

            Hth.

              I don't think it would work, but anyway, the temperature in space is so low that the water would be frozen. The ship would sit on top of a lump of ice.

                On top?

                  well, not on top, but on it.

                    You're assuming that heat is only conducted, transferred via convection.

                    Radiation, convection and conduction are all methods of heat transfer.

                    I think the water would boil away if not contained by some form of pressure vessel.
