    Surface tension.

    Hth.
    They have mass therefore they create their own gravity.

      To sink, you need a force pushing the boat down through the water.

      Force = Mass x Acceleration.

      No Gravity = No acceleration, therefore no force, so it cannot sink. HTH.

        Second law of thermodynamics: the entropy of a system always increases. The boat would sink, but in no particular direction. That is, the system would tend to randomness, the boat being buffeted by water molecules from all sides: sunk.

              I just made up this thread for fun and look at you guys!

                If the sea were in a void in the middle of a planet then it would be weightless but could still have an atmosphere to stop it boiling or freezing. The boat would be attracted to the centre by the sea's own weak gravity, but being a boat, would be less dense than water so would not sink.

                  A ship will float when the weight of the water it displaces is less than or equal to the weight of the ship.
