So you're asking if the weight of the ship would increase/decrease as it sank? Presumably because of the immense pressure?

I have to assume that 1000# block of iron is going to weigh practically 1000# whether it's in orbit in the ISS, sitting in your driveway or at the bottom of the Mariana trench. Obviously, the weight of the water above the ship would be pushing down, but that water (much like air) is pushing on the ship from all directions. Gravity is still pulling on the metal that the ship is made of with roughly the same force.

A quick google has provided that the difference in gravity from sea level to the top of Everest is 0.25%, and even at 200,000km, it's still 94% of sea level.
