Lets assume your object sinks - the density of the object is greater than the density of water.

When the object is on the ship, the amount of water displaced will be dependent on the weight of the object.
When the object is under the water, the amount of water displaced will be dependent on the volume of the object.
Since the density of the object is greater than water, the volume of water displaced under the water is less than the volume of water displaced whilst above water

Therefore the water level will rise a teeny tiny amount.
However the water level will fall relative to the side of the ship because the ship will not displace quite so much

...would trade a certain amount of safety for freedom.

We want a level of policing that provides a reasonable level of security but does not compromise our lifestyle unless a large number of casualties would result. One or two events per year do not necessitate loss of liberties that affect everyone.

Dirt isn't a big problem, nor are the other materials.

The premise has been examined by Andy Weir in his fiction book "The Martian", which shows that you can survive on relatively little. I am making the assumption that he did his chemistry and biology homework whilst writing this :-)

Elon Musk is Jewish, so he's probably going to want to send a bunch of Jews there to set up settlements before anyone has time to object.

Well, having Mars as New Israel would be one way of fixing the Middle East wars....

It would be easier to move the Palestinians there though, as there's less of them.

The unfacts, did we have them, are too imprecisely few to warrant our certitude.
