I am curious what the thing looked like before they put in into the water. It is possible one side hit bottom during launch and that it is not floating, but rather one side sitting on the unlevel bottom.
This is what happened to the Costa Concordia. The ship floated just fine, but it was run hard aground on one side with devastating results.
According to NASA...,
a one-way trip to Mars would take about nine months. If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back home.
That's a long time to lock a group of people together in a can and expect everyone to get along.
How many people would have to go? A lot of bad things, mechanical and human, can happen on a nine month journey in a can with nothing available beyond what is onboard. Multi-skill tasking is only possible up to a point. Think you can teach a mechanic to perform surgery?
Their spacecraft needs to contain enough of everything - food, water, medicine, fuel, sanitary stuff, etc. - to sustain all those people for two years. It also must contain the return craft or possibly become the return craft if it's light enough to boost itself off Mars. We don't have or envision boosters big enough to launch that from earth; it would need to be assembled, tested, and verified in orbit, something we've never done at this scale, ISS notwithstanding. In addition to carrying or serving as housing, it needs to carry some kind of surface vehicle; the astronauts can't just walk around after landing.
The psychological problems of locking a group of people in a can (they'll have to live in one for at least three months while on Mars as well in transit) is, in my opinion, both untestable and unsolvable. They've got to cooperate closely to survive and bickering, jealousy, or hatred is going to affect that badly.
I could go on but that's enough for now. I'm sure you can all think of other problems that aren't going to be solved in a year or two of study.
I'm sure that someday we'll put humans on some of the rocky planets and moons but I'm not so naive as to believe I'll be around when it happens. For now, stick with robotic vehicles. They've served us very well in the past. They have better "senses" than humans, are cheaper and easier to get there, and we don't feel so bad when one of them dies.
