The ark isn't a "boat", its a floating man-made island. Having the opportunity to jump off into the water to run away might be interesting, but the majority of the maps aren't "waterfront". Most of them appear to be in various buildings of importance to the story. Even in the container city footage, the only time you are close to the water is at the security spawn.
Besides that, most weapons don't like to work properly underwater.
