At interstellar speeds (1-20%c), the front of your ship will have massive shielding against radiation and matter, the back will have massive shielding from the engines with a very long and thin bit in between to live in and large surface area constructions on the side to radiate away heat. Accurate sensor info about whats in front of you becomes a bit tricky due to a bunch of effects from your speed, like for instance the need to sit right next to a bunch of super hot radiators, redshift, increased noise, and hitting something bigger than a ton orso will likely be the end of your ship, no matter how big it is so it's gonna be a thing for gamblers or the religious.
