In a book, written in 90's or earlier, a group of people is sent to a remote planet. This was possibly a punishment for a crime. They were sleeping in the space ship, and they wake up after landing. I don't remember what happened to the ship after that. I think the planet was quite primitive, possibly they were the first people there. They had laser guns.
One of the characters is called fat by others, because he is a big man and wears a loose shirt. Then he fights with someone and takes his shirt off, and the others see he is very athletic.
