The crew are all in frozen sleep. One man is woken early, stays awake, eats a lot of the provisions and paints a giant mural (about the adventures of a prince) on the corridor walls, he eventually dies when very old.
The ship arrives at its destination, the crew is woken up and discovers the mural and lack of provisions.
Another ship with a faster engine has been sent from earth and catches up with the original ship just as it lands on the new planet. The new ship crew are antagonistic, a new order has been established on Earth. One of the first ship crew escapes, canoeing down a river to explore the new planet.
I think there is a sequel.
