you should read life of pi by yann martel. Its an incredible book that won many awards. Its about the son of a zoologist who gets stuck on a lifeboat after the ship, carrying all the animals that they were transferring to a new zoo, sinks. The kid gets stuck on the raft with a orangutan, hyena and bengal tiger. Its all about how or if he survives on the lifeboat. Its extremely detailed in the ways of survival if lost at sea, and its seems right up your alley. its a beautiful story
