Captain Natick does not want to take a kitten on board his ship as it sets sail, but his daughter convinces him that the scrawny yellow cat will bring him good luck. Onto the ship the kitten goes, and so begins the adventurous, cliff-hanging, lucky life of Jacob Tibbs, who must learn how to hunt rats, brave a mutiny, survive on a desert island, and, most importantly, navigate the tricky waters of shipboard life, no matter where the waves may take him.
