Naval Tradition is a social policy in Civilization V. It is part of the Exploration tree. A society can develop different kinds of traditions, including a tradition related to seafaring. Thus the figure of the old sailor, with pipe in mouth, long white beard and tally cap, telling stories in the corner of the local pub, becomes a mythical figure which agitates the fantasy of young people, making them see adventures in far-off lands, contacts with exotic people and cultures...and, of course, riches to be earned. Thus, each maritime building in a city evokes these naval traditions and increases happiness in the city.
