Minecraft wiki entry for Shelters, associated text: If you find yourself using boats in a general area often, making a dock or two is a good idea. They can help prevent your boats from drifting off into the ocean, or slamming into a wall when you exit, thus breaking the boat. Dispensers can also be placed here and filled with boats for convenience. Chests filled with boats are a good idea too. There are several ways to make useful docks.
