The Garmin GPS 72 is accurate to within 3 meters, has a relatively large screen and floats. The GPS 72 is preloaded with worldwide cities and is also mariner-friendly, not just because it floats, but also because it's packed full of marine navigation aids like day beacons and buoys. It also has celestial data like tides, sunrise/sunset and a hunting and fishing calendar.
