Wattamp Ocean
East of Fereina and west of Hohm was the Wattamp Ocean. The Wattamp was treacherous to sail because of many sandbars and shallow areas--expert navigators were needed to sail the Wattamp without accumulating severe damage to a ship's hull or accidentally running aground.
The Wattamp had several large stretches of extremely shallow water. These shallow water areas could be as shallow as 3 feet, and could cover areas of up to 2 square kilometers.
