The Work Boat is a Civilian unit available from the Ancient Era.
The sea can provide much to a civilization. This can range from protein in the form of seafood to energy - from whale or from oil. For all of human history, courageous men and women have been going to sea in boats to harvest the sea's bounty. Doubtless they will continue to do so until the end of time, "when the sea shall give up her dead."
The Work Boat is a naval unit, which means that it can only be constructed in coastal cities. It can be used to improve water resources such as Fish, Whales, Pearls, and Oil. The Work Boat is consumed when it constructs the improvement, so improving multiple water resources will require multiple Work Boats.
Work Boats can't enter ocean hexes until Astronomy is discovered. Work Boats cannot engage in combat and are immediately destroyed if an enemy enters their tile, so defend them if there's danger nearby.
