PROBLEM TO BE SOLVED : To enable agriculture for ensuring stable yield of agricultural crops irrespective of the problem wherein an agricultural site is real estate and thus yield of agricultural crops varies depending on weather, and to enable fishing industry for catching abundant fishery products migrating and living in the sea, as a ship and a vessel having a large area equivalent to an agricultural site cannot be manufactured with the weight of the conventional known materials used for manufacturing the ship and the vessel.SOLUTION : This ship 1 having a large area and large volume is manufactured by using a styrene foam as an independent cellular body and serves for agriculture and other industries at the same time. By mounting an actually operating GPS device on the ship to communicate with a meteorological satellite, the ship can navigate stably to any place on the earth on the sea while recognizing weather conditions accurately, thus ensuring yield of agricultural crops stably.COPYRIGHT : (C)2010, JPO&INPIT
