Ship Having Member To Reduce Added Resistance Due To Waves

摘要

Disclosed is a ship including a device for reducing an added resistance due to waves. The ship including a buoyancy device according to an embodiment of the present invention includes a buoyancy device mounted on a stern of a ship and mounted in a draft upper portion adjacent to a draft line, wherein the buoyancy device generates buoyancy when the stern of the ship is lowered down so as to reduce pitch movement of the ship. According to the ship of the present invention, the buoyancy device of a specific structure is provided such that pitch motion of the ship can be remarkably reduced. As a result, an additional added resistance attributed by movement of the ship in operation with waves can be remarkably reduced.
