SHIP ENCOUNTERING LESS FRICTIONAL RESISTANCE

摘要

Provided is a ship encountering less frictional resistance. The ship blows air into the water to reduce the frictional resistance between the hull of the ship and the water and prevents bubbles from being entrained in a propeller (16) of the ship while the strength of the hull is maintained. An air blowing device (30) blows air into the water through air blow ports (31-33) formed in a ship bottom (13). An air collection device (40) collects air in the hull through first to third air collection ports (41-43). The propeller (16) is disposed on the centerline (CL) of the ship. The first air collection port (41) is formed across the centerline (CL). The second air collection port (42) is formed on the port side of the centerline (CL) so that the second air collection port (42) protrudes further to the port side than the first air collection port (41). The third air collection port (43) is formed on the starboard side of the centerline (CL) so that the third air collection port (43) protrudes further to the starboard side than the first air collection port (41). The second and third air collection ports (42-43) are closer to the bow side of the ship than the first air collection port (41). Each of the first to third air collection ports (41-43) comprises a plurality of air collection holes (41a-43a).
