[0002] This application claims priority from Korean Patent Application No. 10-2012-0074011 filed on Jul. 6, 2012, the contents of which are hereby incorporated by reference in its entirety. technical field

[0003] Various embodiments relate to ships. Background technique

[0004] Ships are capable of transporting ore, large cargo such as containers or gas. Since the ship sails floating on the water, it will be affected by the wave-making resistance generated by the waves as the ship advances. Therefore, customarily, in order to reduce the wave-making resistance, the ship has a spherical bulbous bow protruding from the bow.

[0005] However, the upper part of the bulb may be grooved and as such there will be unnecessary drag affecting the vessel when the vessel is in a tilted position or pitched fore and aft while the vessel is in a trim motion. The bulbous bow may actually increase the ship's resistance in the event of dr...
