<p>A stem structure for reducing wave resistance is disclosed. In the stem structure for reducing wave resistance, the performance in second and third sailing areas is enhanced while the performance in the design point of a bulbous stem (stem bulb) is maintained by installing a duct-type unit (100, 200, 300, 400) in the bulbous stem formed in the lower part of the inclination part of a stem part (2) to reduce wave resistance and variously changing the shape of the duct-type unit (100, 200, 300, 400). Thus, the present invention can provide the performance evenly satisfying the management patter of a ship owner and can readjust the performance appropriate to a new sailing pattern by mounting a duct in case of an existing ship.</p> |
