According to the present invention, a bulbous bow of a ship, which maximizes bow resistance reduction, allows an upper side surface of a bulbous bow formed on a lower portion of a bow of a ship to be positioned on an upper portion of a design draft line so that the upper side surface of the bulbous bow is exposed above a water surface when navigation of the ship is stopped, thereby maximizing offsetting of a tidal wave generated when advancing, reducing shape resistance generated by a shape of the ship in a low speed or a ballast state in which a tidal wave offsetting principle is weakened as volume in a height direction is secured and the full width is reduced, and improving flow generated on a front surface of a bow part so as to contribute to mileage of the ship and economic navigation.

    본 발명에 따른 선박의 구상선수는 선박의 선수 하부에 형성되는 구상선수의 상측면이 설계흘수선 상부에 위치되어, 선박의 운항정지 시 구상선수의 상측면이 수면 위로 드러나도록 하여, 전진 시 발생하는 조파의 상쇄를 극대화할 뿐만 아니라, 높이방향 체적확보 및 전폭을 줄임에 따라 조파상쇄의 원리가 약해지는 저속 또는 밸러스트 상태에서 선박의 형상으로 인해 발생하는 형상저항 감소 및 선수부 전면에서 발생하는 유동의 흐름이 개선되어, 선박의 연비 및 경제적 운항에 기여하는 선수 저항감소를 극대화한 선박의 구상선수를 제공한다.
