A ship according to one embodiment of the present invention comprises: a hull; a cabin arranged on a deck of the hull; and a bridge wing extended left and right up to a predetermined distance from the upper side of the cabin. The bridge wing includes: a frame in which at least one portion of the bottom surface is formed in a penetrated shape and made of a metallic material; a grating member arranged to cover the penetrated bottom surface of the frame, made of FRP and having a grid shape opened up and down; and a hand rail arranged on the periphery of the frame and made of a plurality of horizontal members and vertical members. The grating member is restricted such that a value resulted from the operation of dividing the thickness (T) of the grating member by the width (L) of a grid opening conforms to mathematical equation which is represented by T/L <= V * R_H and T/L >= V * R_L, wherein V is 0.25 as a vision variable considering a vision of a person standing on the bridge wing, R is an extension distance variable considering a gap (l_h) between the horizontal members and a gap (l_v) between the vertical members of the hand rail and calculated as equation which is represented by R_H = [A_H + { (l_h * l_v) * B}] and R_L = [A_L + { (l_h * l_v) * B}], wherein A_H is 24 as an upper limit constant, A_L is 1 as a lower limit constant, and B is 0.6 as a transformation constant. According to the present invention, the ship can be easily manufactured.

    본 발명의 일 실시예에 따른 선박은, 선체; 상기 선체의 갑판 상에 마련되는 선실; 상기 선실의 상측에서 좌우로 일정 거리만큼 연장되는 브릿지윙을 포함하며, 상기 브릿지윙은, 저면의 적어도 일부가 관통된 형태이며 금속 재질로 이루어지는 프레임; 상기 프레임의 관통된 저면을 커버하도록 마련되며, FRP로 이루어지고 상하로 개방된 격자 형태를 갖는 그레이팅 부재; 및 상기 프레임의 둘레에 마련되며 다수의 수평부재와 수직부재로 이루어지는 핸드레일을 포함하며, 상기 그레이팅 부재는, 상기 그레이팅 부재의 두께(T)를 상기 격자 구멍의 폭(L)으로 나눈 값이, 다음의 수학식을 따르도록 한정되는 것을 특징으로 하는 선박. T/L ≤ V * RH T/L ≥ V * RL 여기서, V는 브릿지윙에 서있는 사람의 시야를 고려한 시야변수로 0.25, R은 핸드레일의 수평부재 간의 간격(lh) 및 수직부재 간의 간격(lv)을 고려한 연장거리변수로 다음과 같다. RH = [ AH + { (lh*lv) * B } ], RL = [ AL + { (lh*lv) * B } ] 여기서, AH는 상한상수로 24, AL은 하한상수로 1 이며, B는 변환상수로 0.6 이다.
