摘　　要：介绍了为需要经常在浅海、内河等养殖区、浅水区水域上航行的用户所设计的一种小方形系数双桨双尾新船型．其船型特点是：双尾鳍向下延伸至基线，并带舵托，对螺旋桨和舵起到良好的保护作用；船底形状较为平坦，便于座滩．快速性试验结果表明，该船的阻力性能和推进性能在设计航速（Ｆｒ＝０．３８４）时都是优良的．This paper presents a new type of twin-screw-twin-stern ship with smaller block coefficient, which is suitable for running frequently on shallow waters and/or aquatic product breeding area. The distinguishing features of the hull form are as follows: (1) Each of the two skegs extends downward to the base line and afterward to the rudder pindle in order to protect the propeller and the rudder from being damaged; (2) The form of the hull bottom is designed considerably flat for the need of taking the ground. The model test results show that the resistance and propulsion performances of the hull form are satisfactory.
