ABSTRACT:
Transport ships having a relatively large structure over the water line, such as a pure car carrier, container ship and a passenger ship tend to receive the air resistance during the sailing. When sailing aslant against the wind, check helm had to be effected so far to cancel the swinging moment causing an extra increase in the underwater resistance. A low-fuel-consumption transport ship described has a structure over the water line, including a bow of a shape integral with the bridge of a hollow nearly semispherical to quarter-spherical shape or a partly cylindrical shape which is smoothly continuing to the stern to decrease the air resistance. The low-fuel-consumption transport ship further has a vertical tail incorporating a chimney and is rotatable on the uppermost stern deck to cancel the swinging moment in the air, without almost requiring check helm and, therefore, decreasing the underwater resistance.
