A twin-screw vessel is easier to maneuver than a single-screw vessel because the twin-screw vessel().
A、permits the rudder to move faster
B、generates more power
C、can turn without using her rudder
D、can suck the water away from the rudder

B、generates more power
C、can turn without using her rudder
D、can suck the water away from the rudder
A、Go ahead on both engines with the rudder hard to one side,if on a twin-screw vessel B、Back down with the rudder hard to one side,if on a single-screw vessel C、Take advantage of the tendency to back to port,if on a twin-screw vessel D、Turn so that the tendency to back into the wind can be used,if on a single-screw vessel
A、one engine and a steering oar B、both engines at the same speed C、one engine at a time D、one engine running at reduced speed and controlling the vessel with the other
A、one engine ahead and one engine astern,with full rudder B、one engine ahead and one engine astern,with rudders amidships C、both engines ahead,with full rudder D、both engines astern,with full rudder
A、If one screw is stopped,the ship will turn toward the side of the stopped screw B、The principal force which turns the ship is set up by the wake against the forward side of the rudder C、Turning response by use of the rudder only is greater than on a single-screw vessel D、With the rudder amidships,the ship will steer a fairly steady course
