A twin screw vessel, making headway with both engines turning ahead, will turn more readily to starboard if you ______.
A.reverse port engine, apply right rudder
B.reverse port engine, rudder amidships
C.reverse starboard engine, apply right rudder
D.reverse starboard engine, rudder amidships
第1题:
A vessel is equipped with twin propellers,both turning outboard with the engines half ahead.If there is no wind or current and the rudders are amidships,what will happen?
A.The bow will swing to starboard
B.The bow will swing to port
C.The vessel will steer a zigzag course
D.The vessel will steer a fairly straight course
第2题:
A twin-screw ship going ahead on the starboard screw only tends to move ______.
A.in a straight line
B.to port
C.from side to side
D.to starboard
第3题:
---Slow ahead both engines! ---Slow ahead both engines! ()!
第4题:
Headway
Sternway
No way on,with engines stopped
No way on,with engines full ahead
第5题:
permits the rudder to move faster
generates more power
can turn without using her rudder
can suck the water away from the rudder
第6题:
discharge current
suction current
sidewise force
thrust
第7题:
turning maneuver
course setting
position fixing
regulating speed
第8题:
correct trim will be obtained more easily
drag effect will be cancelled out
side forces will be eliminated
speed will be increased
第9题:
one engine and a steering oar
both engines at the same speed
one engine at a time
one engine running at reduced speed and controlling the vessel with the other
第10题:
If one screw is stopped,the ship will turn toward the side of the stopped screw
The principal force which turns the ship is set up by the wake against the forward side of the rudder
Turning response by use of the rudder only is greater than on a single-screw vessel
With the rudder amidships,the ship will steer a fairly steady course
第11题:
Go ahead on both engines with the rudder hard to one side,if on a twin-screw vessel
Back down with the rudder hard to one side,if on a single-screw vessel
Take advantage of the tendency to back to port,if on a twin-screw vessel
Turn so that the tendency to back into the wind can be used,if on a single-screw vessel
第12题:
one engine ahead and one engine astern,with full rudder
one engine ahead and one engine astern,with rudders amidships
both engines ahead,with full rudder
both engines astern,with full rudder
第13题:
When turning a ship in restricted space with a strong wind,it is normally best to ______.
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
第14题:
In a twin screw ship going half-ahead,both screws turning outboard and the rudder amidships no current or wind, the vessel will ______.
A.Move bodily to port
B.Move bodily to starboard
C.Move in a zig-zag motion
D.Steer a fairly straight course
第15题:
When dead in the water,it is often difficult to find the neutral position and slight headway or sternway may result
When going directly from full ahead to full astern,there is complete steering control
When the vessel has headway and the propeller is in neutral,there is no effect on rudder control
When maneuvering in port,full ahead or astern power can usually be obtained without changing shaft RPM
第16题:
in a straight line
to port
from side to side
to starboard
第17题:
reduce the fuel feeding of main engine of inner propeller
reduce the fuel feeding of main engine of outer propeller
firstly reduce the fuel of main engine of inner propeller, then reduce the fuel feeding of engine of outer propeller
reduce fuel feeding of two engines at the same time
第18题:
to starboard
outboard from the center
to port
inboard toward the center
第19题:
Move bodily to port
Move bodily to starboard
Move in a zig-zag motion
Steer a fairly straight course
第20题:
Both engines slow ahead
Engine slow ahead port
Engine slow ahead starboard
Engine both ahead
第21题:
reverse port engine,apply right rudder
reverse port engine,rudder amidships
reverse starboard engine,apply right rudder
reverse starboard engine,rudder amidships
第22题:
The bow will swing to starboard
The bow will swing to port
The vessel will steer a zigzag course
The vessel will steer a fairly straight course.
第23题:
forward spring line and going slow ahead on the inboard engine
after spring line and going slow astern on the outboard engine
forward spring line and going slow ahead on both engines
forward spring line and going slow ahead on the outboard engine
