STD RPM
FULL 100 RPM
FLK I 125 RPM
FLK II 150 RPM
FLK III >150 RPM

5. Bells GT - Controlled by pitch and speed of the propellar
Diesel - controlled by speed
Steam - controlled by the speed + 12 kts

6. Controllable Forces Propellers -
single - turn clockwise
double-
STBD - clockwise
PORT - counter clockwise
Side Force - due to the rotation of the screw
none on a twin screw
will force in the direction of rotation. It is as if the screw is walking on the bottom

7. Controllable Forces
Rudder - Usually behind the prop to maximize the thrust

8. Uncontrollable Forces
Bernoulli’s
UNREP
suction
Bow and stern cushions
Shallow Water Effects
Pounding
Loss of rudder effectiveness
Sink due to bernoulli’s
Squat

9. Uncontrollable Forces
Wind - bigger problem on a carrier
Current
Helmsman

10. Definitions
Pivot Point - The point on the centerline about which the ship turns
forward
small - last frame of the bridge
big - forward of the bridge
Astern
stern of the ship

11. Definitions
Turning circle - line scribed by the pivot point in 360 degree turn
Rudder
Speed - real slow and fast increase the diameter
Advance - the distance gained toward the original course
Transfer - the distance gained in the direction of the turn

12. Definitions
Tactical Diameter - the amount of transfer made in 180 turn
Standard - std rudder and bell
Reduced - any speed and full rudder
Kick - swinging of the stern
Surge - the amount of forward motion while slowing to a slower speed.
