1. GOLF
Guide ship. Used when ships are steaming in a formation there is 1 ship is designated as the guide.
2. ROMEO AT THE DIP
Preparing to come along side during an unrep.
3. ROMEO CLOSED UP
Commencing our approach on the oiler.
4. ROMEO HAULED DOWN
When the messenger is in hand.
5. PREP AT THE DIP
15 minutes prior to breaking away from unrep.
6. PREP CLOSED UP
Disengaging final unrep station.
7. PREP HAULED DOWN
All lines clear.
8. BRAVO AT THE DIP
Temporarily stopped pumping.
9. BRAVO CLOSED UP
Commenced pumping.
10. BRAVO HAULED DOWN
Completed pumping.
11. COLLISION
Crashing into another ship.
12. AGROUND
Crashed into land.
Ships cannot turn on a dime so there is an equation to determine when a ship needs to start its turn to be able to arrive exactly on the next appropriate course.
14. PIVOT POINT
There is a point on the ship that doesnt move while in a turn. Essentially the rest of the ship pivots around this point in a turn. Just like when playing basketball on your pivot foot.
15. ACCELERATION/DECELERATION
Tables based on the ships characteristics that tell the Conning Officer and Lee Helmsman how many RPMs = how many knots they want to drive.
16. TURNING CIRCLE
Table based on the ships characteristics that tells us how big of a circle we will make based on various speeds and rudder orders.
17. SWING CIRCLE
To determine the swing circle you must take the amount of anchor chain used and add it to the length of the ship. This will essentially give you where the stern of the ship spins around on the anchor chain while anchored.
18. DRAG CIRCLE
To determine the drag circle you must take the amount of anchor chain used and add it to the distance from the bull nose to the pelorus on the bridge. This will essentially give you where the bridge spins around on the anchor chain while anchored.

63. LATITUDE/LONGITUDE
• Latitude lines run horizontally East to West and are used to measure distance.
• Longitude lines run North to South and are used to measure time.
64. SET/DRIFT
• Set is the direction that you have been pushed off course by wind, current.
• Drift is the Speed that you have been pushed off course.

68. IALA (A/B) BUOYAGE SYSTEM
When pulling into US ports IALA B is used and the red buoys will be on the right when pulling into port (Red, Right, Returning). When pulling into most foreign ports we use IALA A where the red buoys will be on the right when you are leaving a port (Red, Right, Reaving).
