  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

  11. COLLISION
    Crashing into another ship.
  12. AGROUND
    Crashed into land.
  13. ADVANCE / TRANSFER
    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.
