  1. Describe UNREP
    Underway replenishment a broad term applied to all methods of transferring fuel, munitions, supplies, and personnel from one vessel to another while underway
  2. Describe VERTREP
    Vertical replenishment carried out by helicopters
  3. Describe CONREP
    Connected replenishment. When two or more ships steam side by side and the hoses and lines are connected for replenishment
  4. Replenishment speed
    12-16 knots
  5. What kind of breakaway does CVN class ships use
    Accelerated standard breakaway which is maximum speed but small rudder orders 1/2 degree at a time.
  6. Purpose of special sea and anchor detail
    To provide max safety when ship is to be maneuvered in close range to land or another ship within 1 mile.
  7. Low visibility detail
    Fog or reduced visibility 3 miles or less
  8. Who gives orders to abandon ship and what are the three phases
    • CO
    • 1. Prepare all hands abandon ship
    • 2. All hands abandon ship, except securing/salvage
    • 3. Secure salvage, and abandon ship
  9. Words to be passed for an abandon ship
    • Nearest land in degrees magnetic
    • Land is friendly/hostile
    • Distance in nautical miles
    • True wind
    • Sea state and temperature
    • Water depth
    • Life expectancy in the water
  10. What life rafts onboard
    MK-6, 25 man raft. 252 total
  11. Three types of man overboard recovery
    • Airborne
    • Small boat
    • Shipboard
  12. Define collision
    Act or instance of colliding. To come together with solid or direct impact
  13. Define aground
    On or onto the shore or the bottom of a body of water, concern is breaching the hull of a ship
  14. True bearing vs relative bearing
    True bearing is the direction from one point on the earth to another point in degrees from 000-360 clockwise using true north as a guiding reference point

    Relative bearing the direction in degrees from 000-360 relative starting with the bow of the ship at 000 degrees relative continuing clockwise to the starboard beam at 090 to the stern 180
  15. 5 navigation lights:
    • 1. Port
    • 2. Starboard
    • 3. Forward mast
    • 4. Aft mast
    • 5. Stern light
    • 1. Red
    • 2. Green
    • 3. White
    • 4. White
    • 5. White (blue during night flight operations)
  16. Shape/ lights for restricted maneuvering
    • Red over white over red
    • Ball diamond ball
  17. Light man overboard
    Red over red
  18. Shape/ light used when not under command
    • Red over red
    • Ball ball
  19. Shape/ light vessel aground
    • Red over red
    • Ball ball ball
  20. Describe stadimeter
    An instrument used to determine distance to an object of known height
  21. Describe sextant
    A marine sextant is used for celestial navigation. It measures the height of observation of celestial bodies. This info used in conjunction with exact time of observation along with mathematical calculations produces the observers exact location
  22. Describe chronometer
    A very accurate clock
  23. Describe gyrocompass
    This electronic compass uses internal gyros to determine true north
  24. Describe Fathometer
    An electric instrument used to determine the depth of the water beneath the keel of the ship
  25. Describe GPS
    Global Positioning System. Based on 24 orbital satellites, 21 are active at all time.
  26. Describe Barometer
    Instrument used to determine atmospheric pressure
  27. Describe psychrometer
    Instrument measures combination of wet and dry thermometer to determine amount of moisture in the air
  28. Describe telltale panel
    Lighting indication panel in the pilot house shows status of navigation running lights
