orange and more readily available than MK1; serves same purpose

buoyant object to hold on to for man overboard

will transmit a continuous radio signal in event of ship sinking or other extremis event; used by search and rescue teams to quickly locate and render aid

double-ended pair of HORNS used for securing a line or wire; always trip over these when running on Hospital Point

PAIR of heavy vertical cylinders, used for making fast lines led through chocks

strong cylindrical upright on a pier, about which a mooring line is placed

heavy fitting with smooth surfaces through which mooring lines are led

a metal plate with an eye attached to the deck to distribute a load over a large area

separate vertical machinery units or part of the anchor windlass around which lines are passed, commonly used in mooring and anchoring evolutions

general term that refers to both fiber and wire

rope that has been purposely sized, cut, spliced, or assigned to a function; measured by circumference; ex. braided, plaited, twisted

run at right angles from ship; control distance of ship from pier; bow line and stern line

control FORWARD movement of ship; lines 2 and 4

control AFT movement of ship; lines 3 and 5

in charge of bridge; reports directly to Commanding Officer for SAFE NAVIGATION and GENERAL OPERATION of ship

OOD under instruction; assistant

SAFE NAVIGATION of the ship; issues RUDDER and ENGINE commands to the helm and lee helm

shields secured around mooring lines to prevent rats from coming aboard ships

canvas or other material placed around mooring lines to prevent wear

maintains NAVIGATIONAL PICTURE for OOD

enlisted assistant to OOD for carrying out ship’s ROUTINE (plan of the day); also responsible for watch routine and instruction, behavior, and appearance of enlisted watchstanders

executes RUDDER orders

executes ENGINE orders

measures bearing (direction) to objects; normally located in PILOT HOUSE on the centerline pelorus

measures bearing (direction) to objects; normally located on BRIDGE WINGS

measures atmospheric pressure; low pressure = adverse weather

electronic chart primarily used by the OOD and QMOW to ensure the ship is in safe waters

distance obtained by radio wave

uses two LOGARITHMIC SCALES to determine distance to objects of known height

laser pulse of light; great for short distance calculations

trigonometric calculations

uses SONAR to measure depth of water from keel of ship to ocean floor

senior watchstander in the Combat Information Center (CIC); in charge of tactical employment and defense of ship; weapons systems

supervises the personnel on watch in the CIC

assist the TAO in maintaining tactical situational awareness; divided by specific warfare assignments…

• Surface Warfare Coordinator (SUWC)

• Anti-Air Warfare Coordinator (AAWC)

• Anti-Submarine Warfare Coordinator (ASWC)

in charge of the operations of the engineering plant while underway; reports directly to the Chief Engineer; reports directly to OOD for plant status & casualties

reports to the EOOW and operates/monitors equipment remotely from the Central Control Station (CCS); propulsion and auxiliaries control console operator

reports to EOOW and operates/monitors equipment remotely from Central Control Station (CSS); electrical plant control console operator

various positions within engineering plant to oversee multiple systems within ship; ONLY report to EOOW

What are the 4 parts of a standard command?

What are the 4 expressions of direction?

15 - standard

30 - full

35 - hard

15 - standard

25 - full

30 - hard

course change less than 10 degrees

place the rudder at 0 degrees

move rudder to OPPOSITE DIRECTION at the same amount

used to indicate order was not heard/understood

Pay attention!

helmsman reports the ship’s course at the time of the order

Wind, sea state, current, shallow water effect/squat

LATER; lines, anchors, tugs, engines, rudder

eliminates side force; all USN ships are equipped with this

goes INTO the propeller

comes OUT of the propeller (wash)

making headway = moves forward

making sternway = moves back

right full rudder

port engine ahead

starboard engine back

(when right side is against pier)

left full rudder

starboard engine ahead

port engine back

(when left side is against pier)

direction ship’s bow is pointing

direction ship is ACTUALLY traveling when you take into account environmentals

measured by pit sword (extends down from hull); measures flow of water going down the hull

difference between true and magnetic north in any given location

every steel ship has a magnetic field that can cause changes in a magnetic compasses; local magnetic signature of the ship
