Performance requirement

Behavior Standard
The student will: During assessment, the student shall, at a minimum:

Carry out the helm command steer 342 and steady the vessel on the new course. See Note 1.

  1. Repeat the order;
  2. Turn the helm in the direction of the fewest degrees to the ordered course using no more than 15° of rudder;
  3. Report the ship’s heading, while swinging, in each 10° increment;
  4. Reduce the rudder angle as the vessel approaches the course;
  5. Steady on the ordered course with less than 5° of overshoot; and
  6. State: “Steady on course [ordered course].”

Carry out the helm command steer 342 and steer the vessel on course using the gyro-compass. See Note 2.

  1. Repeat the helm order
  2. When steady on course, state “Steering [three four two];” and
  3. Steer the course ordered within ±3° (open ocean), and ±2° (near coastal) to demonstrate proficiency.

Carry out the helm command Right (starboard) rudder.

  1. Repeat the order;
  2. Immediately turn the helm to right (starboard);
  3. Stop turning the helm when the rudder angle indicator reads right (starboard) 10°;
  4. State: “The rudder is right (starboard) 10°;” and
  5. State the vessel’s heading in 10° increments until a new heading is provided (e.g., “passing 320°”).

Carry out the helm command Left (port) rudder.

  1. Repeat the order;
  2. Immediately turn the helm to left (port);
  3. Stop turning the helm when the rudder angle indicator reads left (port) 20°;
  4. State: “The rudder is left (port) 20”, and
  5. State the vessel’s heading in 10° increments until a new heading is provided (e.g., “passing 060°”).

Carry out the helm command Rudder hard over.

  1. Repeat the order;
  2. Immediately turnsthe helm to right (starboard);
  3. Stop turning the helm when the rudder angle indicator reads maximum right (starboard) rudder;
  4. Ensure that the rudder is not jammed against the stops; and
  5. State: “The rudder is hard right (starboard).”

Carry out the helm command Ease the rudder when the rudder is more than 5° right (starboard) or left (port).

  1. Repeat the order;
  2. Immediately turn the helm to reduce the rudder angle;
  3. Stop turning the helm when the rudder angle indicator reads right (starboard) or left (port) 5°; and
  4. State: “The rudder is right (starboard) or left (port) 5.”

Carry out the helm command Midships the wheel when the rudder is either right (starboard) or left (port).

  1. Repeat the order;
  2. Immediately turn the helm to reduce the rudder angle;
  3. Stop turning the helm when the rudder angle indicator reads zero; and
  4. State: “The rudder is midships.”

Carry out the helm command Shift your rudder when the rudder is 15° right (starboard).

  1. Repeat the order;
  2. Immediately turn the helm to the left (port);
  3. Stop turning the helm when the rudder angle indicator reads left (port) 15°;
  4. State: “The rudder is left (port) 15;” and
  5. State the vessel’s heading in 10° increments until a new heading is provided (e.g., “passing 060°”).

Carry out the helm command Meet her or, check her during a turn.

  1. Repeat the order;
  2. Immediately turn the helm to reduce the rudder angle;
  3. Apply counter rudder until the vessel stops turning;
  4. Ease the wheel to midships; and
  5. State: “The vessel’s heading is …”

Carry out the helm command Steady as She Goes.

  1. Repeat the order;
  2. Note the heading when the command was given;
  3. Immediately apply counter rudder to stop any swing of the ship;
  4. Steer the heading noted; and
  5. State: “Steady, heading …”

Carry out the helm command, Nothing to the right (starboard) See Note 3.

  1. Repeats the order;
  2. Note the heading when the command was given;
  3. Immediately apply counter rudder to stop any swing of the ship to the right (starboard); and
  4. Steer the heading noted, but with no error to the right permitted.
