(a) Is a vessel through the nature of her work; she is unable to deviate from her course she is following.

(Q) Describe a “vessel constrained by her draught”?

(a) Is a power-driven vessel, because of her draught in relation to the depth of water she is in, cannot deviate from the course she is following

(Q) Describe the word “Underway”?

(a) When a vessel is not at anchor, aground or made fast to the shore, and is only going through the water by tide and/or wind.

(Q) Describe the word “Making way”?

(a) When a vessel is being propelled through the water by engine propulsion, sails or oars

(Q) In the Rules of the road, in some rules the word “vessel” comes up, but what would you say a vessel is?

(a) Any type of watercraft than can carry personnel.

(Q) Describe a power-driven vessel?

Rule 5 Look-out.

(Q) Describe rule 5 look-out?

(a) By keeping a good look-out using eyes, ears and by using all navigation aids including radios for listening out for navigation warnings, so you can appraise any situation ahead of you.

Rule 6 Safe Speed.

(Q) Describe a safe speed by all vessels?

(a) Every vessel shall go at a safe speed so that you can stop your vessel in half the distance you can see and use the other half to manoeuvre away from danger, taking the following factors into account: –

By all vessels:-

  1. The state of visibility
  2. Density of traffic
  3. How manoeuvrable your vessel is, and how quick you can stop your vessel
  4. The glare of your lights or light from the shore, you might not see the harbour entrance
  5. Weather, sea state and any navigation hazards
  6. The draught of your own vessel
(Q) Describe a safe speed by vessels with operational radar?
  • The limitations of your radar
  • The scale in use ( too small a scale could be hiding targets )
  • Weather, sea and rain clutter ( target could be hiding in clutter )
  • Ice, small vessels not detected by radar
  • Vessels detected by radar
  • Determine the range of other vessels

Rule 7 Risk of Collision.

(Q) What would you use to determine a risk of collision?

Rule 8 Action to avoid collision.

(Q) What 4 actions can you take to avoid a collision?
  • An early and bold alteration of course, as long as you do not put your vessel into another close quarter situation/risk of collision with another vessel
  • Slow your vessel down
  • Stop your vessel
  • Come astern with your vessel
(Q) Why are you always making an alteration of course, why do you not stop your vessel?

(a) To make sure the risk of collision/close quarter situation is taken out, also the other vessel ill see the change of aspect of your vessel (Visually and by radar)

(Q) If you make an alteration of course, what have you to watch out for?

(a) That you don not put yourself into a close quarter situation with another vessel

(Q) If you make an alteration of course, why is it dangerous to make a series of small alterations

(a) Because you could go into a close quarters situation/risk of collision

(Q) If you’re unsure about what to do in a situation, what’s the best thing to do?

(a) Slow your vessel down, best to stop your vessel altogether.

Rule 9 Narrow Channels.

(Q) What side of the narrow channel would you keep?

(a) The starboard side of the narrow channel as long as your vessel is in safe water.(Morse “G”) (2 prolonged blasts followed by 1 short blast on the whistle

Rule 10 Traffic Separation Schemes.

(Q) How do you join a lane?

(a) At the start of a lane or at a small an angle as possible to the lane.

(Q) How do you leave a lane?

(a) At the end of a lane or at a small an angle as possible to the lane.

(Q) How do you cross the lanes?

(a) At 90 degrees to the general flow of traffic (DO NOT SAY TO THE LANE)

(Q) Why 90 degrees?

(a) Because it’s the quickest way across, and vessels in the lane can see the aspect of your vessel.

(Q) If crossing a lane, what 3 vessels do not impede any vessel using a lane?

(a) A fishing vessel, a sailing vessel and a power-driven vessel under 20metres.

(Q) What vessels can use the inshore zone?

(a) A power-driven vessel under 20 metres, sailing vessels, fishing vessels, vessels going to or from a port, going from port to port in the scheme, going into anchor to do emergency repairs, to avoid immediate danger, to lay submarine cables or to do repairs to buoys within the scheme.

(Q) What vessels can use the traffic separation zone?

(a) Fishing vessels, anchor for emergency repairs, crossing vessels, to avoid immediate danger, to lay submarine cables or to do repairs to buoys within the scheme.

(Q) Where can you anchor in a scheme?

(a) Anywhere, as long as it’s to do emergency repairs, try and avoid anchoring in the lanes and at the terminations.

(Q) What would you do if you had to stop your main engine to do emergency repairs in a lane and had to anchor?

(a) Call up the port and advise them, also put out a security warning other vessels that you’re at anchor, put up anchor lights and daytime signal.

(Q) Where can you fish in the scheme?

(a) Anywhere, but if fishing in a lane then go with the flow of traffic, and try and avoid fishing at the terminations.

(Q) Would you fish in a traffic separation scheme?

(a) This is a personnel question, there is a lot of large traffic there; you would be putting your crew and vessel into dangerous situations.

(Q) Could a supertanker leave a lane at 90 degrees come into the inshore zone to a pilot station, pick up a pilot and then cross to the opposite inshore zone at 90 degrees?

(a) No, he would have to leave the lane at a small an angle as possible to the lanes.

(Q) If you’re in a power-driven vessel, crossing a scheme and on your port bow is another power-driven vessel in a lane, the bearing are steady and the distance is closing, what are you going to do?

(a) First find out length of vessel you are in.

(Q) Does it matter what size the power-driven vessel is that you’re in?

(a) Yes, if under 20 metres and crossing a lane, then you would have to give way to every vessel in the lane.

(Q) Your in a 30 metres power-driven vessel crossing a lane, and there is a power-driven vessel on your port bow in a lane, the bearings are steady and the distance is closing, what are you going to do?

(a) Stand-on with caution, maintaining your course and speed

(Q) How would the power-driven vessel leave the lane?

(a) He would make an early and bold alteration to starboard sounding 1 short blast on the whistle indicating he is altering to starboard.

(Q) Would he line up your stern and go around it?

(a) No, this would be a close quarter situation and could make you alter your course and put into a collision course with another vessel.

(Q) After the vessel came around your stern, how would he get back into the lane?

(a) At a small angle as possible to the general flow of traffic.

(Q) If you where in any vessel, just outside the scheme, would you manoeuvre here?

(a) No, it says if not using the scheme, then to give it a wide a margin as possible.

(Q) If you’re fishing in a lane, and there is a power-driven vessel overtaking you, what are you going to do?

(a) Stand-on with caution, you have to use rule 13 Overtaking.

(Q) If you’re crossing a lane in a fishing vessel and any vessel is on your port bow in a lane, the bearings are steady and the distance is closing, what are you going to do?

(a) If you’re crossing and the bearings are steady, then you have to give-way to all vessels in a lane.

(a) 2 power-driven vessels.

(Q) In a head-on situation between 2 power-driven vessels, how do you know it’s a head-on situation at night?

(a) Because you would see his masthead light in between his sidelights.

(Q) What action will you take with 2 power-driven vessels in a head-on situation?

(a) Both vessels will sound 1 short blast on the whistle and make an early and bold alteration to starboard.

(Q) What action will you take if you’re in a power-driven vessel, and in a head-on situation with a fishing vessel, also what action would the fishing vessel take?

(a) You will sound 1 short blast on the whistle and make an early and bold alteration to starboard, the fishing vessel will stand-on with caution because he is most hampered.

(Q) May he sound the identity signal when vessels are in sight of one another?

(a) No, this is only to be sounded in Restricted Visibility

(Q) Is there a time length for the Pilots identity signal (I.E. not exceeding 2 minutes)?

(a) No, there is no time limit, he may sound the identity signal as and when he wants

(Q) Name the vessels with a hampered fog signal (1 Prolonged and 2 short)?

(i) Sailing Vessel
(ii) Fishing vessels (Trawler & Fishing other than Trawling)
(iii) Not Under command
(iv) Restricted in her ability to manoeuvre
(v) Constrained by her Draught
(vi) Minesweeper

(viii) Restricted in her ability to manoeuvre engaged in towing
(ix) A vessel engaged in pushing another vessel ahead
(x) A Fishing vessel other than trawling fishing while at anchor (Anchor Seine-net)
(xi) Restricted in her ability to manoeuvre while at anchor

(Q) A Power-driven vessel has 2 different Fog signals, what are they?

(a)  If Underway – Two Prolonged blasts on the ships whistle at intervals not exceeding two minutes

    • Hi Vijesh, the definition of Underway is mentioned very clearly in ROR which says the vessel is underway when she is not at anchor, made fast ashore or aground which clearly means a vessel drifted by current is also underway whereas to be called making way in simple words, as long as the thrust is being generated by the propeller, its making way. In this Case the engine may have been stopped but the propeller may still be rotating. In making way, the wake produced by the propeller can be seen on the surface of the sea.
      In case you have doubts & queries, please drop your question on home page (the option for dropping your question is provided)

    • Underway : Should Not be secured by any means with land
      Making way : Making Headway ( Using propullsion ) or you moving a head by Current/wind with standing

      • @prasanna: Making Way & making headway has little difference. In making way, it does not matter in which direction the ship is heading as long as the movement is because of the propeller thrust. making headway simply means the ship is moving ahead because of the propeller thrust & underway as you rightly said the vessel is not secured with ground, hence it can be drifted by current. To sum up,if a vessel is making way that means for sure it is underway. but if she is underway, its not necessary that she is making way.

    • Making way refers to the vessel is in movement in water. Under way also refers to any time when the vessel is in water, no matter whether the vessel is in movement or stationary in water. It just needs to satisfy the condition ‘not anchored’. It is possible for a vessel to be under way, but not making way.
