(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?
(a) Any vessel that has an engine to propel herself through the water
(Q) Describe a sailing 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:-
- The state of visibility
- Density of traffic
- How manoeuvrable your vessel is, and how quick you can stop your vessel
- The glare of your lights or light from the shore, you might not see the harbour entrance
- Weather, sea state and any navigation hazards
- 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

(Q) What are the dangers with radar plotting?
(a) Time is being wasted and could put your vessel into a collision course
(Q) If the bearings are steady, is there a risk of collision?
(Q) If the bearings are not steady, could there still be a risk of collision?
(Q) What situations?
(a) With a large vessel, a long tow or a close quarter situation.
(Q) If plotting a vessel towing a vessel towing another vessel with the length of tow being 2 miles long, what are you going to take bearings of?
(a) The stem of the towing vessel and the stern of the vessel being towed, everything in between is 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

(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) Have Due regards to the prevailing condition
(Q) What does Rule 19 (d) say?
(a) A vessel which detects by radar alone the presence of another vessel shall determine if a close-quarter situation is developing and/or risk of collision exists. if so she shall take avoiding action in ample time, providing that when such action consists of an alteration of course, so far as possible the following shall be avoided
(Q) What does Rule 19 (d) Part (i) say?
(a) Avoid an alteration to port for a vessel forward of the beam, other than for a vessel being overtaken
(Q) What does Rule 19 (d) Part (ii) say?
(a) Avoid an alteration towards a vessel abeam or abaft the beam
(Q) What does Rule 19 (e) say?
(a) Except where it has been determined that a risk of collision does not exist, every vessel which hears apparently forward of her beam, the fog signal of another vessel, or which cannot avoid a close-quarters situation with another vessel forward of her beam, shall reduce her speed to a minimum at which she can be kept on her course. Shall if necessary take all her way off and in any event navigate with extreme caution until danger of collision is over.
Rule 23. Power-Driven Vessels
(Q) A Power-driven Vessel – UNDERWAY, what Navigation Lights does he switch off if he is stopped and making no-way through the water?

- Not Under Command (Red light over a Red Light – 2 metres apart)
- A Vessel engaged in Pilotage duties (White light over a Red Light – 2 metres apart)
(Q) How can you tell a Power-driven vessel is Makingway?
(a) By taking a series of Compass, Radar & Visual Bearings (visual Bearings being most accurate)
Rule 34. Manoeuvring and Warning Signals
(Q) 1,2,3 & 5 Short and Rapid blasts on the ships whistle, what condition of visibility are these sound signals used?
(a) When vessels are in sight of one another
(Q) Does that mean clear visibility?
(a) No, you can still see a vessel when it is hazy, when you can see the vessel visually then you use this Rule and not Rule 35. Sound Signals in Restricted Visibility
