Define “vessel engaged in fishing”
Any vessel fishing with nets, lines, trawls or other fishing apparatus which restricts manoeuvrability, but does not include a vessel fishing with trolling lines or other fishing apparatus which do not restrict manoeuvrability.
Define “vessel not under command”
A vessel through some exceptional circumstance is unable to manoeuvre as required by these Rules and is therefore unable to keep out of the way of another vessel.
Define “vessel restricted in her ability to manoeuvre”
A vessel which from the nature of her work is restricted in her ability to manoeuvre as required by these Rules and is therefore unable to keep out of the way of another vessel.
Define “vessels restricted in their ability to manoeuvre” shall include but not be limited to:
(i) a vessel engaged in laying, servicing or picking up a navigation mark, submarine cable or pipeline;
(ii) a vessel engaged in dredging surveying or underwater operations;
(iii) a vessel engaged in replenishment or transferring persons, provisions or cargo while underway;
(iv) a vessel engaged in the launching or recovery of aircraft;
(v) a vessel engaged in mine clearance operations;
(vi) a vessel engaged in a towing operation such as severely restricts the towing vessel and her tow in their ability to deviate from their course.
Define “vessel constrained by her draught”
A power-driven vessel which, because of her draught in relation to the available depth and width of navigable water, is severely restricted in her ability to deviate from the course she is following.
Define “restricted visibility”
Any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, sandstorms or any other similar causes.
Define “underway”
A vessel is not at anchor, or made fast to the shore, or aground.
Define Lookout
Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision.
Define Safe speed
Every vessel shall at all times proceed at a safe speed so she can take proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and conditions.
What are the factors determining safe speed by all vessels?
(VD Makes Little Willies Drip)
(i) the state of visibility;
(ii) the traffic density including concentrations of fishing vessels or any other vessels;
(iii) the manoeuvrability of the vessel with special reference to stopping distance and turning ability in the prevailing conditions;
(iv) at night the presence of background light such as from shore lights or from backscatter of her own lights;
(v) the state of wind, sea and current, and the proximity of navigational hazards;
(vi) the draught in relation to the available depth of water.
What are the factors determining safe speed by vessels with operational radar?
(Charlie Can’t Eat Pie No More)
(i) the characteristics, efficiency and limitations of the radar equipment;
(ii) the constraints imposed by the radar range scale in use;
(iii) the effect on radar detection of the sea state, weather and other sources of interference
(iv) the possibility that small vessels, ice and other floating objects may not be detected by radar at an adequate range;
(v) the number, location, and movement of vessels detected by radar;
(vi) the more exact assessment of the visibility that may be possible when radar is used to determine the range of vessels or other objects in the vicinity.

What is the order of vessels to keep out of the way of one another in Rule 18?
Overview of Rule 19 Conduct of vessels in restricted visibility
(a) This rule applies to vessels not in sight of one another when navigating in or near an area of restricted visibility.
(b) Every vessel shall proceed at a safe speed adapted to the prevailing circumstances and conditions of restricted visibility. A power-driven vessel shall have her engines ready for immediate manoeuvre.
(c) Every vessel shall have due regard to the prevailing circumstances and conditions of restricted visibility when complying with the Rules of Section 1 of this part.
(d) A vessel which detects by radar alone the presence of another vessel shall determine if a close-quarters situation is developing and/or risk of collision exists. If so, she shall take action to avoid in ample time, provided that when such action consists of an alteration of course, so far as possible the following shall be avoided:
(i) An alteration, of course to port for a vessel forward of the beam other than for a vessel being overtaken;
(ii) An alteration, of course, towards a vessel abeam or abaft the beam
(e) Except where it has been determined 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 the minimum at which she can be kept on her course. She shall if necassary take all her way off and in any event navigate with extreme caution until danger of collision is over.
