PART A
Which rule states that the collision regulations apply to all vessels upon the high seas and all waters connected to the high seas and navigable by seagoing vessels?
Rule 1
What does rule 5 state?
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.
What color and where are sidelights placed?
'Sidelights' means a green light on the starboard side and a red light on the port side each showing an unbroken light over an arc of the horizon of 112.5 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on its respective side. In a vessel of less than 20 meters in length the sidelights may be combined in one lantern carried on the fore and aft centreline of the vessel.
How long does a "short blast" last for?
about 1 second
A white light placed as nearly as practicable at the stern showing an unbroken light over an arc of the horizon of 135 degrees and so fixed as to show the light 67.5 degrees from right aft on each side of the vessel is known as what?
Sternlight
What does rule 2 cover?
The responsibility of the master, owner, and crew to comply with the COLREGs.
Every vessel shall at all times proceed at a safe speed is what rule?
Rule 6
What color is the towing light?
Yellow
How long does a "prolonged blast" last for?
4-6 seconds
A power-driven vessel underway shall keep out of the way of what four vessels?
1. a vessel not under command;
2. a vessel restricted in her ability to manoeuvre;
3. a vessel engaged in fishing;
4. a sailing vessel.
A vessel which though some exceptional circumstance is unable to manoeuvre as required by the COLREGs and is therefore unable to keep out of the way of another vessel is described by what term?
Not under command
Sailing vessels and vessels less than how many meters in length are obliged to not impede the passage of vessels which can safely navigate only within a narrow channel or fairway?
20
What should the visibility of the masthead light be on a vessel of 50 m or more?
6 miles
If a power-driven vessel is underway and is in sight of another vessel, one short blast means
What does Rule 14 state?
When two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk of collision each shall alter her course to starboard so that each shall pass on the port side of the other.
The word "underway" means what?
A vessel is not at anchor or made fast to the shore or aground.
Complete the statement from Rule 9: A vessel proceeding along the course of a narrow channel or fairway shall keep.......
as near to the outer limit of the channel or fairway which lies on her starboard side as is safe and practicable.
an all-round white light or a cone apex upwards in the direction of the gear
In or near an area of restricted visibility, whether by day or night, a power-driven vessel making way through the water shall sound at intervals of not more than 2 minutes one what?
prolonged blast.
When is a vessel deemed to be overtaking another vessel?
A vessel shall be deemed to be overtaking when coming up with another vessel from a direction more than 22.5 degrees abaft her beam, that is, in such a position with reference to the vessel she is overtaking, that at night she would be able to see only the sternlight of that vessel but neither of her sidelights.
Name three situations that fall under the term "Vessels restricted in ability to manoeuvre".
1.a vessel engaged in laying, servicing or picking up a navigation mark, submarine cable or pipeline;
2.a vessel engaged in dredging, surveying or underwater operations;
3. a vessel engaged in replenishment or transferring persons, provisions or cargo while underway;
4. a vessel engaged in the launching or recovery of aircraft;
5. a vessel engaged in mineclearance operations;
6. 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.
A vessel using a traffic separation scheme shall abide by what three points?
1. proceed in the appropriate traffic lane in the general direction of traffic flow for that lane;
2. so far as practicable keep clear of a traffic separation line or separation zone;
3. normally join or leave a traffic lane at the termination of the lane, but when joining or leaving from either side shall do so at as small an angle to the general direction of traffic flow as practicable.
A vessel restricted in her ability to manoeuvre, except a vessel engaged in mineclearance operations, shall exhibit:
1. three all-round lights in a vertical line where they can best be seen. The highest and lowest of these lights shall be red and the middle light shall be white;
2. three shapes in a vertical line where they can best be seen. The highest and lowest of these shapes shall be balls and the middle one a diamond;
3. when making way through the water, a masthead light or lights, sidelights and a sternlight in addition to the lights prescribed in subparagraph (i);
4. when at anchor, in addition to the lights or shapes prescribed in subparagraphs (i) and (ii), the light, lights or shape prescribed in Rule 30.
A vessel not under command, a vessel restricted in her ability to manoeuvre, a vessel constrained by her draught, a sailing vessel, a vessel engaged in fishing and a vessel engaged in towing or pushing another vessel shall sound what?
one prolonged followed by two short blasts of intervals of not more than 2 minutes.
A vessel when engaged in trawling, by which is meant the dragging through the water of a dredge net or other apparatus used as a fishing appliance, shall exhibit
-two all-round lights in a vertical line, the upper being green and the lower white, or a shape consisting of two cones with their apexes together in a vertical line one above the other;
-a masthead light abaft of and higher than the all-round green light; a vessel of less than 50 metres in length shall not be obliged to exhibit such a light but may do so;
-when making way through the water, in addition to the lights prescribed in this paragraph, sidelights and a sternlight.
