Question 1

Which of the following is a factor ALL vessels must take into account when determining safe speed?

Accepted Answer

The state of visibility. Rule 6 lists factors for ALL vessels: state of visibility; traffic density; manoeuvrability; at night, background lights; state of wind, sea and swell; proximity of navigational hazards; draught in relation to available depth. The additional factors for radar-equipped vessels include: range scale in use, sea clutter, detection limitations. State of visibility applies universally.

Question 2

Rule 6 lists additional factors for vessels with operational radar to consider when determining safe speed. Which of the following is one of those additional factors?

Accepted Answer

The characteristics, efficiency and limitations of the radar equipment. Rule 6(b), additional factors for radar-equipped vessels: characteristics, efficiency and limitations of radar equipment; constraints imposed by radar range scale in use; effect on radar detection of sea state, weather, and other sources of interference; possibility that radar may fail to detect small vessels, ice or other floating objects; number and position of vessels detected; more exact assessment of visibility possible when radar is in use.

Question 3

A vessel proceeds at high speed in heavy traffic but clear visibility. What principle applies?

Accepted Answer

Traffic density must be considered when determining safe speed.. Rule 6 includes traffic density as key factor.
