Question 1

Two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk of collision. Under Rule 14 (Head-on Situation), what action should each vessel take?

Accepted Answer

Each vessel shall alter her course to starboard so that each shall pass on the port side of the other Rule 14(a) requires each vessel to alter course to starboard so that each passes on the port side of the other — option B and A describe the same outcome, but B is the precise wording of the rule. Note Rule 14(c): if there is any doubt whether such a situation exists, the doubt shall be resolved by assuming a head-on situation does exist.

Question 2

Rule 5 (Look-out) requires every vessel at all times to maintain a proper look-out by sight and hearing, as well as by all available means appropriate in the prevailing circumstances and conditions — and this duty applies even when the vessel is at anchor in a busy anchorage.

Accepted Answer

True True. Rule 5 applies 'at all times' and to 'every vessel'. A vessel at anchor in a busy anchorage still needs an effective look-out to detect drifting vessels, dragging anchors, or approaching traffic that may pose a risk of collision or contact.

Question 3

Under Rule 6 (Safe Speed), a vessel fitted with a fully operational radar and ARPA never needs to reduce speed in restricted visibility, because the equipment guarantees early detection of other vessels.

Accepted Answer

False False. Rule 6 explicitly lists radar capability as one factor to consider, but also requires accounting for the state of visibility, traffic density, manoeuvrability, and the limitations of radar (range scale, sea/rain clutter, blind sectors). Even a vessel with excellent radar must proceed at a speed that allows proper and effective action to avoid collision and to be stopped within a distance appropriate to the prevailing circumstances.
