Question 1

Rule 13 (Overtaking) defines an overtaking vessel as one coming up on another from a direction more than 22.5 degrees abaft the other vessel's beam — and once a vessel is classed as overtaking, it remains the give-way vessel until it is finally past and clear, even if the bearing later changes.

Accepted Answer

True True. Rule 13(c) and (d) confirm that any subsequent change in bearing between the two vessels does not make the overtaking vessel a crossing vessel for the purposes of the Rules, nor relieve it of the duty to keep clear until it is finally past and clear.

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.
