Question 1

A vessel of less than 7 metres in length, when at anchor and not in or near a narrow channel, fairway, anchorage, or where other vessels normally navigate, is not required to exhibit the anchor lights or shape prescribed by Rule 30.

Accepted Answer

True True. Rule 30(e) provides this exemption for very small vessels anchored clear of normal traffic - reflecting that the practical collision risk they pose at anchor in an open area is minimal, while still requiring full compliance if anchored anywhere traffic might reasonably pass.

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.
