Question 1

A vessel of less than 12 metres in length, when aground, is not required to exhibit the two all-round red lights or the three balls otherwise required for a vessel aground, but must still show her normal anchor light or shape.

Accepted Answer

True True. Rule 30(f) exempts vessels under 12m from the extra aground signals in Rule 30(d)(i) and (ii) only - she must still comply with Rule 30(a) or (b) for the basic anchor light/shape, since 'aground' does not exempt her from the anchor-light requirement, it merely spares her the additional red lights or balls that warn of being fast on the bottom.

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.
