Question 1

A vessel at anchor in or near an area of restricted visibility rings the bell rapidly for about 5 seconds at intervals of not more than 1 minute, and if she is 100 metres or more in length, the bell signal is given in the forepart and is followed immediately by the rapid sounding of the gong for about 5 seconds in the after part.

Accepted Answer

True True. Rule 35(g) - the gong requirement for vessels 100m+ ties back directly to the Rule 33(a) equipment requirement, giving an approaching vessel an audible clue to both the presence and the approximate length/orientation of the anchored vessel.

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.
