Question 1

Rule 25(d) makes a special provision for sailing vessels under a certain length and rowing boats regarding lights. What does it allow?

Accepted Answer

A sailing vessel of less than 7 metres in length, and a vessel under oars, may, if practicable, exhibit the lights prescribed for sailing vessels — but if not, shall have ready at hand an electric torch or lighted lantern showing a white light to be exhibited in sufficient time to prevent collision Rule 25(d) provides a practical alternative for very small craft that may not be able to fit/power standard navigation lights — a torch or lantern shown in time to prevent collision is acceptable where full lighting is impracticable.

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.
