Question 1

What additional light(s) does Rule 24 require a power-driven vessel to show when towing another vessel astern, compared to a vessel not towing?

Accepted Answer

A second masthead light (in a vertical line above or below the regular masthead light, depending on the length of the tow) in addition to sidelights, sternlight and a towing light (yellow, of the same characteristics as a sternlight) positioned above the sternlight Rule 24 requires towing vessels to show additional masthead light(s) (number depending on tow length) plus a yellow towing light above the sternlight, so other vessels can identify both that towing is occurring and (via the masthead light arrangement) something about the length of the tow.

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.
