Question 1

Under Rule 18, how does a power-driven vessel's obligation toward a vessel engaged in fishing compare to her obligation toward a sailing vessel?

Accepted Answer

A power-driven vessel underway must keep out of the way of both a vessel engaged in fishing and a sailing vessel (as well as vessels not under command or restricted in ability to manoeuvre) — fishing vessels are recognised as having limited manoeuvrability due to their gear Rule 18 groups vessels engaged in fishing alongside sailing vessels, not under command, and restricted in ability to manoeuvre, as vessels that a power-driven vessel underway must generally keep out of the way of — reflecting the practical limitations fishing gear places on manoeuvring.

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.
