Question 1

As the give-way vessel under Rule 15, what should your immediate decision be?

Accepted Answer

Take early and substantial action to keep well clear, in compliance with Rule 8 — a bold, readily apparent alteration of course to starboard (given the geometry) so as to pass well clear on the other vessel's stern, avoiding a series of small alterations As give-way vessel you are obliged to act, and Rule 8 requires that action to be early, substantial and readily apparent — a small or late alteration risks being misread by the other vessel or leaving too little margin if your assessment is slightly off.

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.
