Question 1

Your examiner asks: "Rule 36 permits a vessel to attract the attention of another vessel. What does this actually allow, and what must you be careful not to do?"

Accepted Answer

Rule 36 permits any light or sound signal that cannot be mistaken for any signal authorised elsewhere in the Rules, or the use of a searchlight directed toward the danger, to attract attention — the key restriction is that whatever signal you use must not be confused with a navigation light, a manoeuvring signal, or a distress signal, and must not embarrass any vessel by shining a light in a way that impairs her vision Rule 36 is a short, easily overlooked rule — it's the basis for using a searchlight or an improvised signal to get another vessel's attention (e.g. a vessel that seems unaware of your presence), but it comes with the explicit caution against creating confusion with prescribed signals or dazzling another vessel's bridge team. Examiners like this rule because it tests whether a candidate understands the difference between "permitted" and "unrestricted."

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.
