Question 1

A vessel constrained by her draught (Rule 28) is proceeding along a deep-water route, and a smaller power-driven vessel is crossing from her starboard side, putting the smaller vessel in the "give-way" role under Rule 15's normal application (vessel with the other on her own starboard side keeps clear). Does the constrained-by-draught vessel's status change this outcome?

Accepted Answer

No — Rule 28 (constrained by draught) does not appear in Rule 18's list of vessels that others must keep out of the way of, so the normal Rule 15 crossing analysis (smaller vessel gives way) generally still applies — however the constrained vessel's very limited ability to deviate (due to depth) is a practical factor the crossing vessel should weigh under Rule 2 and good seamanship This is a commonly misunderstood point — Rule 18 does not list "constrained by draught" among the categories that power-driven vessels must keep clear of (unlike not under command, restricted in ability to manoeuvre, fishing, and sailing vessels). The normal Rule 15 analysis applies, but Rule 2 (ordinary practice of seamen / special circumstances) means the crossing vessel should still factor in the constrained vessel's very limited room to manoeuvre.

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.
