Question 1

True or False: because Karin Høj had no voyage data recorder and there were no survivors, the investigation was able to establish exactly what actions its crew took before the collision.

Accepted Answer

False — the investigation could not establish Karin Høj's crew's actions before the collision With no VDR and no survivors from Karin Høj, the investigation could not determine what its crew did or didn't do before the collision. What is established is that neither vessel had a dedicated lookout posted, and that Scot Carrier's second officer altered course into Karin Høj's position without checking for traffic.

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.
