Factual and Procedural Background
This appeal concerns a collision on 11 February 2015 between two large vessels: a laden Very Large Crude Carrier (VLCC), herein referred to as Vessel A, inbound to the port of Jebel Ali, and a laden container vessel, herein referred to as Vessel B, outbound from the same port. The collision occurred just outside the dredged channel entrance, within the pilot boarding area. Both vessels were equipped with Voyage Data Recorders, and their navigational tracks were agreed upon. The collision caused significant damage: over US$32 million to Vessel A’s bow and nearly US$4 million to Vessel B’s port bow.
The trial judge, Judge T, found that the crossing rules under the International Regulations for Preventing Collisions at Sea (1972) did not apply because one vessel was navigating in a narrow channel and the other was approaching to enter it, and because Vessel A was not on a sufficiently constant course, being engaged in waiting to embark a pilot. Instead, Vessel B was governed by the narrow channel rule, and Vessel A by the general duty of good seamanship. The judge apportioned liability 80% to Vessel B and 20% to Vessel A.
Permission to appeal was granted on certain grounds raised by Vessel B, challenging the applicability of the crossing rules and aspects of the apportionment of liability. The appeal was heard by the Court of Appeal, which considered three principal issues: the applicability of the crossing rules, the Respondent’s Notice, and causative potency in apportionment.
Legal Issues Presented
- Whether the crossing rules (Rules 15-17 of the Collision Regulations) apply where one vessel is navigating in a narrow channel and the other is approaching to enter it.
- Whether the Respondent’s Notice raises valid grounds to support the trial judge’s conclusion, including whether Vessel B caused the crossing situation and whether Vessel A was restricted in her ability to manoeuvre.
- Whether the trial judge erred in considering the extent of damage caused in assessing causative potency for apportionment of liability.
Arguments of the Parties
Appellant's Arguments (Vessel B)
- The trial judge erred in law by failing to apply the crossing rules and wrongly holding they did not apply where one vessel was in a narrow channel and the other was approaching it.
- The crossing and narrow channel rules could and should be applied concurrently without conflict.
- The judge wrongly imposed a requirement that the give-way vessel be on a sufficiently constant course for the crossing rules to apply.
- The judge erred by considering the extent of damage caused in determining causative potency, amounting to double-counting.
- On a hypothetical reversed scenario, the judge’s approach would create uncertainty and risk to safe navigation.
- The Elder Brethren’s advice was unclear on whether crossing rules applied in the hypothetical scenario and undermined the judge’s apportionment.
Respondent's Arguments (Vessel A)
- The trial judge was correct in holding the crossing rules inapplicable due to the risk of conflicting duties under the crossing and narrow channel rules.
- The decision is supported by authoritative precedents and principles emphasizing safety and good seamanship.
- The pilot boarding area’s special circumstances justified the application of narrow channel and good seamanship rules rather than crossing rules.
- The crossing rules require both vessels to be on sufficiently defined courses, which was not the case for Vessel A.
- Vessel A was not a vessel restricted in her ability to manoeuvre under the Collision Regulations.
- The judge’s approach to causative potency, including consideration of damage extent, was orthodox and supported by authority.
- The Elder Brethren’s advice aligns with the judge’s conclusions and does not undermine apportionment.

Court's Reasoning and Analysis
The Court began by examining the applicability of the crossing rules (Rules 15-17) in the context where one vessel was navigating within a narrow channel and the other was approaching it to enter. The Court agreed with the trial judge that applying the crossing rules simultaneously with the narrow channel rule (Rule 9) could create conflicting duties, which would be unsafe and contrary to the intent of the Collision Regulations. The Court found persuasive the reasoning in The Canberra Star and Kulemesin, which held that crossing rules do not apply in such circumstances to ensure continuity and safety of navigation.
The Court further accepted that Vessel A was not on a sufficiently constant course to engage the crossing rules, being effectively stationary or waiting to embark a pilot. The principle that both vessels must be on sufficiently defined courses for crossing rules to apply was endorsed, supported by authorities including The Savina and The Avance.
Regarding the Respondent’s Notice, the Court rejected arguments that Vessel B caused the crossing situation or that Vessel A was restricted in her ability to manoeuvre. The Court agreed with the trial judge that Vessel A was not restricted within the meaning of the Collision Regulations, as the pilot boarding had not commenced and Vessel A could have manoeuvred to keep clear.
On causative potency in apportionment, the Court reviewed extensive authority and confirmed that liability is apportioned based on both culpability and causative potency. Causative potency includes two aspects: contribution to the occurrence of the collision and contribution to the extent of damage. The Court accepted that Vessel B’s excessive speed increased the damage caused and was properly considered in apportionment. The Court rejected the argument that this amounted to double-counting, holding that the two aspects of causative potency are distinct and cumulative.
Overall, the Court upheld the trial judge’s approach and conclusions on all issues.
Holding and Implications
The Court DISMISSED the appeal in its entirety, affirming the trial judge’s decision.
The holding confirms that in situations where one vessel is navigating within a narrow channel and another is approaching it to enter, the crossing rules do not apply, to avoid conflicting navigational duties and to promote safety. Both vessels must be on sufficiently defined courses for crossing rules to engage. The Court also affirms that apportionment of liability properly considers both culpability and causative potency, including the contribution of faults to the extent of damage caused. No new precedent was established beyond the careful application and endorsement of existing principles and authorities. The direct effect is to maintain the apportionment of liability at 80% to the outbound vessel and 20% to the inbound vessel in this collision case.
