Factual and Procedural Background
On 2 August 2000, two vessels, herein referred to as Vessel A and Vessel B, collided in a river channel near a port in Venezuela. Vessel A, a large cargo ship registered in London and laden with steel products, was undertaking a 180-degree starboard turn to begin its downriver passage, assisted by two tugs and a local pilot. Vessel B, a smaller cargo ship registered in Limassol, was anchored nearby, yawing and swaying under the influence of a strong river current. The collision occurred between the bow of Vessel B and the port side of Vessel A, causing Vessel A to sink rapidly but without loss of life or significant injury.
The case involved disputes over Vessel B's anchorage position, its control of yaw and sway, and the manner in which Vessel A executed its unberthing manoeuvre. The parties presented extensive factual and expert evidence, including simulations of vessel tracks and collision positions. The court also considered prior related proceedings and the procedural framework for expert advice under the Human Rights Act.
Legal Issues Presented
- Was Vessel B's anchorage position unsafe?
- Was Vessel B at fault for failing to control its yawing and swaying while at anchor?
- Was Vessel A at fault in terms of lookout and appreciation prior to and during its manoeuvre?
- Was Vessel A at fault in the planning and execution of its unberthing manoeuvre?
- Was Vessel A at fault in its manoeuvres after becoming aware of the proximity of Vessel B?
- What was the causative fault or faults leading to the collision?
- How should liability be apportioned between the vessels?
Arguments of the Parties
Appellant's Arguments (Vessel A)
- Vessel B was solely or predominantly to blame due to anchoring in an unsafe position in a narrow channel close to busy berths.
- Vessel B failed to take adequate steps to control yaw, sway, and dragging, despite pronounced movement caused by current and anchorage conditions.
- Vessel A maintained a proper lookout and conducted its manoeuvre reasonably; the collision was caused mainly by Vessel B's intermittent movement into the channel.
- The "last opportunity rule" should not apply to shift blame onto Vessel A as the moving vessel.
Appellee's Arguments (Vessel B)
- Vessel A was solely or predominantly to blame for the collision.
- Vessel B’s anchorage was safe and its yawing was normal for a vessel at anchor in a strong current; any dragging was minimal and immaterial.
- Vessel B took reasonable measures to control yaw, including attempts at an open moor and use of helm; use of engines to control yaw was not reasonably expected.
- Vessel A failed to plan or appreciate the risks adequately, did not maintain a proper lookout, and used excessive engine power during the turn, causing the vessel to proceed too far north and downstream.
- Even if Vessel B had failed in some respects, the collision would have occurred regardless due to Vessel A’s errors.
- Vessel B’s poor record keeping and log alterations should not result in causative blame but may warrant judicial disapproval.

Court's Reasoning and Analysis
The court conducted a detailed and methodical analysis of the facts and legal principles, guided by expert evidence and established precedents. It began by examining the anchorage position of Vessel B, concluding that while it was anchored in the channel’s northern side, this position was not unsafe in itself given local practice and absence of objections from port authorities or pilots.
Next, the court addressed the duty of an anchored vessel to control yaw and sway. It found that Vessel B did owe such a duty, grounded in good seamanship and supported by case law. Vessel B failed to anchor to an open moor and did not effectively use helm to control yaw, representing breaches of this duty. However, the court accepted that the use of engines to control yaw was not reasonably required.
The court then turned to Vessel A’s conduct, finding significant failures in lookout and appreciation. Despite good weather and visibility, Vessel A’s master and pilot failed to accurately assess the positions and behaviour of anchored vessels, including Vessel B’s pronounced yawing. The court emphasized the requirements of Rules 5 and 7 of the Collision Regulations 1972, which mandate maintaining a proper lookout by all available means and assuming risk of collision where doubt exists.
Vessel A’s unberthing manoeuvre was inadequately planned and executed. The use of sustained half and full ahead engine power during the turn caused the vessel to move too far north and downstream, reducing the effectiveness of tug assistance and increasing collision risk. The court relied on advice from nautical assessors to confirm these findings.
Regarding the actions after Vessel A became aware of Vessel B’s proximity, the court found that the master’s instinctive order to stop engines was understandable and not causative of the collision, which by then was likely unavoidable due to earlier faults.
On causation, the court applied established principles that causative fault must form a link in the chain leading to collision. It found Vessel A’s faults to be major contributory causes and that Vessel B’s failure to control yaw, while a fault, was not causative as the collision would likely have occurred regardless. The court rejected the "last opportunity" rule as obsolete.
In summary, the court concluded that the collision was primarily caused by Vessel A’s failure to keep clear of a visible anchored vessel and poor seamanship in manoeuvring, despite Vessel B’s shortcomings in controlling yaw.
Holding and Implications
Vessel A is held solely liable for the collision.
The court ruled that Vessel B’s anchorage position was not unsafe, and although Vessel B was at fault for failing to control yaw and sway adequately, this fault was not causative of the collision. Vessel A’s failures in lookout, appreciation, and manoeuvring were the major and causative factors. Consequently, no apportionment of liability arises, and the case does not establish new legal precedent beyond reaffirming existing principles on causation and duty of care in maritime collisions.
