Question 1

You receive a MAYDAY from a vessel 80nm away. You are the nearest vessel. Your passage would be significantly delayed and the charter party has no force majeure clause for SAR. You have medical personnel needed urgently at your destination. Describe your decision.

Accepted Answer

The duty to render assistance under SOLAS V Regulation 33 and UNCLOS Article 98 is an absolute legal obligation — it cannot be overridden by commercial considerations or charter party terms. "The master of a ship at sea which is in a position to be able to provide assistance, on receiving a signal from any source that persons are in distress at sea, is bound to proceed with all speed to their assistance." Procedure: (1) Proceed at full speed to the distress position; (2) Acknowledge the MAYDAY on VHF Ch 16 and notify the MRCC; (3) Inform the company — they should notify the charterer and invoke the force majeure/marine peril provisions; (4) Releasing conditions (SOLAS V/33(2)): you may be released from the duty only when the master of the vessel in distress or the SAR authority or another vessel reaches those in distress and informs you your assistance is no longer needed. Until released, you must proceed. The medical personnel situation: this is a competing obligation but does not override SOLAS V/33. The company should alert the receiving facility to the delay. The duty to render assistance is one of the oldest and most fundamental obligations in maritime law. SOLAS V/33 and UNCLOS Art 98 both create this duty. There is no commercial exemption. There is no "someone else can do it" exemption if you are the nearest vessel. The releasing conditions are specifically set out: you are released ONLY when: (a) the persons in distress have been taken aboard another vessel; (b) the master of the distressed vessel informs you that assistance is no longer required; (c) the MRCC releases you. Until one of these conditions is met, you must continue. Case law: masters have been prosecuted for failing to render assistance. The Merchant Shipping Act 1995 s.93 creates a criminal offence for a master who, "upon receiving at sea a signal of distress or information from any source that a vessel or aircraft is in distress, fails, without reasonable cause, to proceed with all speed to the assistance of the persons in distress." The "reasonable cause" exception is narrow — it means the rescue attempt would put your own vessel or crew in serious danger (e.g., rescue in hurricane conditions might genuinely be unsafe). Charter party delays are NOT reasonable cause.

Question 2

Your charterer is demanding you maintain 16 knots to arrive on schedule. Visibility has dropped to 0.5nm in fog. Your safe speed assessment suggests 6 knots maximum in these conditions. The charterer threatens to claim laytime damages. What is your position under COLREGs and ISM?

Accepted Answer

COLREGs Rule 6 (Safe Speed) and ISM Regulation 5 (Master's Overriding Authority) together create an absolute obligation: the Master must navigate at safe speed regardless of commercial pressure. A speed that allows the vessel to stop within half the visibility distance or less is the practical test in restricted visibility. At 0.5nm visibility with significant traffic risk, 6 knots or less is likely necessary. ISM Code Reg 5: "The Company shall establish in the SMS that the Master has the overriding authority and the responsibility to make decisions with respect to safety and pollution prevention and to request the Company's assistance as may be necessary." The charterer's laytime claim cannot override the Master's safety obligation. Action: reduce to safe speed; document the decision in the OLB with the meteorological conditions and COLREGs reasoning; inform the company in writing; request the company provide written confirmation if they want you to maintain speed (they will not do so as it would make them complicit). A collision caused by excessive speed in fog would expose the Master personally to criminal prosecution under the Merchant Shipping Act 1995. Commercial pressure versus safety is the paradigm Master-level examination question. The legal position is unambiguous: COLREGs are statutory regulations, not guidelines. Rule 6 imposes a legal duty on the Master — it is not a discretionary standard. A breach of Rule 6 that results in a collision constitutes a criminal offence under the Merchant Shipping Act 1995 Section 58 (misconduct endangering ship or persons on board) and potentially Section 131 (oil pollution). The Master is personally exposed — not just the company. Laytime and commercial damages: a time charterer's laytime claim arising from weather-related slow steaming is a commercial dispute handled through the P&I Club and the voyage charter provisions. A successful laytime claim costs money; a conviction for causing a collision through excessive speed costs the Master their certificate and potentially their freedom. The ISM system specifically creates the "overriding authority" provision to give Masters a clear documented basis for resisting commercial pressure — the OLB entry and company communication create a contemporaneous record.

Question 3

Your vessel collides with another vessel in a TSS. Two crew members on the other vessel are injured. Investigations show your OOW was on the correct side of the TSS but failed to take avoiding action in time. As Master, what is your criminal liability exposure?

Accepted Answer

Criminal liability exposure for the Master: (1) Merchant Shipping Act 1995 Section 58 — Conduct endangering ship or persons on board: "A master of, or seaman employed in, a United Kingdom ship who, while on board the ship, does any act which causes or is likely to cause the loss or destruction of or serious damage to his ship or the death of or serious injury to a person on board his ship is guilty of an offence." This applies where the Master failed in their supervisory duty; (2) MS Act 1995 Section 100 (manslaughter) and Gross Negligence Manslaughter (common law) — if injury leads to death, the Master may face manslaughter charges if their conduct was grossly negligent; (3) ISM duty: failure to ensure adequate bridge watchkeeping and OOW supervision; (4) The Master is also exposed to personal P&I subrogation claims if found personally negligent. The fact that the OOW was technically compliant with lane navigation but not with COLREGs Rule 8 timing raises questions about bridge supervision and watchkeeping instruction under the Master's standing orders. Masters are regularly prosecuted following collisions — this is not theoretical. The MS Act 1995 creates specific criminal offences for masters and seafarers. Section 58 covers "conduct endangering" — it does not require injury; the potential to cause injury is sufficient. For serious injuries or deaths, the Crown Prosecution Service (CPS) will consider gross negligence manslaughter charges. The Master's supervisory responsibility: even when not on the bridge, the Master is responsible for ensuring the watchkeeping system is fit for purpose — standing orders must specify safe speed, calling the master procedures, and COLREGs compliance requirements. If standing orders were inadequate and the OOW failed to follow safe practices, the Master bears some responsibility. Case law: Captains of numerous vessels have been prosecuted under MS Act provisions following collisions in UK waters — including the incidents in the Thames Estuary and Solent area. The MAIB investigation report following a collision will normally address criminal liability questions separately from the safety investigation.
