Conduct of Officers, Supercargo, Sailing Directions, Logbooks, and Cargo Ventilation Under a Time Charterparty

Conduct of Officers, Supercargo, Sailing Directions, Logbooks, and Cargo Ventilation Under a Time Charterparty

Clauses 9 to 12 of the New York Produce Exchange (NYPE) Charterparty Form deal with several practical matters that support the day-to-day operation of a ship under a time charterparty. These provisions concern complaints about the conduct of the master, officers, or engineers, the charterers’ right to appoint a supercargo, the giving of written voyage instructions and sailing directions, the keeping of accurate logbooks, and the master’s duty to use diligence in caring for cargo ventilation.

These clauses are usually less controversial than the larger employment, indemnity, hire, off-hire, or cargo-operation provisions of a time charterparty. Nevertheless, they are commercially important because they regulate how information, cooperation, supervision, and operational discipline are maintained while the ship is trading under the charterers’ employment orders.

Complaints About the Master, Officers, or Engineers in Time Charterparty

Clause 9 provides that if the time charterers have reason to be dissatisfied with the conduct of the Captain, Officers, or Engineers, the shipowners must investigate the complaint after receiving particulars and, if necessary, make a change in the appointments. The clause does not give charterers an unrestricted right to demand the removal of a member of the ship’s command or technical staff. It requires a reasoned complaint, followed by investigation by the shipowners.

The balance is commercially sensible. The master and crew remain appointed by the shipowners, and the shipowners remain responsible for the operation, navigation, discipline, and management of the ship. At the same time, the charterers are paying for the commercial use of the ship and are entitled to expect proper cooperation, competent performance, and reasonable attention to their lawful employment orders.

If a complaint concerns matters of employment, communication, cooperation, delay, conduct toward agents, or failure to give customary assistance, the shipowners should consider it seriously. If the complaint concerns navigation, safety, seaworthiness, or technical judgment, the shipowners must still investigate, but the master’s independent duty to protect the ship, cargo, and crew remains central.

Time Charterers’ Right to Appoint a Supercargo Under Time Charter

Clause 10 gives the time charterers permission to appoint a Supercargo to accompany the ship and observe that voyages are prosecuted with the required commercial efficiency. Under the traditional wording, the supercargo is to receive free accommodation and the same fare as the master’s table, with the charterers paying the agreed daily amount. The clause also deals with victualling pilots, customs officers, tally clerks, stevedore foremen, and similar persons when authorised by the charterers or their agents.

The right to appoint a supercargo is now less commonly exercised than it was in earlier trading practice. Modern communication, port reporting, electronic documentation, weather routing, cargo-survey systems, and agency networks have reduced the need for a charterers’ representative to travel physically with the ship. Even so, the clause remains relevant where the cargo, voyage, trading programme, or loading and discharge arrangements justify closer commercial oversight.

A supercargo is not part of the shipowners’ crew. The supercargo attends for the charterers’ benefit and is concerned mainly with the charterers’ commercial interests. That may include observing cargo operations, communicating with port agents, following voyage progress, helping to coordinate documents, and ensuring that the charterers’ instructions are understood and acted upon where appropriate.

The charterers are responsible toward the shipowners for the conduct of their supercargo. If the supercargo becomes involved in cargo operations or stowage decisions and negligent directions cause damage to the ship, cargo, or third parties, the resulting responsibility may fall on the charterers. The Imvros [1999] 1 Lloyd’s Rep. 848 is an example of the importance of a supercargo’s conduct in relation to stowage matters.

This point remains significant even where a charter has been amended by wording such as “and responsibility” in relation to the master’s supervision of cargo work. If the loss is in substance caused by a charterers’ representative giving negligent directions, the charterers may not avoid responsibility simply by pointing to the master’s general supervisory role.

Written Instructions and Sailing Directions Under Time Charter

Clause 11 requires the time charterers to furnish the master from time to time with all requisite instructions and sailing directions in writing. This wording is important because a time charterparty depends on the charterers’ ability to direct the commercial employment of the ship while the master retains responsibility for safe navigation and proper seamanship.

Written instructions reduce uncertainty. They assist the master, protect both parties from later disputes, and provide evidence of what was actually ordered. In a charterparty relationship where hire, off-hire, speed claims, deviation allegations, port calls, dangerous cargo information, routing decisions, and discharge arrangements may all have financial consequences, written orders can be decisive.

The charterers’ duty to provide requisite instructions may be especially important in dangerous cargo cases. If the charterers know, or ought to know, facts about the cargo that are necessary for the safe and proper prosecution of the voyage, those facts should be communicated clearly to the master. In that context, Clause 11 may support a shipowners’ claim where inadequate information or defective instructions contribute to loss, delay, danger, or liability.

The duty to provide sailing directions does not mean that the charterers may take over the master’s navigational judgment. The charterers may decide where the ship is to go and may give commercial routing instructions within the charter. However, the execution of the voyage remains subject to the master’s professional judgment on safety, weather, seaworthiness, crew protection, cargo care, and navigation.

Sailing Directions and the Boundary Between Employment and Navigation Under Time Charter

The distinction between employment and navigation is central to the operation of Clause 11. Employment concerns the commercial use of the ship: the ports, cargoes, general voyage programme, trading orders, and economic exploitation of the ship’s earning capacity. Navigation concerns seamanship: how the ship is safely handled, how weather and sea conditions are managed, and how the master executes the voyage at sea.

The leading modern discussion of routing and employment is found in The Hill Harmony [2001] 1 Lloyd’s Rep. 147. That decision recognised that general routing orders may fall within the charterers’ sphere of employment, particularly where the route affects the commercial performance of the voyage. However, such orders remain subject to the master’s overriding responsibility for safety and proper seamanship.

The practical result is that the master should not disregard the charterers’ routing instructions merely because he prefers a different route. At the same time, the master is not a passive messenger required to follow every routing suggestion regardless of weather, sea conditions, navigational risk, cargo safety, or the condition of the ship. A justified departure from directions may be defensible where safety or good seamanship requires it.

The U.S. Law Approach to Voyage Instructions Under Time Charter

Under U.S. maritime arbitration, the same practical tension appears between the charterers’ right to issue written voyage instructions and the master’s authority over navigation. In The Andros Mentor, SMA 2125 (Arb. at N.Y. 1985), the ship was chartered for a voyage from Vancouver to the Philippine Islands. The charterer instructed the master to follow a weather routing service, but the master instead used a more southerly route recommended by another service retained by the shipowner.

The alternative route added about 688 miles to the voyage. The charterer deducted hire for the additional time. The panel accepted that Clause 11 required the charterer to give written instructions and sailing directions, and that the master had an implied duty to follow them. However, the panel also emphasised that the master is not under an absolute duty to follow any weather routing advice. He remains the final judge of the best and safest course, having regard to the interests of both shipowner and charterer and to the safety of the ship, cargo, and crew.

The panel treated the master’s early statement that he would not follow the charterer’s routing advice as a technical breach of Clause 11. Nevertheless, on the evidence, the master was found justified in following the alternative course. The reasoning shows that a master’s refusal to follow directions will be assessed by reference to the facts, not by a rigid rule that every charterers’ instruction must be obeyed without judgment.

The same decision stated that the phrase “sailing directions” entitles a charterer to give general directions, such as instructions to proceed via the Panama Canal or via Cape Town, but does not normally permit interference with detailed navigation at sea. The master’s professional discretion remains important, and only a severely flawed or negligent exercise of that discretion will usually justify criticism or claim.

In The Agia Skepi, SMA 2891 (Arb. at N.Y. 1992), written voyage instructions also proved important. The charterer argued that oral instructions had altered the destination, but the charter required sailing instructions to be in writing. The panel gave greater weight to the written orders and allowed off-hire for time lost when the ship proceeded to the wrong port. The case illustrates the evidential value of written directions and the risk of relying on alleged oral changes where the charter demands written instructions.

Logbooks and Daily Log Copies Under Time Charter

Clause 11 also requires the master to keep a full and correct Log of the voyage or voyages. The log is to be open to the charterers or their agents, and the master must provide true daily copies when required, showing the ship’s course, distance run, and fuel consumption.

This obligation is not merely administrative. A logbook is often the principal evidence in disputes concerning speed and consumption, weather, routing, stoppages, engine performance, bunkers, delays, and the general prosecution of the voyage. A reliable log can support the shipowners’ position. A defective or unreliable log can seriously weaken it.

Speed and performance claims commonly depend on the weather actually encountered by the ship, the distance run, the time used, and the fuel consumed. Because weather and sea conditions cannot usually be reconstructed perfectly after the event, arbitrators often attach considerable importance to contemporaneous log entries, unless there is strong evidence that the entries are incomplete, inaccurate, or unreliable.

U.S. Arbitration Treatment of Logbook Evidence Under Time Charter

U.S. arbitration decisions show how important accurate logbooks can be. In The Largo, SMA 1230 (Arb. at N.Y. 1978), the charterer brought a speed claim. The disponent shipowner relied on the logbook to show unfavourable winds, seas, and fog. The panel found the log insufficiently complete to evaluate performance. It rejected the disponent shipowner’s argument that it had no control over the registered shipowner’s personnel and therefore no responsibility for the defective logs.

The panel held that the charterparty clearly required the master to keep a full and correct log and to provide true copies when required. A disponent shipowner who charters a ship onward must therefore take practical steps to obtain and provide accurate log records. It cannot avoid the contractual consequence by saying that the physical log was kept by the registered shipowner’s crew.

In The Punica, SMA 3513 (Arb. at N.Y. 1999), the panel majority placed considerable weight on log entries showing moderate rolling and rejected the charterer’s expert argument that the ship must have been rolling violently. By contrast, in The Bertina, SMA 3144 (Arb. at N.Y. 1995), the panel treated the logbooks as completely discredited after serious irregularities, including extensive erased or altered entries, were alleged. The panel drew adverse inferences from the poor logkeeping and found serious unseaworthiness and negligence, although the fraud allegation failed for lack of evidence.

Other cases show the same pattern. In The Golden Shimizu, SMA 2991 (Arb. at N.Y. 1993), the panel rejected the charterer’s attack on the logs and accepted the general proposition that the master’s logs are normally reliable evidence of weather unless impugned by positive evidence of obvious or wilful inaccuracies. In The Konkar Kinos, SMA 2631 (Arb. at N.Y. 1990), the panel accepted the ship’s logs and abstracts for weather and speed, although it found insufficient data to calculate fuel consumption and carried out its own assessment.

In The United Bounty, SMA 2040 (Arb. at N.Y. 1984), the panel compared the ship’s logs with a weather routing service’s analysis. Although arbitrators usually treat the master and officers as the best observers of actual conditions at sea, the panel found the log entries unreliable because the reported weather pattern appeared highly unusual. It relied instead on the weather routing analysis. In The Mangalia, SMA 2839 (Arb. at N.Y. 1991), discrepancies and omissions in the log led the arbitrator to rely on an independent company’s weather reports.

These decisions show that logbooks are not automatically conclusive. They are powerful evidence when prepared properly, contemporaneously, and consistently. They become vulnerable when they are incomplete, altered, formulaic, contradicted by independent evidence, or lacking in the data needed to assess the claim.

Statutory Logbook Requirements Under U.S. Law

U.S. law also contains statutory requirements for logbooks on United States flag ships. Under 46 U.S.C. §§ 11301–11303, certain entries must be made as soon as possible after the relevant occurrence and must be signed. Violation of those requirements can give rise to a civil penalty. Although those statutory provisions concern U.S. flag ships, they reinforce the broader maritime principle that a ship’s log should be contemporaneous, accurate, and reliable.

Ventilation of Cargo Under Time Charter

Clause 12 provides that the master shall use diligence in caring for the ventilation of the cargo. This is a short clause, but it can have practical significance where cargo is sensitive to moisture, sweat, heating, odour, condensation, ventilation pattern, temperature variation, or atmospheric condition inside the cargo spaces.

The clause does not impose an absolute guarantee that cargo will remain free from damage. Its language is one of diligence. The master must take reasonable and seamanlike care in relation to ventilation, having regard to the nature of the cargo, voyage conditions, weather, route, sea temperature, air temperature, hatch and ventilator arrangements, and any relevant cargo instructions.

Ventilation decisions may involve difficult judgment. Ventilating at the wrong time may introduce moist air and increase condensation risk; failing to ventilate when appropriate may allow heat, odour, or moisture to accumulate. The master must therefore consider the cargo and conditions rather than treating ventilation as a routine mechanical exercise.

Where cargo damage is alleged to have resulted from ventilation, the logbook and contemporaneous records will often be important. Records of weather, sea temperature, air temperature, hold condition, ventilation openings, hatch closures, rainfall, sea spray, and any cargo-care instructions may help determine whether the master used the required diligence.

Commercial Importance of Clauses 9 to 12 in Time Charterparty

Although Clauses 9 to 12 are relatively concise, they support several essential features of a time charterparty. They protect the charterers’ interest in competent conduct and commercial cooperation, preserve the charterers’ ability to appoint a supercargo where needed, require written instructions and sailing directions, secure access to reliable voyage records, and impose a duty of diligence in cargo ventilation.

In practical operation, these clauses work alongside the broader employment clause. The charterers may direct the ship’s commercial employment, but the master remains responsible for safe navigation, proper seamanship, cargo care, and reliable recording of the voyage. When disputes arise, the outcome often turns on whether instructions were properly given, whether the master’s response was reasonable, whether log records are trustworthy, and whether cargo-care duties were performed with diligence.

For shipowners, the lesson is to investigate conduct complaints properly, maintain clear operational records, insist on written instructions where the charter requires them, and ensure that logbooks and cargo-care records are accurate. For time charterers, the lesson is to issue clear written orders, provide all necessary information, understand the limits of routing instructions, and recognise that a supercargo or agent acting on their behalf may create responsibility if negligent directions cause loss.

The clauses are therefore not minor administrative wording. They are part of the operational framework that allows a time charterparty to function: charterers direct the commercial use of the ship, shipowners maintain command and safety responsibility, and both sides rely on written instructions and accurate records to manage the legal and commercial consequences of the voyage.
