Safe Port

What it does

A safe port warranty is the charterer's undertaking that any port to which it orders the vessel will be safe for that particular ship at the relevant time. The classic formulation is that the ship must be able to reach the port, use it, and leave it without being exposed, in the absence of some abnormal occurrence, to danger that cannot be avoided by good navigation and seamanship. It covers physical hazards and political ones alike.

The warranty bites when the charterer exercises its right to nominate or order a port under the charter. If the nominated port is unsafe in the relevant sense and the ship suffers loss or delay as a result, the charterer is in breach. The promise is judged against the specific vessel and the conditions prevailing when she is there, not against ports in the abstract, which is what makes its application so fact-sensitive.

Commercial effect

The safe port warranty allocates to the charterer the risk that the place it sends the ship turns out to be dangerous, whether through inadequate depth, exposure to weather, poor layout, or political hazard. Because the charterer controls the choice of port, the warranty puts the consequences of a bad choice on the party best placed to assess and avoid it, and it can found a substantial damages claim if the ship is harmed.

For the owner the warranty is an important protection, since the master must generally follow the charterer's lawful orders as to ports. Without the promise, the owner would bear the loss from a port it did not choose. The scope of the warranty, and whether it is given as an absolute promise or only a duty of due diligence, is therefore a meaningful point in the bargain.

Owner's perspective

The owner wants a clear, preferably absolute, safe port warranty so that if the charterer sends the ship to a dangerous port and she is damaged or delayed, the charterer answers for the loss. The owner relies on it because the master is bound to obey legitimate trading orders, so the choice of port, and its risks, are effectively out of the owner's hands once the charter is fixed.

The owner resists attempts to dilute the promise into a mere duty of due diligence in selecting the port, because that shifts the risk back toward the owner where the danger was not reasonably foreseeable. The owner also wants the warranty to extend to safe access and departure, not just the port in isolation, so that approach channels and berths are covered as well.

Charterer's perspective

The charterer wants the warranty confined as far as possible, for instance to a duty of due diligence rather than an absolute guarantee, so that it is not strictly liable for hazards it could not reasonably have known about. It is wary of an absolute promise because it can be held responsible even for dangers that materialise unexpectedly at a port that was, on reasonable assessment, safe when nominated.

The charterer also watches the master's residual duty: even with a safe port warranty, the master can decline to enter a port that is obviously dangerous, and doing so does not necessarily relieve the charterer. The charterer therefore tries to align the warranty with realistic trading patterns and to exclude abnormal occurrences that no amount of care could have foreseen or prevented.

Negotiation points

• Whether the warranty is an absolute promise of safety or only a duty of due diligence in nominating the port.
• Whether it extends to safe access and departure (approaches, channels) as well as the port itself.
• How abnormal occurrences, outside the charterer's reasonable contemplation, are treated.
• The interaction with the master's right to refuse an obviously unsafe port.

Common variations

• An absolute safe port warranty covering reaching, using, and leaving the port.
• A due-diligence formulation, promising care in nominating a safe port rather than guaranteeing safety.
• A named-port fixture where safety of the agreed port is treated differently from a charterer's free choice.
• A warranty expressly extended to safe berth and safe anchorage as well as the port.
