While a time charter is, as the name implies, a contract for the definite period of time expressed in the charter, it is obvious that the exigencies of navigation frequently render it impossible to redeliver the vessel on the precise date when the period expires. It is customary, therefore, to provide that the charter hire shall continue at the same rate until the time of redelivery unless the vessel be lost. It is the duty of the charterer to redeliver the vessel as nearly as possible to the expiration date of the charter, but if the vessel is delayed through no fault of his, he cannot be held in damages for breach of the charter, even though he may not be able to make redelivery for months beyond the expiration date. So long as the delay be practically unavoidable, he is liable merely for the stipulated charter hire until redelivery, and not in damages for breach of the charter (Anderson v. Munson, 104 Fed. 913).

The word "about" as a qualification of the charter period is sometimes inserted in time charters, as a further protection to the charterer, but it does not diminish his obligation to surrender the vessel as nearly as possible to the expiration date.

(d) Cancellation and Withdrawal.

Charters usually contain a clause which provides that, if the vessel fails to arrive at the loading port by a certain date, in condition to be laden—i.e., with cargo space available—the charterers may cancel the obligation. The clause does not entitle the vessel to loaf toward the loading port so as just to arrive by the cancellation date. If she does not proceed with reasonable promptness, the charterer will be entitled to damages, even though she arrive by the cancellation date.

Correlative to the charterer's right of cancellation, it is usual for charter parties to contain a provision to the effect that charter hire is to be paid in advance and that in default of such payment the owner shall be entitled to withdraw the vessel from the charterer.

(e) The Breakdown Clause.

Time charters frequently provide that in the event of loss of time arising from the breakdown of machinery, lack of men or supplies for more than twenty-four hours, the payment of charter hire shall be suspended for the period from which she is inoperative, but if the vessel is driven into port by circumstances of weather or accident to cargo, the loss of time due to these causes shall fall upon the charterer. Such provisions are enforcible according to their language and intent. If the breakdown endures beyond the period of twenty-four hours the charter hire ceases not only for the excess, but for the twenty-four hours also.

19. Lien for Freight and Charter Hire.—

It is fundamental that the goods carried are liable for the carrying charges, but the questions arise: In whose favor does the liability exist, and during what period does it exist? The lien for freight exists in favor of the person with whom the shipper contracts to carry the goods. Where the shipowner is operating the vessel on his own account as a carrier, the lien for freight exists in his favor. Where the vessel is chartered the contract of carriage is between the shipper and the charterer, and the lien for freight exists in favor of the charterer. The owner of a chartered ship has no lien for freight (unless conferred by the cesser clause, mentioned below), but he may have a lien on the goods to the extent of the unpaid freight for the purpose of securing his charter hire. This lien does not exist in favor of an owner who has demised or let the ship to the charterer, unless there is an express stipulation to that effect.

The so-called "cesser clause" is to the effect that "owner to have lien on cargo for freight, dead-freight, and demurrage, charterer's liability to cease when cargo shipped." The purpose of this clause is to bring the charterer's liability to an end at the loading port. In return for his exemption from liability to suit at the port of destination, he turns over to the shipowner his lien on the cargo for freight, dead-freight and demurrage.
