Charter Party

A charter party is the contract between a shipowner and a charterer by which the shipowner provides a vessel — or the whole or part of its capacity — for the carriage of cargo, in return for the payment of freight or hire. There are three main forms: voyage charter, time charter, and bareboat (demise) charter. In a voyage charter, the shipowner provides the ship and crew to carry a specified cargo from one port to another for a freight rate. In a time charter, the charterer directs the vessel's employment for a defined period, paying hire, whilst the shipowner manages the crew and maintenance. In a bareboat charter, the charterer operates the vessel as if it were the owner. For a master, the charter party defines the operational parameters within which the vessel must be traded: the agreed speed and consumption, the cargo exclusions, the port rotation, laytime provisions, and demurrage terms. The master must be aware of the charter party terms because decisions made on board — such as accepting a berth, signing bills of lading, or delaying departure — have direct financial consequences for the shipowner or charterer. The charter party also defines the division of responsibilities between owner and charterer under various standard forms — GENCON, NYPE, Baltime — and any addenda or riders. Officers must understand the vessel's obligations under the applicable form and communicate any facts that could affect freight, demurrage, or cargo liability promptly to the owner and charterer through the master's log and formal notices.
