In article 184, § I of the Maritime Code ( article 188 § 1 of the New Maritime Code), Polish law defines time charter as a contract by which the ship-owner agrees, for remuneration, to hand over to the control of the chartering party a vessel with its crew for a defined period of time or for the duration of one or several successive voyages for purposes defined by the contract. The chartering party has the right only to give the captain instructions in the matter of the exploitation of the ship and within limits set out in the charter contract. The scope within which the crew is under the command of the charterer can be fixed by the parties to the contract. Almost all authors of handbooks on maritime law and of studies of chartering are agreed that the temporary charterer of a vessel does not have any right to interfere in navigational matters.
