In any negotiation, the person who controls the vessel and charters her out to charterers is the owner for the purposes of that Charter Party. The person who controls the cargo and charters in a vessel is the charterer. The maintenance of the vessel and payment of the crew remain the responsibility of the Head Owner under both voyage and time charters, regardless of the number of times the vessel is subsequently re-let in a chain. In other words, if a grain house charters a vessel and then re-lets her, that grain house will become the nominal (Disponent) owner for the re-letting (i.e. the second Charter Party), even though their basic trade is as a Grain House.
