What is Bareboat Charter?

Legal Definition
A bareboat charter or demise charter is an arrangement for the chartering or hiring of a ship or boat, whereby no crew or provisions are included as part of the agreement; instead, the people who rent the vessel from the owner are responsible for taking care of such things.

There are legal differences between a bareboat charter and other types of charter arrangements, commonly called time or voyage charters. In a voyage or time charter, the charterer charters the ship (or part of it) for a particular voyage or for a set period of time. In these charters the charterer can direct where the ship will go but the owner of the ship retains possession of the ship through its employment of the master and crew. In a bare-boat or demise charter, on the other hand, the owner gives possession of the ship to the charterer and the charterer hires its own master and crew. The bare-boat charterer is sometimes called a "disponent owner". The giving up of possession of the ship by the owner is the defining characteristic of a bareboat or demise charter.
