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

There are legal differences between a bareboat charter and other types of charter arrangement, such as crewed or luxury yacht charter, 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 bare-boat or demise charter.

There are also hundreds of bareboat yacht charter brokers or agent companies. These companies offer yacht finding and travel organisation services similar to travel agent only more specialised. Their purpose is to use their experience and networks to locate a client's ideal bareboat in terms of price and location.

Bareboat hire has become increasingly common since the mid-1990s and in particular since the early 2000s. There has been increasing demand for yacht vacations and many experienced and semi-experienced ‘yachties’ now consider it easier and cheaper to hire a bareboat, rather than own their own yacht. While both the international leisure travel industry (particularly outdoor activities based vacations) and the boating industry has both boomed in the last decade, so too has the bareboat charter industry which incorporates both of these pursuits.
