A By-The-Cabin Yacht Charter, also known as a cabin charter or a shared yacht charter, is a type of yacht rental where you can book a cabin or stateroom on a yacht already chartered by someone else. With a by-the-cabin yacht charter, you share the yacht with other passengers and have access to the common areas of the yacht, such as the dining room, lounge, and deck.

By-the-cabin yacht charters can be more affordable than booking a private yacht charter, as you only pay for your own cabin rather than the entire yacht. They can also be a good option for solo travellers or small groups who want to experience a yacht vacation but don't want to pay for an entire yacht.

By-the-cabin yacht charters may be crewed (meaning a professional crew is provided to operate the yacht and attend to your needs) or bareboat (meaning you are responsible for operating the yacht yourself). The amenities and services will depend on the yacht and the charter company.

It's always a good idea to carefully review the terms and conditions of a by-the-cabin yacht charter before booking to understand what is included and what is not.
