Fantasea Connections runs adults-only lifestyle cruises: clothing-optional sailings for couples and single women, held aboard mainstream cruise ships. The organiser describes workshops and playshops, meet and greets, themed nights and pool parties, with a kink playroom on board — the House of Black, with a St Andrew's cross, spanking bench and sensory bench, and staff who run demonstrations and pre-booked scenes.

Single men cannot book. The organiser says it reserves the right to refuse boarding to people who booked as a couple but do not meet that requirement, to keep what it calls a truly uninhibited clothing-optional experience.
