Named after St. Regis founder John Jacob Astor’s 1910 yacht of the same name, Norma has four luxurious cabins catering to six guests, who can look forward to all the luxuries expected of a St. Regis stay, including private butler, full meal service and daily sunset champagne sabering ritual.

The Azimut flybridge 66 yacht can be chartered for daytime diving excursions or sunset cruises, but for the full experience, book an overnight cruise and wake up to the gentle lapping of Indian Ocean waves at the bow, for a mere $25,000 per night.
