Sail to the tiny island of Petit Nevis for lunch and more beach time. On to Mustique, the island of royals, the rich and the famous, you can overnight in Britannia Bay. A spine of hills 400 to 600 feet in elevation runs down the midsection of Mustique, providing sweeping views of the sea that make an ideal setting for the palatial estates, about 90 in all, dotting the lush, green slopes extending to the edges of pristine white-sand beaches. Celebrities, business magnates, and royalty have made the island a cherished retreat. Mustique yachting ushers you into this exclusive world.
