Sara Ryan Duffy

Special booking: In 2010, Duffy planned a vacation to the Mediterranean that included a cruise on a 300-foot yacht stocked with 10 pounds of caviar. Insider clout: For clients attending the Cannes Film Festival in May, Duffy chartered the Deja Too—a yacht that calls in France, Italy, and Sardinia. Besides its formidably opulent design (think Empire goes sailing) and vast aft terrace space, the Deja Too’s four equal-size suite cabins can be converted into two VIP suites, or one master suite and two standard cabins. Years as agent: 18. Other specialties: Yachts, villas, private jets, celebrity travel. Consulting fee: Varies.
