Our Story

A Different Kind of Yacht Brokerage

Yacht Sales International was founded on a simple premise: buying or selling a yacht should be a clear, informed, and rewarding experience — not an opaque one. We built our business around transparency, deep product knowledge, and a genuine passion for the water.

Today, YSI operates five offices across the eastern United States, representing both brokerage listings and exclusive new yacht brands including Greenline, Fjord, RYCK, Sialia, and Alva Yachts. We are one of the few brokerages with a dedicated focus on hybrid and electric propulsion, reflecting our belief that the future of yachting is as exciting as it is sustainable.

Whether you're buying your first yacht or your fifth, selling a vessel you've loved, or evaluating the latest in hybrid technology — our team brings the same commitment: expert guidance, honest counsel, and real time on the water.

  • Full transparency on pricing and process
  • Sea trial-driven approach to every purchase
  • In-house video & digital marketing on every listing
