What 1 World Yacht Sales does

Yacht Sales International (YSI), operating under the brand 1 World Yacht Sales, is a privately held luxury yacht brokerage and advisory firm founded in 2014 in Fort Lauderdale, Florida by Udo Willersinn and Wendy Meade Willersinn. The firm operates across five U.S. office locations—Fort Lauderdale (headquarters), Palm Beach, Cape Coral, Annapolis, and Chicago—and employs 17 expert brokers who deliver private yacht advisory, brokerage services, and hybrid/electric yacht consulting to high-net-worth buyers and sellers. YSI is an authorized Greenline Yachts dealer (relationship maintained since founding) and, as of July 2026, the exclusive U.S. and Caribbean dealer for Revolution Marine Group, giving it territory rights to the S60 and S60e new-yacht lineup. The firm's listing inventory includes 7,421+ yachts, with 15+ hybrid models surfaced as a specialty, and it supplements brokerage with hybrid/electric refit and conversion consulting targeted at Great Loop cruisers and eco-conscious HNW buyers.

The core "platform" is a relationship-driven brokerage stack rather than a technology product: a curated catalog of used listings, off-market opportunities accessible through broker relationships, and a content layer comprising a YouTube channel with 19,600+ subscribers and the YSI Journal. There is no disclosed proprietary technology stack, no AI/ML components, and no consumer-facing software product; the firm's intellectual property lies in broker expertise, OEM dealer authorizations, and brand authority within the hybrid/electric yacht niche.

YSI generates revenue through three streams: commissions on used yacht sales (transaction-fee based, individualized and not publicly disclosed), dealer margins on new yacht sales for Greenline and Revolution Marine Group models, and private yacht advisory and consulting fees for hybrid/electric buyers. Go-to-market is primarily enterprise field sales through private consultations, augmented by exclusive OEM channel partnerships and content marketing. The firm is privately held with no public financial disclosures, no announced funding rounds, no acquisitions, and no IPO activity.
