Why YSI

Representation Matters

Depth of Knowledge

We understand propulsion systems, ownership economics, survey nuance, and market timing. Our guidance goes considerably further than the listing.

Access

Exclusive listings, off-market opportunities, and a network built over a decade in the industry. Many of our finest transactions begin with a private conversation.

Commitment

Udo Willersinn is personally involved in every listing. One of our experienced brokers will be your primary agent — people who know the market, know the product, and are accountable to your outcome.

Hybrid & Electric

The New Standard in Yacht Ownership

Hybrid yachts have fundamentally changed what ownership feels like. Quieter anchorages. Lower fuel consumption. Reduced generator dependence. A more refined onboard experience — not as a trade-off, but as the baseline.

Yacht Sales International has been at the forefront of hybrid and electric yachting since our founding. We understand these systems technically, not just commercially. That matters when you're making a significant purchasing decision.

  • Silent anchoring — no generator hum at sunset
  • Meaningful reduction in fuel consumption
  • Fewer engine hours and lower maintenance exposure
  • Modern energy management as standard
  • Strong and growing resale demand

Authorized Dealer

Greenline Yachts

Greenline has become the benchmark in hybrid motor yacht design — combining award-winning propulsion technology, exceptional natural light, and owner-friendly layouts that perform as well in the Bahamas as they do on the Great Loop. As an authorized Greenline dealer, YSI offers the full ownership experience: model consultation, sea trials from Fort Lauderdale, and support that extends well past delivery.

Our Story

Built on Relationships,
Not Transactions

Yacht Sales International was founded by Udo Willersinn and Wendy Meade Willersinn — whose combined background spans European marina operations, technical systems expertise, and over a decade of hands-on brokerage experience across U.S. markets.

Clients return to YSI because the guidance continues long after closing. That's not a marketing statement — it's how we've built every relationship in this business.
