Meet Our Team
John Prather
Co-Founder and Head of Brokerage
John Prather is a Maryland native and co-founder of Delmarva Marine Group, specializing in yacht and boat sales with a deep, hands-on understanding of how boats are built, used, and valued. His lifelong involvement in boating—combined with more than 20 years of professional experience on the water—gives clients a practical advantage when buying or selling.
John has spent his career operating, evaluating, and working aboard a wide range of vessels throughout the East Coast and internationally, including the Bahamas, Mexico, Costa Rica, and the Dominican Republic. This experience allows him to accurately assess boat performance, layout, construction quality, and real-world functionality—key factors in pricing, marketing, and matching buyers with the right vessel.
Beyond brokerage, John has been directly involved in the full build process of multiple boats, from 20-foot outboards to some of the largest sportfishing yachts on the market. His in-depth knowledge of boat construction, systems, and manufacturer standards—along with strong relationships within the industry—provides clients with informed guidance throughout every stage of a transaction.
An accredited yacht broker, John is known for his integrity, transparency, and detail-driven approach. He works closely with each client to ensure their boat is properly represented, strategically marketed, and sold with their best interests as the top priority.
Jon Duffie
Jon has held a U.S. Coast Guard Captain’s License for over 20 years and has spent the past two decades competing in fishing tournaments and operating boats throughout the East Coast, the islands, and beyond. His extensive travel by boat—including journeys through the islands and the Panama Canal—and fishing experience across numerous countries in Central America have given him a deep, real-world understanding of vessel performance, reliability, and offshore capability.
Fishing and boating have always been at the core of Jon’s career, naturally leading him into boat building and customization. As the owner of Duffie Boatworks, he has been directly involved in the construction, refit, and sale of multiple vessels, providing him with valuable insight into hull design, systems integration, and build quality—knowledge that directly benefits clients navigating the buying or selling process.
As co-founder of Delmarva Marine Group, Jon’s combined experience on the water and in the boat-building industry played a key role in shaping the company’s hands-on, client-focused approach to brokerage.
