Broker Overview
The 2026 Diamond Yachts EF66 represents a compelling opportunity in the power catamaran market. As a new, built-to-order vessel, it offers a discerning buyer the unique advantage of defining the final specifications and outfitting to their precise requirements. This 66-foot catamaran is designed for expansive living and entertaining, characterized by its clean lines and innovative spatial design, particularly evident in the multi-zone flybridge and generous deck areas. Propulsion is handled by twin Cummins QSB6.7 HP engines, a reliable and efficient choice for a vessel of this size. While specific performance data will depend on the final build, this setup is well-suited for comfortable cruising. The fiberglass hull ensures a robust and durable platform. For a buyer seeking a modern, spacious, and customizable power catamaran without the compromises of a pre-owned vessel, the EF66 stands out as a strong contender. Its 'new' condition and 'built to order' status mean you are investing in a yacht tailored to your exact needs from day one, avoiding the typical refit costs associated with brokerage boats.

Expert Review
The Diamond Yachts EF66 enters the market as a purpose-built power catamaran focused on luxury, space, and customization. The build quality, while new, is expected to meet modern catamaran standards, emphasizing robust fiberglass construction. Sea-keeping characteristics for a 66-foot power cat are generally stable and comfortable, particularly in a head sea, thanks to the twin-hull design. Value for money is strong given its 'new' status and the ability to tailor the build; you're getting a bespoke yacht without the typical custom build premium. During a survey, focus on the quality of the systems installation as the build progresses, ensuring all components meet ABYC or CE standards. Pay close attention to the engine installation, wiring, and plumbing. Comparable alternatives might include models from Lagoon, Leopard, or Sunreef, though the EF66 distinguishes itself with its built-to-order flexibility at this price point. This is a significant advantage for a buyer who knows exactly what they want.
