2026 Diamond Yachts EF66 Power Catamaran

The Diamond Yachts EF66 is a 68-foot power catamaran built in fiberglass, designed around the spacious platform that a catamaran hull provides. The yacht accommodates five cabins and five heads, making it well-suited for extended cruising with family or guests. Its 32-foot beam delivers the interior volume and stability characteristic of the catamaran form.

Power comes from Cummins engines, proven marine powerplants known for reliability. The design emphasizes contemporary styling and layout flexibility, allowing owners to configure the interior spaces and finishes to match their preferences and cruising priorities.
