The Greenline 58 Fly is conceived as a modern long-range cruiser that blends efficient hull design with generous living spaces across her flybridge, main deck and lower accommodations. At just over 18 meters in length with a broad 5.1‑meter beam, she offers a stable platform with easy movement from the cockpit through the open-plan saloon to the forward helm, emphasizing comfort on extended passages and at anchor.

Below deck, the Greenline 58 Fly is arranged around three spacious cabins, each with its own bathroom, delivering a level of privacy more often associated with larger yachts. Large hull windows and thoughtful detailing bring natural light into the staterooms, while the wide beam creates notable volume in the full-beam master suite. The layout is optimized for family cruising or hosting friends, with six permanent berths and ample storage for longer trips.

Power is provided in standard form by twin diesel inboard engines, with configurations such as twin MAN i6 units around 730 hp each commonly specified, delivering a balance of performance and efficiency suited to passagemaking. Greenline’s design allows for advanced energy-management solutions, including extensive solar capacity and battery systems on the 58 Fly, supporting quieter operation and reduced generator use while maintaining onboard comforts.
