Finally, a real 100% electric yacht! - Greeline 45 Fly Tour

Launched in 2019, the Greenline 45 Fly is built in Begunje, Slovenia, with naval architecture and exterior design by J&J Design and interiors by Marco Casali’s Too Design. Its 15.57-metre overall length includes the extended bathing platform, while the hull measures approximately 13.54 metres. Construction is vacuum-infused glass-reinforced plastic, with a published light displacement of approximately 13.5 tonnes, depending on specification.

The accommodation centres on a full-beam owner’s cabin amidships and a forward VIP, both with island-style double beds. The two-cabin arrangement provides walk-in wardrobes; an alternative layout substitutes a third guest cabin. Two bathrooms have separate shower compartments, and a convertible saloon can provide two additional berths beyond the four or six below. Large windows bring daylight into both the saloon and principal cabins.

On the main deck, the aft galley serves the saloon and cockpit, connecting indoor and outdoor dining areas. A starboard helm door and adjacent boarding gate shorten the route between the driving position and the quay. Above, the flybridge combines a second helm, seating, sunbathing space and a wet bar. A bimini or optional hardtop provides shade, while the foredeck offers another sunbathing area.

Diesel installations have included twin Yanmar 8LV320 and 8LV370 engines, larger 6LY440 engines, and Volvo Penta IPS alternatives. BoatTEST’s twin-370 hp shaft-drive example reached 23 knots and returned a calculated range of approximately 781 nautical miles at 7.3 knots, allowing a fuel reserve. Its consumption increased substantially at faster cruising speeds. Shaft-drive versions use propeller tunnels, whereas IPS installations employ a different underwater configuration without those tunnels.

Electric specifications must be matched to the boat’s build year and equipment. Greenline’s 2022 brochure documented an E-Drive installation with two 100 kW motors, 160 kWh of batteries, an 11-knot maximum and approximately 30 nautical miles of range at a seven-knot cruise. A separate H-Drive hybrid specification combined diesel engines with two 14 kW electric machines, up to 80 kWh of batteries and up to 25 nautical miles electrically at five knots. An optional range-extending generator is not emission-free when operating. (greenlinesweden.se)

The related 45 Coupe followed in 2020, replacing the flybridge with a larger solar roof. Flybridge equipment has also evolved, including later-generation hybrid systems and an optional solar-panel hardtop. Domestic refrigeration, induction cooking, an inverter and solar charging support life aboard, although battery endurance depends on installed capacity and electrical loads. For cruising and anchoring, the distinction between propulsion batteries, domestic power and generator equipment is therefore central to comparing individual examples.
