Sunreef 43M Eco 004 Sailing Catamaran

The Sunreef 43M Eco 004 is built around a different kind of engineering: two 400kW electric motors and solar panels, built to run on regenerated and solar power rather than diesel alone. Sunreef is building her now, hull number four of the design, for delivery in 2027.

Build and provenance

Sunreef Yachts builds the Sunreef 43M Eco 004 as a sailing catamaran, at 498 gross tons with a beam of 15.4 metres and a draught of 3 metres, proportions that come from twin hulls rather than a single one. She is still under construction, hull four of the series, so there is no service history yet to weigh, just the build specification itself.

Layout and accommodation

Twelve guests are accommodated across six cabins, laid out across the beam that a catamaran hull provides.

Performance and engineering

Her two 400kW electric motors, fed by solar panels and regenerative charging under sail, give her a cruising speed of 12 knots and a top speed of 13 knots. It is a propulsion plan built around silence and range rather than outright pace, in keeping with a sailing catamaran that can also motor under her own power when the wind drops.

On deck and at anchor

A walk-around beach club joins the aft platform, the side skirts and two fold-down balconies into one space at the water's edge, with a pool and deck jacuzzi close by. Below, a gym and a sauna and steam room cover the wellness side, and a cinema, jet skis, scuba equipment and an onboard therapist are also aboard for guests who want more than the water off the platform.

Where she lies and how to see her

She is under construction in Poland, and Boatcrowd handles enquiries on the Sunreef 43M Eco 004 through to delivery. We arrange yard viewings and attend them with you, and once an offer is accepted a survey and sea trial follow before handover.
