Design and Construction
The 60 Eco’s defining feature is its solar skin. Developed in-house, the composite-integrated photovoltaic panels are built into the hull sides, superstructure, and hardtop or bimini roof. It was the first 60-foot sailing catamaran in the range fitted this way using Sunreef’s composite-integrated panels.
The solar skin is less than 1mm thick. Sunreef describes it as the industry’s lightest and most efficient solar-power solution and claims that the panels offer a very high degree of resistance to shock and abrasion. Across the documented examples, total solar capacity can reach 17kW, showing how much of the yacht’s exterior is devoted to generating power.
Rig, Propulsion, and Energy Systems
The Sunreef 60 Eco uses twin 70kW electric motors powered by lithium battery banks with a capacity of 140–200kW, depending on specification. Twin 80kW diesel generators serve purely as range extenders.
A powerful, custom-engineered battery bank works alongside the solar skin to support propulsion and onboard appliances. The system is intended to maximize renewable generation and deliver what the builder calls unrivalled energy efficiency, allowing long periods of navigation without vibration or fumes.
Published sail-area figures vary. One technical source lists a 110m² mainsail and a 90m² genoa. Another records an 81m² mainsail, a 33m² genoa, and a 185m² gennaker. The sources differ on the exact sail areas rather than presenting a single fixed inventory.
Accommodation and Layout
The interior accommodates up to eight guests in a spacious four-cabin layout. The galley sits down in the starboard hull, leaving the saloon free for generous lounging and dining areas. Custom-designed interiors and furniture are described as contemporary yet timeless.
Outdoor living is central to the design. The large flybridge includes a wet bar and an immense lounge with another bar and a large C-shaped settee. A sunken lounging area occupies the foredeck, while the full-beam aft cockpit and large swim platform extend the living space beyond the interior.
Verdict
The Sunreef 60 Eco is a thoroughly modern luxury cruising catamaran built around quiet, solar-rich operation without surrendering the volume and comfort of a wide-beam multihull. Its sub-millimeter integrated solar skin, large battery capacity, twin electric drives, and diesel range extenders mark a genuine evolution in liveaboard cruising.
The four-cabin layout and extensive outdoor lounging areas suit owners who want their boat to function as a private resort. When cross-shopped against the Lagoon 60, the Sunreef’s fully integrated Eco architecture is its clearest distinguishing feature.
Pros
- Integrated solar skin less than 1mm thick, built into the hull sides, superstructure, and bimini, with generation capacity of up to 17kW
- Twin 70kW electric motors, 140–200kW lithium battery banks, and twin 80kW diesel range extenders
- Spacious four-cabin layout with the galley down in the starboard hull and a generous saloon
- Extensive outdoor spaces, including a flybridge lounge, sunken foredeck lounge, and full-beam aft cockpit with swim platform
Cons
- The complexity of the integrated solar system, large lithium banks, and twin generators demands strong technical oversight
- Sail-area figures vary between documented sources, complicating exact rig comparisons
