Design and Construction
The defining construction story of the 60 Eco is its solar skin. The yacht’s integrated photovoltaic panels are built into the hull sides, superstructure, and hardtop or bimini roof, with the first 60-foot sailing catamaran in the line fitted this way using in-house developed composite-integrated panels anchor. The skin is remarkably thin, at less than 1mm, and the builder describes it as the industry’s lightest and most efficient solar power solution, while the Polish company claims a very high degree of resistance to shock and abrasion for the panels anchor. Across the different documented examples, total solar capacity can reach up to 17kW, a figure that underscores how much of the exterior envelope is given over to generation rather than mere structure.
Rig, Propulsion, and Energy Systems
Underway, the Sunreef 60 Eco is driven by twin 70kW electric motors drawing from lithium battery banks of 140–200kW capacity depending on specification, with twin 80kW diesel generators serving purely as range extenders anchor. The sail plan is substantial: one technical source lists a 110m² mainsail with a 90m² genoa, while another records an 81m² main and 33m² genoa plus a 185m² gennaker, and sources differ on the exact areas rather than a single fixed inventory. The solar power system is intended to maximize renewable generation and offer unrivalled energy efficiency for long, vibration- and fume-free navigation as well as for the appliances on board. A powerful custom-engineered battery bank supports operations alongside the solar skin.
Accommodations and Layout
The interior is arranged to welcome up to eight guests in a smart and spacious four-cabin layout anchor. The galley is placed down in the starboard hull, leaving the saloon to offer generous lounging and dining areas with custom-designed interior and furniture described as both contemporary and timeless. Outside, the alfresco relaxation spaces are a core part of the design: a large flybridge with a wet bar and an immense lounge with a bar and large C-shaped settee, a sunken lounging area on the foredeck, and a full-beam aft cockpit with a big swim platform extend the living space well beyond the cabin sole.
The Verdict
The Sunreef 60 Eco is a thoroughly modern luxury cruising catamaran whose identity is built around silent, solar-rich operation without surrendering the volume and comfort of a wide-beam multihull. Its integrated sub-millimeter solar skin, large battery capacity, and dual electric drives with diesel range extenders make it a genuine evolution in liveaboard cruising, while the four-cabin layout and expansive outdoor lounging suit owners who treat the boat as a private resort. Cross-shopped against the Lagoon 60, the Sunreef’s fully integrated Eco architecture is its distinguishing argument.
Pros
- Integrated solar skin under 1mm thick built into hull sides, superstructure, and bimini for up to 17kW generation
- Twin 70kW electric motors with 140–200kW lithium banks and twin 80kW diesel range extenders
- Spacious four-cabin layout with down-starboard galley and generous saloon
- Extensive alfresco spaces: flybridge lounge, foredeck sunken lounge, full-beam aft cockpit with swim platform
Cons
- High system complexity from integrated solar, large lithium banks, and dual generators demands strong technical oversight
- Documented sail-area figures vary between sources, complicating exact rig comparison
