80 Sunreef Power Review: The 4,000-Square-Foot Catamaran That Redefined Multihull Cruising

“The 80 Sunreef Power is one of the few catamarans in this size range that actually delivers on the promise of liveaboard volume without sacrificing seaworthiness. The composite construction is light enough to hit 23 knots with twin 1,200 hp engines, and the hull form is stable enough that you’re not rolling at anchor in two-foot chop. The Eco version is the real story here—Sunreef has figured out how to integrate solar into every surface without turning the boat into a science project, and the 990 kWh battery bank on Eco Sol is legitimately the largest in the market. This is not a concept boat. It works.

This boat is for the owner who has already owned a 60-foot cat and realized that the jump to 80 feet is not about length—it’s about beam. The 39-foot beam gives you four real guest cabins, a full-beam master, and crew quarters that don’t share a wall with the owner’s suite. It is not for the owner who wants to run 30 knots to Bimini every weekend. It is for the owner who wants to anchor in the Exumas for two weeks and never hear the generator. If you are comparing this to a Lagoon 78 or an Aquila 70, the Sunreef is the custom option. If you are comparing it to an 80-foot Azimut, the Sunreef is the one with twice the space and half the fuel burn.

Resale on the 80 Sunreef Power is strong because the boat has a track record. Sunreef has delivered more than 20 hulls since 2019, and several are in commercial charter, which means the market has real data on operating costs and reliability. The Eco version will hold value better than the diesel version over the next decade as electric propulsion becomes table stakes in this segment. Maintenance is straightforward if you have a good yard relationship—Sunreef builds everything in-house in Poland, so parts availability is not an issue. Expect $500,000 to $700,000 per year in total operating costs with crew, insurance, dockage, and maintenance. The Eco version cuts that by 30 percent if you eliminate fuel and reduce engine service intervals.”
