The Tanna 47 is a 45-foot catamaran built in fiberglass with a 25-foot beam, powered by twin Yanmar diesel engines. This 2026 model features the three-cabin, three-head Maestro layout and comes with an extensive list of factory-installed equipment and custom upgrades throughout.
The interior has been redesigned with premium materials: American walnut joinery, Alcantara upholstery, and genuine leather accents. All cabins are carpeted, and door hardware has been upgraded to Foresti & Swardi stainless fittings. Hatches are reinforced Lewmar units with stainless handles. Toilet systems include a Planus quiet unit in the master cabin and Sanimarín models in the guest heads. Curtains have been upgraded to superior fabrics throughout.
The boat is equipped with substantial systems for cruising: a 30 kW lithium battery box with a 10 kW Victron inverter-charger, an 11 kW generator, Frigomar air conditioning units, and an inox-framed solar installation. Navigation electronics include B&G instruments, radar, and full wiring. Double-layer soundproofing lines the engine compartments, and security features include a BRNKL Black system with smartphone access and Certec lightning protection.
Deck equipment encompasses UK Sails carbon sails, a Faknor electric genoa furler, Harken sliding mainsail system, an electric windlass, additional electric winches, and a Lewmar swim ladder. Entertainment includes a Cambridge Audio amplifier, Elipson speakers for the cockpit, a Pro-Ject turntable, and an Epson projector with motorised screen.
