Electric Yachts and Catamarans

solar · catamarans · foils · hotel loads

Pure battery-electric yachts are either solar catamarans that cruise slowly or foiling boats that fly. Hotel loads, not propulsion, decide the battery size at anchor.

Energy-flow diagram for a solar-electric catamaran: a solar roof (Silent Yachts; Heysea's 1.9 kW hardtop array) and marina shore power feed a battery bank (Heysea Seaview 59: 58 kWh of LFP in five packs), which supplies twin electric drives and hotel loads such as air conditioning, galley and water. Notes: Silent claims up to 100 miles a day on solar alone; Heysea's battery runs air conditioning for up to eight hours; Navier's N30 uses foils instead of solar and claims 75 nautical miles at 20 knots.

Finding

Battery-electric yachts work in two narrow forms - wide solar catamarans that trade speed for free energy, and light foiling yachts that cut drag - while most larger yachts sold as electric still carry generators

Silent Yachts' 62-foot catamarans cruise on a roof-sized solar array and claim up to 100 miles a day; Heysea's Seaview 59 pairs 58 kWh of LFP with 1.9 kW of solar and ePropulsion drives. Navier's 30-foot N30 sells at $850,000, foils at speed and claims 75 nm at 20 knots.

On a yacht the battery serves two masters. Propulsion at displacement speed needs only a few kilowatts, but air conditioning, refrigeration, water makers and galleys run all night, and in the tropics the hotel load can exceed the propulsion load. That is why Heysea quotes eight hours of air conditioning rather than a range, and why Silent offers an optional range-extender generator. Boats that add a generator as standard - Sunreef's Eco line, Greenline and most superyacht electric-drive projects - are hybrid-electric and sit outside this battery-electric list.

Silent Yachts' assets were bought out of financial trouble by owner-investor Michael Said through Helios Yacht Investments, with production at the Silent Italia yard in Fano and an 80-foot model announced. China's entry comes from Heysea Yachts in Guangdong, which builds the Seaview 50 and 59 electric catamarans with Dongguan-based ePropulsion, and from Sea Expandary, the Shenzhen and Zhuhai yacht venture JD.com founder Richard Liu launched in 2026.

Navier is the software play: automated foil control, autopilot and docking assistance, with remote monitoring for fleets. Its June 2026 agreement with JIH Global commits $100 million for 100 N30s across the Maldives over three years, in resort and water-taxi duty closer to ferry work than private yachting.
