Earlier this year, Jeanneau Boats teased the Sea Loft 480 at boot Düsseldorf. She is a markedly different design from anything else in the Groupe Beneteau satellite of brands, born from a company-wide sustainability objective to reduce Jeanneau’s overall carbon footprint by 30 percent.
Sailboat Sales Director Antoine Chancelier says his team conducted a case-use study with charter boats in Croatia. They found that clients were not sailing. Instead, more than 90% were motoring between destinations to spend their days at anchor, swimming and lounging with the boat as a floating loft.
This led to a shift in design philosophy. Chancelier says the team wanted to keep the boat within the same price point that a monohull sail charter would fetch, and they liked the commodious galleys and wide-open cockpits on catamarans, but twin-hulled boats were deemed too expensive to meet their objectives.
A eureka moment came when they removed the mast and keel. Eliminating both components, including how energy is used during their manufacture and transport, reduced carbon dioxide emissions. It also gave designers a blank canvas to create more living space for social interactions and easy access to the sea. Which is, again, what the charter clients wanted.
The team at Marc Lombard Yacht Design Group took that information and came up with the 480’s “monomoran” hull. She is somewhere between a monohull and a catamaran, with twin hulls aft that merge into a monohull toward the forward third of the boat. According to Chancelier, the design blends catamaran-like stability with a forward section that maintains monohull seaworthiness.
This architecture facilitates a jump in interior volume. The 480’s main deck flows from the cockpit lounge, where folding bulwarks extend her 14-foot, 8-inch beam, and into the salon and walkaround galley on the same level. An open floor plan dominates the salon, with large operable windows that provide excellent views and ventilation. Belowdecks, the standard layout is a quartet of en suite staterooms. Owners can also choose a three-stateroom layout with a full-beam master stateroom. In both configurations, headroom is 6 feet, 6 inches in all staterooms. Both layouts offer optional captain’s quarters in the bow.
With sustainability objectives still driving the brief, her propulsion packages place efficiency at the forefront. The hybrid-electric package includes a pair of 10-kW pod drives and a 22-kW generator, both from Fischer Panda. In full electric mode, a 30-kW lithium battery bank allows for silent cruising for two hours at 7 knots. In hybrid mode, the 480’s range jumps to 215 nautical miles at the same speed. Victron provides a user-friendly interface for energy management for the drives and the 4.2 kW of solar panels. The system will also automatically switch between electric and generator power to minimize the need for manual input.
Jeanneau also offers a pair of 45-hp Yanmar diesels that will increase her cruise speed to 8.5 knots and top speed to 9.5 knots, but that reduce her range to 200 nm. Both power trains have a draft of a skinny 1 foot, 7 inches.
Ten hulls are slated for delivery this year, not to charter fleets, but instead to resorts and hotels for day-tripping or use as bespoke tenders. Three are slated for private owners, with the lion’s share of the 480s delivered with standard diesel power.
The Sea Loft 480 is expected to make her in-water debut this autumn on the Côte d’Azur at the Cannes Yachting Festival.
