Design Concept and Construction
The Sun Loft 47's spatial concept mirrors a catamaran's open, shareable layout, a resemblance that prompted reviewers to call it a monomaran as well as a monocat. The design concept is credited to Jeanneau working with Philippe Briand, and the deck layout is optimised to ease movement and togetherness on board while preserving private corners. Open to the exterior, the boat maximises sea-going sensation without surrendering cabin seclusion, and a retractable roof spans the saloon and cockpit so owners can dial in shade or openness as they wish. The hull itself draws on Jeanneau's production heritage as a French high-volume builder, with a 47.31-foot length overall, 14.73-foot beam, and a 27,738-pound displacement balanced by 7,738 pounds of iron ballast for a ballast-displacement ratio near 28 percent.
Rig and Deck Layout
What strikes the eye is how far forward the mast sits for a monohull of this size, a choice that frees the central deck for living rather than rigging. The galley is moved above deck, and with the saloon shifted out of the hull the boat gains a huge cockpit that can be reconfigured for differing programs. From stern to bow there are two large seating areas with fold-away tables and seats, and steering is handled at twin wheels; notably there is no fixed chart plotter at the helm, only a holder sized for iPads or tablets. Beneath the cockpit lie two large storage boxes, one wet and one fully waterproof, with the wet locker suited to warps, watertoys, and a dinghy while the dry box swallows luggage, and further stowage hides under each cockpit seat.
Accommodations
Sleeping capacity is the Sun Loft's headline: six double cabins accommodate twelve guests plus a skipper, and four heads with shower compartments are distributed through the hull. Two of those heads open directly from their adjoining cabins. Two aft cabins are reached by ladder and carry their own storage and heads, while the other four doubles use a conventional gangway and share two heads among them, reading a touch more spacious than the aft pair. Two of the six doubles convert between double and bunk configurations. Despite the high berth count and charter intent, the Sun Loft maintains a luxury feel, and the on-deck saloon and galley were relocated specifically to free hull space for those berths.
Equipment and Galley
The above-deck galley is compact but serious for a charter vessel: four fridges with no freezer, though the boxes can be run below zero, one large grilling pan, and a single stove. The versatile cockpit and waterproof dry storage support a boat geared to groups and flotilla use rather than solitary cruising, and the open deck plan lets a skipper supervise a full complement with minimal friction.
The Verdict
The Sun Loft 47 is a niche experiment that succeeds at its assigned task: packing catamaran-style sociability and berth density onto a manageable monohull for charter and flotilla sailing. It will not suit traditionalists, but as a volume-built platform for groups on the water it is coherent and well resolved.
Pros
- Six double cabins and four heads for up to twelve plus skipper
- Catamaran-like open deck and retractable roof over saloon/cockpit
- Above-deck galley and twin-wheel helm with tablet holder, huge reconfigurable cockpit
- Four fridges and dedicated wet/dry cockpit storage
Cons
- No fixed chart plotter at helm, tablet-dependent navigation
- No freezer, though fridges go below zero
- Mast-forward, deck-saloon layout trades private interior volume for berth count
