Design and Construction
The hull is hand-laid solid fiberglass, and the deck is resin-infused with a balsa core, with high-density plywood inserted wherever hardware mounts solid, hand-laid construction. The laminate schedule includes two outer vinylester layers to stave off blistering, while bulkheads are bonded into the deck and hull with polyurethane adhesives and a molded structural grid tames rig and keel loads. The cored deck is built in a two-part injection mold using Jeanneau’s proprietary Prism Process, which yields an optimal resin-glass ratio and a smooth finish both above and below. The canoe body is conventional for current French cruisers, with a plumb bow maximizing sailing length and hard chines aft that dig in under sail and set off an angled reverse transom. Both available keels are cast iron, encapsulated in epoxy, drawing either 7 feet 5 inches or 5 feet 8 inches.
Rig and Handling
The deck-stepped, slightly fractional double-spreader rig carries a Z-spar aluminum mast with wire rigging and mid-boom sheeting; chainplates sit outboard and the genoa tracks run close alongside the cabintrunk for tight sheeting angles. Winches normally found on the cabintop have been relocated to the coamings, and the double-ended mainsheet and jib sheets lead under the deck to stoppers and a winch just forward of each wheel, so a shorthanded crew can manage her easily. Twin helm stations are set well outboard of the split backstay with excellent sightlines, and a large single rudder gives authority. Test sailors found the boat unstressed with a four-man crew even as wind built, clipping 7.5 to 8 knots beating in 15 knots and maneuvering into a fuel dock with bow thruster and rudder a snap powered through waves as opposed to vaulting over them. Motorsailing under main alone delivered 7.3 knots at 1,800 rpm with acceptable engine noise.
Accommodations
Below, the interior is refined and elegant with ergonomic design for longer cruises, and the joinery is outstanding for a modern production boat thanks to CNC-cut parts. The owner’s cabin forward is vast and bathed in light, with a nearly 7-foot double berth, generous hanging locker, and copious storage; double hatches overhead aid ventilation. The saloon carries four opening hatches, a front-facing nav station, a port settee, and a U-shaped table for six, while the C-shaped galley to starboard has an Eno stove and deep storage. Aft, owners choose one VIP cabin or two guest cabins with good headroom; the standard starboard quarter space is a workshop reachable from the cockpit, with a utility room just ahead that can take a washer or day head. The cockpit extends via cutouts in the cabintrunk bulkhead, seats six to eight at a table with refrigerated well, and the aft deck “terrace” folds down with the swim step to make a waterside lounge.
Equipment and Layout Options
The boat is offered with two or three cabins and heads, and options include Alpi oak or teak finishes, a washing machine or wine fridge, and greater tank and battery autonomy. On deck, the transom houses a massive articulated split-level swim step, helm seats hinge clear of it at anchor, and the cockpit table holds a life-raft locker. Multiple sail plans are available — standard in-mast furling main and 110 percent genoa on a Facnor furler, with provision for a self-tending jib track or removable inner forestay and a fitting on the double anchor roller for downwind sails.
The Verdict
The Jeanneau Yachts 51 is a thoughtfully engineered modern cruiser that pairs serious shorthanded capability with a bright, well-built interior and a versatile aft-deck social space. She suits couples who want to live aboard for extended periods without sacrificing performance or guest comfort.
Pros
- Hand-laid solid hull with blister-resistant vinylester outer layers and structural grid
- Easily shorthanded via relocated winches, under-deck sheets, and large rudder with bow thruster
- Refined, ergonomic interior with copious storage and flexible two/three-cabin plans
- Innovative folding terrace and articulated swim step for at-anchor living
Cons
