Beneteau 343 Sailboat Review, Specs, and Listings

Hull, Construction, and Underbody

The 343 hull is voluminous with generous freeboard and beam carried well aft, with maximum width somewhere near the companionway. Underwater, the narrow keel section flares aft along its foot, and the balanced rudder is placed well aft to give confident steering, particularly on a deep reach. The standard keel draws just under five feet; a deeper six-foot keel is also offered for sailors who want more bite upwind. Construction follows Beneteau's long-proven formula: solid laminate hull with a structural fiberglass liner glassed in place, the bond between them achieved with a proprietary polyester compound that chemically links hull to liner. The deck is balsa-cored with solid fiberglass reinforcements at high-load areas, bulkheads bonded to hull and deck through 360 degrees, and hull and deck laminated together rather than relying on a mechanical joint alone.

Rig and Deck Handling

The 343 carries a nine-tenths fractional sloop rig that barely qualifies as fractional — nearly masthead in practice — supported by discontinuous stainless steel wire. The mast and boom are manufactured by US Spars, and a Profurl roller furler handles the headsail. A rigid boom vang contributes to sail shape and holds the boom aloft when reefing, its controls led to the cockpit. Chainplates are mounted inboard to produce tight sheeting angles and improve upwind performance. All sail controls are led aft through line organizers to the cabintop, where Lewmar 30 self-tailing winches handle halyards and mainsheet, and Lewmar 40 primaries manage the genoa sheets. The mainsheet traveler sits atop the cabin trunk forward of the companionway, freeing up the cockpit but making the mainsheet a stretch from the helm when sailing shorthanded — a genuine ergonomic compromise.

The cockpit itself is 85 inches on centerline from stern to companionway, with six-person capacity and outward-slanting seat backrests. Beneteau's patented pivoting wheel pedestal opens access to the swim step, and the helmsman's seat swivels to provide a straight shot to the companionway. An emergency tiller stows within reach in the cockpit locker, and a manual bilge pump lives under the helm seat — a safety item that seems to have gone the way of the hula hoop on most production boats of the era, but not here.

Accommodations

Below, the 343 is bright and livable. Five overhead hatches, eight opening ports, four hull ports, and large skylights in the saloon produce ventilation that is genuinely excellent. Joinery is finished in douka, a cousin to mahogany with a cherry stain, and the fit is consistently well-fitted with reliably uniform surface finishes since Beneteau adopted computer-controlled cutting. Headroom reaches six feet six inches in the galley and aft cabin, with the saloon offering six feet five.

The L-shaped galley sits to port immediately below the companionway, equipped with a two-burner gimbaled propane stove-oven, single sink, and a 4.5-cubic-foot front-opening refrigerator. The nav station to starboard provides a 26-by-20-inch chart table, and wooden grabrails run the length of the saloon on either side, spaced far enough from the hull to provide a secure handhold when heeled. The aft stateroom is the 343's showpiece: an athwartships double berth measuring six feet seven by seven feet one, hanging locker, open shelving, and impressive headroom — you don't stoop to move about. The forward V-berth provides a second double, and the head features a separate shower with its own overhead hatch, positioned to double as a wet locker. The one interior caveat: the starboard settee narrows to fourteen inches forward, making it suitable only for a child as a berth.

Performance Under Sail and Power

On the water, the 343 delivers. In eight to fourteen knots of breeze she beats to weather within 35 degrees of the apparent wind and accelerates quickly out of a tack. Boat speed in those conditions runs five to seven knots across all points of sail, and the boat proved stiff enough that no reef was considered even in 14-knot wind with chop. The helm is light and nicely balanced across a wide range of conditions, with enough power to punch through chop when overpowered with the big genoa. A sail area-to-displacement ratio of 18.43 puts her in the middle of the performance band — not a racer, but not a slug either. The Yanmar diesel is quiet enough at 2,500 rpm to converse at normal voice levels in the cockpit and below, and under power she maneuvers with enough responsiveness to back from a tight slip without incident. The 20-gallon fuel tank is the most frequently noted limitation for passages of any length.

Known Quirks and Considerations

A handful of design trade-offs come with the package. Engine access requires removing a panel at the foot of the aft berth, which is inconvenient, and the battery bank and fuel tank also reside under or near that berth, reducing the aft stateroom's underberth storage. The rudder stock is composite — an increasingly common practice, but one that warrants attention from any prospective buyer doing a survey. The fiddles on the saloon bookshelves would benefit from a large dose of vitamins, per Practical Sailor — they're undersized for offshore conditions. Primary winches at Lewmar 40 seem just a tad undersized given the sail plan. And the split backstay limits rig adjustability underway while easing stern access.

The Verdict

The Beneteau 343 is an honest, well-executed coastal cruiser that succeeds at exactly what it sets out to do. It is roomy below for a 35-footer, sails with genuine spirit, handles easily shorthanded, and is built to a standard that has probably logged more miles than any other builder's and holds up well. It asks for compromises — the mainsheet stretch, the tight aft stateroom storage, the modest fuel capacity — but none of them are dealbreakers. For the sailor who wants a comfortable, capable weekender with Bahamas-range cruising potential, the 343 is a legitimate contender.
