Design and Naval Architecture
Berret and Racoupeau brought a racing sensibility to a cruising brief. The 393's hull features a fairly fine entry at the bow with a broad flat section aft, a shape that rewards reaching and running while delivering surprising upwind ability in moderate conditions. Beam is carried well aft at 13 feet, 1 inch — a deliberate departure from earlier Oceanis proportions that takes a page from long-distance racers of the era. The designers understood that beam for speed works because powerful after sections permit faired waterlines and a flattened stern shape that minimizes wave-making turbulence, while also reducing the need for ballast by generating initial stability through form rather than weight. The waterline stretches to 35 feet, 1 inch, substantially longer than the 381 it replaced, opening up the speed potential that displacement hulls depend on.
The keel is a fin-with-bulb arrangement in cast iron rather than lead — a Beneteau production choice that reduces cost and, according to the company, allows a thinner keel root to minimize turbulence at the junction with the hull. A deep-draft option extends to 6 feet, 3 inches for sailors who want better upwind bite. The mast is deck-stepped, supported by a babystay, a configuration that Practical Sailor considered a compromise on a boat this size, though it simplifies stepping and keeps the interior free of an intrusive mast trunk.
Rig and Handling
Under sail, the 393 proves livelier than her coastal-cruiser billing might suggest. Sailing close-hauled in a 12-knot southeaster past Fort Adams, she tracked as close-winded as the boats around her, and tacked consistently inside 85 degrees. Her balanced spade rudder made tacking a pleasure, and the deep rudder paired with powerful after sections gave steering control that held up well when pushed. Cracking off onto a reach is where the design truly comes alive — hull shape made reaching a blast, and the broad stern sections find their stride with apparent wind forward of the beam.
All running lines lead aft, keeping crew weight in the cockpit, and single-line reefing was quick and easy. The long genoa track and cabin-top traveler permit precise sail trim. The standard mainsail on production versions used a furling system; Practical Sailor preferred the optional "classic" conventional main for its superior effective area, and prospective buyers serious about upwind or heavy-weather performance should factor that choice into their evaluation.
One characteristic that owners should understand from the outset: the 393's light iron keel and form-derived stability mean she heels more than other boats of similar size, though she tends to go faster as a result. In upwind conditions above 17 knots with a built-up chop, she can pound — opening the angle to 55 degrees or more upwind relative to the waves substantially improves comfort. She is a boat that rewards being sailed properly, not one that forgives poor technique with brute inertia.
Accommodations and Interior
Interior volume is the 393's most immediately impressive quality. Headroom in the after part of the saloon approaches 6 feet, 6 inches, and three overhead deck windows flood the space with natural light. Six hull ports, six house ports, and seven overhead hatches combine with two cockpit ports to provide excellent ventilation that makes forecabins and quarter cabins genuinely habitable.
Two accommodation layouts were offered. The two-cabin version places a large athwartship double berth tucked to starboard under the cockpit, a U-shaped galley to port, and a navigation station to starboard; a bar and cabinet forward of the nav station provide storage but occupy saloon space that might otherwise have served as a sea berth. The three-cabin version replaces that arrangement with two fore-and-aft quarter berths under the cockpit, relocates the nav station to port, and substitutes a linear fore-and-aft galley. Practical Sailor found the linear galley more intrusive, less convivial, and less safe in a seaway than the U-shaped version, which also benefits from narrower walkways that give better security when moving below in a swell.
Beneteau's furniture, cabinetry and trim live up to custom standards of fit and precision, the product of a wood shop described as a two-acre operation of computer-controlled milling and routing. Cedar-lined hanging lockers are larger than the class average. Fuel capacity of 36 gallons and water tankage of 119 gallons are adequate for coastal passages, though not designed for extended offshore self-sufficiency. Engine access is superb — attackable from beneath the companionway or via either quarter cabin.
Construction
Beneteau builds the 393 in solid fiberglass reinforced by an internal structural grid, a system the company had refined over two decades of production. The hull-deck joint uses an inward-turning flange bedded in a polyurethane sealant and secured by through-bolts at load-bearing points — cleats, chocks, and stanchions — with machine screws on six-inch centers elsewhere. The joint's integrity depends on chemical bond plus mechanical fastening plus efficiency in meeting shear loads. Balsa core is used in the deck except where hardware is fitted and along the outer rim.
The internal molded liner and bulkheads are bonded to the hull on all sides, providing ample structural support. This is a system that is "designed to be built," and critics can legitimately raise questions about laminate weight and the long-term integrity of the hull-liner bond — but those concerns must be weighed against the enviable track record of durability demonstrated by hundreds of its cousins in the charter trade, a demanding use cycle that exposes construction weaknesses quickly.
Known Issues and Considerations
Several characteristics of the 393 deserve honest assessment. The iron keel demands rigorous maintenance: coatings on iron keels must be scrupulously maintained to prevent the ferrous metal from meeting the water directly. Skipping this inspection cycle invites corrosion that is expensive to remediate.
The deck-stepped mast, while convenient for stepping, requires a babystay for column support; Practical Sailor maintained that a boat this size warrants a keel-stepped mast. Sailors planning extended offshore passages should inspect the rig and all its terminals carefully, and may wish to add an inner forestay for a storm jib — a modification that experienced 393 owners have made when preparing for offshore work in challenging conditions.
The shallow bilge is an inherent consequence of the relatively flat bottom design, though a deep sump is fitted to keep water from reaching vital areas. The standard cockpit layout places mainsheet and traveler controls out of easy reach for a solo helmsman — a shorthanded sailing limitation that Beneteau has since addressed on later models but that remains a real consideration on the 393.
The capsize screening formula sits at 2.02, fractionally above the bluewater threshold of 2.0, confirming what the design parameters suggest: this is an excellent coastal cruiser and capable offshore passage-maker in the right hands, but sailors contemplating serious bluewater work should select the deep-keel option and invest in the safety systems and rig preparation that demanding passages require.
The Verdict
The Oceanis 393 is a well-resolved coastal cruiser that delivers genuine sailing performance alongside a level of interior comfort and light that was genuinely novel when the model was introduced. Berret and Racoupeau's racing background is evident in the hull's handling manners — this is a boat that rewards good seamanship and punishes complacency in heavy weather, which is ultimately a more honest arrangement than a passively stable design that lulls its owner into bad habits. The model's sustained production run reflects market confidence, and its longevity in the second-hand market speaks to owners who have found it broadly satisfying.
