Hull Form and Design Philosophy
Berret gave the First 405 a moderately beamy, purposeful silhouette that sits unmistakably in the Nautor's Swan school of styling — updated and democratized, but retaining the pedigree. The sheerline carries a nice, subtle spring that keeps the boat looking lithe despite its generous displacement, and the ends read as aesthetically balanced rather than pinched or boxy. With a D/L ratio of 183, the hull sits in territory that rewards breeze without punishing the crew in a chop, and the designer appears to have shaped a hull that won't aggravate IOR-derived penalties — a practical consideration for owners who wanted club racing without a full-time rating handicap. The fin keel, available in deep (7'1") and shoal (5'7") configurations, gives owners a meaningful choice between pointing ability and access to shallower anchorages.
Rig and Sail Handling
The sloop rig carries 726 square feet of sail area, producing a SA/D of 16.59 — a figure that the review noted is a little short for hot light-air performance, with a preference expressed for pushing that number toward 19. The practical consequence is a boat that is docile and easy to sail, particularly short-handed, rather than one demanding constant trimming attention in dying breeze. That tradeoff suits the First 405's dual identity as a fast offshore cruiser rather than a pure one-design racer. The companionway notched into the cabintrunk aft yields an especially useful benefit for singlehanders: a great place to sit when you want protection from the wind while keeping the helm in view. Cockpit coamings follow a ramp style that is comfortable for sitting to weather when heeled, though less accommodating in other positions — a detail worth knowing before a long offshore passage.
Deck Layout and Detailing
Among the First 405's less-celebrated virtues is the quality of its deck engineering. A careful look at the deck reveals that detailing is excellent and the general finish level of the tooling is excellent, with many standard items that appear to have been rethought. The most visible example is the companionway and main cabin skylight hatch, which Berret and Beneteau integrated into one unit — a cleaner, stronger solution than the separate components found on competing boats of the era. The result is a deck that rewards scrutiny rather than hiding compromises under gelcoat.
Accommodations
Berret's interior work on the First 405 is what prompted designer Bob Perry to commission a serious competitive analysis — and to admit he could find almost ideal dimensions in each area. The aft head, which on most boats of this size is the first casualty of volume-chasing elsewhere, is more than adequate, complemented by another more than adequate head forward. The galley, often tight on 40-footers that prioritize sleeping quarters, is here described as huge and very well laid out. The quarter cabin offers a berth 33 inches aft of the door and 6 feet, 10 inches long — genuinely usable for an adult crew member rather than a nominal bunk. The central layout concession is a centerline island for the galley sinks and engine box at the base of the companionway — the price paid for the large aft cabin, and one Perry concluded was worth it. The interior throughout is finished in Burmese teak chosen for its incomparable texture and tones, elevating what might otherwise be a purely functional space into something that reflects real cabinetmaking craft.
Construction and Build Quality
Beneteau's production standards in this era are evident in how the First 405 has aged. Perry concluded directly that these boats are strong and sail well — high praise from a designer who had spent time probing the boat for weaknesses. The integrated deck hardware and hatch design speak to an engineering philosophy that anticipated fatigue points and addressed them structurally rather than cosmetically. The Perkins diesel engine installation gives the boat a reputation for mechanical straightforwardness that has benefited owners managing older boats without factory support.
The Verdict
The Beneteau First 405 is a rare production boat that repays serious examination — one where the longer you look, the fewer compromises you find. Jean Berret's layout is as close to ideal as any designer has achieved in a 40-foot offshore cruiser of this generation, and the Swan-influenced exterior ages better than most of its contemporaries. The only material performance concession is a conservatively sized rig that gives up ground in light air, and the ramp coamings favor one sitting position over versatility. For an owner wanting a well-built, handsome, easily handled offshore cruiser with genuine interior liveability, the First 405 remains a compelling choice.
Pros
- Layout efficiency that a professional designer couldn't materially improve
- Burmese teak interior with genuine craftsmanship
- Docile, short-hand-friendly rig
- Well-engineered deck details including integrated companionway-skylight hatch
- Choice of keel drafts for different cruising grounds
- Proven offshore hull with balanced aesthetics
Cons
- SA/D of 16.59 gives up performance in light air compared to more aggressive rigs
- Ramp-style cockpit coamings favor to-weather sitting only
- Centerline galley island/engine box interrupts the companionway approach
