Hull Design and Architecture
The hull evolved from the First 310, itself descended from the same pool of ideas that produced the competition Figaro. Beneteau and Finot-Conq opted for a single-skinned hull with a balsa-cored deck and an integral GRP structural grid, a construction approach that keeps weight honest while providing the stiffness a performance hull demands. The waterline runs a long 8.80 metres against the 9.61-metre overall length — a straight stem with minimal overhang that maximises sailing length relative to rated length. Beam is a moderate 3.23 metres, not excessive by current standards, but the volume is carried high in the topsides above the waterline so that heel engages the broad aft sections and stiffens the platform precisely when it needs stiffening. The high freeboard and broad transom contribute to this effect and give the interior a spaciousness that belies the boat's length.
Rig and Sailing Characteristics
The First 31.7 carries a keel-stepped Sparcraft fractional sloop rig without runners, relying instead on a double-spreader arrangement without extreme spreader sweepback. The forestay attaches just a few centimetres below the black band, making it nearly masthead in practice. Standard sail inventory included a 140 per cent overlapping genoa for a working sail area of around 500 square feet; the keel and rudder were made deeper with a heavier bulb compared to its predecessor, adding righting moment that allows the sail plan to be pushed hard. On the water the boat responds predictably: she heels until the broad aft section catches and accelerates, tracks cleanly upwind, and shows no desire to round up or stagger in gusts. In stronger downwind conditions the hull can accelerate and plane on a deep reach — behaviour once considered impossible in a ballasted monohull of this displacement.
Cockpit and Deck Layout
The cockpit is wide and short, opening onto a small integrated swim platform in the transom. A full-width traveller runs from coaming to coaming across the bridgedeck, which creates an occasional obstacle but enables useful end-boom sheeting and allows the traveller to be eased to a productive angle. Twin Lewmar winches on the cabintop handle halyards and reefing lines that lead aft via three jammers; primary sheet winches are self-tailing Lewmars as well. The backstay tails are led through the transom to cams on the bridgedeck, accessible to both helmsman and crew. One characteristic worth noting: the cabin-top surfaces are curved and become slippery when wet, making foredeck work require deliberate footing. The boat was offered with tiller steering only, which suits racing but limits cockpit space for cruising crews.
Accommodations
The interior demonstrates the Beneteau gift for extracting a comfortable and stylish cabin from a racing platform. The forward V-berth master cabin has just under six feet of standing headroom, a large overhead hatch for ventilation, and lockers on both sides. The main saloon centres on a drop-leaf table on the centreline with integrated bottle stowage, flanked by twin straight settees long enough to seat four for dining. The galley runs to port with a 12-volt refrigerator, single sink, and two-burner propane stove and oven. A second private aft cabin with a double berth and hanging locker is separated from the saloon by the head compartment, which combines shower and toilet in one compartment. A forward-facing nav station rounds out the below-decks picture — an asset that felt mandatory on boats of this era and remains genuinely useful. The headliner is a white moulding with timber strips, and cherry wood veneer finishes the hull sides throughout, giving the interior a refinement level that surprised observers accustomed to seeing the boat beaten up on Wednesday-night beer-can courses.
Known Limitations
Several practical compromises follow from the racing DNA. Tankage is light at eight gallons of fuel and 42 gallons of water, which demands careful planning on passages where refuelling is not convenient. Crew comfort under sail is constrained by the tiller: it takes up cockpit space that a wheel installation would free up, and people with short legs struggle to brace themselves across to the opposing seat when the boat heels. The capsize screening formula calculates to 2.10, which sits marginally above the conventional 2.0 threshold for offshore passages — not alarming, but worth noting for anyone contemplating extended blue-water work rather than coastal racing. The comfort ratio of 18.56 confirms the boat's lightweight, performance character; expect a lively motion in a short chop.
The Verdict
The Beneteau First 31.7 makes good on a difficult promise: a legitimate club racer with a Finot-Conq pedigree that can be handed to a family on a Sunday morning without apology. The hull traces its heritage to professional solo offshore racing, delivers a sail area-to-displacement ratio firmly in the performance range, and rewards a competent helmsman with planing runs and crisp upwind tracking. It will never be mistaken for a blue-water passage-maker — the tankage, comfort ratio, and capsize screening figure all point toward coastal and inshore work — but within that envelope it excels at both of its intended roles simultaneously.
Pros
- Finot-Conq racing hull derived from the Figaro circuit; capable of planing downwind
- Generous interior volume for the length, with two private cabins and a nav station
- High-quality fit and finish with cherry veneer and white moulded headliner
- Nearly masthead fractional rig with no runners; straightforward to handle short-handed
- Deep L-shaped bulb keel with a 6.23-foot draft that improves windward performance over its predecessor
Cons
- Tiller-only steering reduces cockpit space for cruising use
- Minimal tankage (8 gallons fuel, 42 gallons water) limits coastal range
- Curved, slippery cabin-top surfaces demand care when moving forward in wet conditions
- Capsize screening figure marginally above offshore threshold; best suited to coastal sailing
- Low comfort ratio reflects racing-weight motion; not ideal for those prone to seasickness in short seas
