Design and Hull Character
The First 375's origins show clearly in the hull lines. The IOR-influenced narrow stern is unmistakable — a shape optimised for windward performance rather than the broad, buoyant sterns that later became fashionable. That tradeoff is real: the boat excels going to windward and is measurably less dominant on a reach or run, particularly in light air. The deep fin keel and large spade rudder deliver the responsiveness you would expect from a race-derived platform, with light, sensitive helm feel and well-balanced rudder feedback that reward an attentive helmsperson. The two keel options — a deep 6 ft 5 in draft and a shallow 5 ft 6 in alternative — give prospective owners a meaningful choice between performance and shoal-water access. The boat was popular with both cruising and racing skippers and enjoyed success in both fields, which says something about the breadth of the design.
Construction
Beneteau was on the cusp of introducing vacuum bagging when the First 375 was built, and the hull is hand-laid solid glass and resin with substantial scantlings in high-stress areas. The extra resin that characterised pre-vacuum production simply added to structural integrity. Below the cabin sole, four substantial hollow fiberglass ribs run athwartships, complemented by two solid longitudinal stringers that form anchor points for the large stainless steel chainplates. The deck is balsa cored with solid fiberglass at hardware attachment points, and the hull-to-deck joint — an inward-turned flange bonded and fastened through the aluminum toe rail every four inches — has proven leak-free through years of rough offshore sailing. The keel attachment relies on a moderate stub; the keel bolts on well-maintained examples appear factory fresh and show no structural fatigue. The overall impression is of a boat somewhat overbuilt for its size, which pays dividends over decades of use.
Rig and Handling
The standard double-spreader, keel-stepped mast rises 49 feet above the deck, carrying a masthead sloop rig with a sail area just over 648 square feet split nearly evenly between foretriangle and mainsail. A baby stay, adjustable from the cockpit, prevents mast pumping in heavier seas — a considered detail on a boat designed to sail offshore. The genoa tracks run from the chainplates aft along the cabin trunk, giving good flexibility in sheeting angle; dedicated self-tailing winches on the cockpit coaming handle spinnaker sheets. On the water, the First 375 heels slightly and settles into a groove to windward, surging forward with the genoa telltales drawing cleanly. The big genoa can be a handful, a characteristic Beneteau owners learn to manage through early reefing or switching to a working jib. Upwind, the boat is very controllable in substantial seas and holds course without drama, a trait that matters on an offshore passage far more than top-end VMG numbers.
Accommodations
Two interior configurations were offered. The galley-to-port layout provides a generous double aft cabin and an enormous cockpit locker to starboard; the alternative puts the galley to starboard and delivers three separate cabins at the cost of the cockpit locker. In either arrangement the head is aft, opposite the galley — a sensible offshore arrangement. The main cabin's U-shaped settee seating six comfortably around a table mounted to the mast gives a social interior suited to family use. The galley is genuinely functional: a deep double sink, generous countertop, and gimbaled two-burner stove with oven are surrounded by exceptional storage. Throughout, warm teak cabinetry defines the interior character — a hallmark of production boats of this era that ages well with proper care. Forward, the v-berth stretches to queen width at the shoulders, though it narrows toward the feet. Stowage was unusually good for the class. Ventilation relies on deck hatches and opening ports rather than Dorade boxes, which limits below-decks airflow when sailing in rain.
Known Issues and Maintenance Considerations
Age surfaces predictable trouble spots on the First 375. Cabin liners — vinyl bonded to open-cell foam — fail over time, with the vinyl separating from the backing on both hull sides and overhead surfaces. Owners have addressed this with closed-cell foam panels finished in vinyl, screwed in place to maintain the original look. The stanchion bases, cast aluminum set against the toe rail, are known to crack and should be monitored; replacements are widely available. The small factory black water holding tank is inadequate for coastal cruising and relocation of a larger tank to the cockpit locker is the standard solution. Teak cockpit seat strips, bedded in a black compound that deteriorates and separates with sun exposure, require ongoing attention. Chainplate inspection is limited by a cut-out in the cabinetry that provides only cramped access — a point worth examining carefully on any purchase. Water tanks varied across the production run; bladder tanks fitted at the factory are candidates for replacement.
Refit and Upgrades
The First 375's mechanical setup is straightforward and well-regarded. The original Volvo Penta 2002 diesel, at 28 hp, is capable of reaching hull speed and has proven durable over many offshore miles. When the auxiliary approaches end-of-life, the Beta 30 has been documented as a direct-replacement on the same engine beds, shaft, strut, and propeller, requiring minimal engineering. The companionway stairs are removable for engine access, and an opening cabinet in the aft cabin provides a second route in. Owners doing offshore passages commonly replace the fixed three-blade propeller with a feathering or folding alternative to reduce drag under sail. The mainsheet traveller on the companionway bridge deck is awkward for shorthanded sailing and has been relocated by several owners to a position forward of the companionway hood with lines led back to the cockpit — a practical upgrade. The factory bow roller arrangement is compatible with a furling headsail and a double roller for anchoring; a retractable bowsprit can be added for an asymmetric spinnaker, though this can obstruct one of the bow rollers.
The Verdict
The Beneteau First 375 occupies a particular place in the Beneteau heritage: it was designed when the company first brought in outside racing designers, and the result shows genuine offshore DNA beneath a thoroughly liveable interior. It rewards the helmsperson who likes to sail to windward and tolerates the IOR stern compromise on downwind legs. At this age, condition and refit history matter enormously — those in need of a refit should be priced accordingly — but a well-maintained example has demonstrated the ability to circumnavigate island chains and make offshore passages of hundreds of miles without drama.
Pros
- Race-bred hull excels at windward performance with light, responsive helm
- Solid glass hand-laid construction with substantial scantlings throughout
- Two practical interior layouts, unusually good stowage for the size
- Straightforward engine replacement path (Beta 30 direct fit)
- Proven offshore capability in capable hands
Cons
- Narrow IOR stern limits off-wind speed, especially in light air
- Cabin liners prone to delamination on older, less-maintained examples
- Cockpit is compact by modern standards; coaming height falls short for back support
- Chainplate inspection access is cramped
- No Dorade vents limits below-decks ventilation underway in rain
