Design and Construction
The First 18 is built predominantly of glassfibre with wood trim, using a solid fibreglass hull and a balsa-cored deck. The hull carries a raked stem and a reverse transom, with a transom-hung rudder controlled by tiller and a choice at the point of sale between a fixed fin keel drawing 2.58 feet or an optional swing keel that extends to 3.61 feet and retracts to 1.83 feet for trailing and shallow work. Groupe Finot laid out a Bermuda-rigged 7/8 fractional sloop with a deck-stepped aluminium mast, one set of swept spreaders, and continuous stainless steel wire standing rigging—a simple, robust rig suited to a boat meant to be launched, raced, and day-sailed by a small crew.
Rig and Handling
The sailplan is compact but versatile: a 108-square-foot mainsail and 81-square-foot jib genoa yield 189 square feet of upwind area, while a 199-square-foot symmetrical spinnaker (factory-optional for downwind) pushes the downwind inventory to 307 square feet. The I foretriangle stands 22.57 feet with a 6.46-foot base, and the mainsail luff runs 22.47 feet on an 8.53-foot foot. With a hull speed of 5.45 knots and a light displacement carried on a short waterline, the design behaves like a pocket racer; in a 2022 review Emmanuel Van Deth wrote that the First 18 is one of the best choices in the pocket cruiser category. The swing-keel version's retraction makes her genuinely trailerable, and the small outboard carried for docking and maneuvering keeps the boat uncluttered aft.
Accommodations
Below, the First 18 sleeps four: a double V-berth in the bow and two quarter berths under the cockpit, served by a folding table and a starboard-side fold-down stove as the entirety of the galley. Cabin headroom is listed at 4.42 inches, which confines her to day-sailing and sheltered overnight use rather than cruising comfort. The wood trim and folding fixtures speak to a boat conceived as a Micro Class racer-cruiser that could still offer four people a place to lie down and brew a meal at anchor.
Known Issues
The known points of confusion are documentary rather than physical. The design is sometimes confused with the much later Beneteau First 18 SE, a distinct boat that should not be mistaken for the 1978–1981 original when reviewing history or class eligibility.
Refits and Ownership
Production consumed about 150 hours per hull, and the boat is now out of production but kept active by the International Micro Cupper Class Association, which organizes racing events for the class. Ownership is straightforward for a trailerable: the swing keel demands periodic pivot and cable inspection, the balsa-cored deck requires guarding against hardware leaks that could wet the core, and the simple wire rig is inexpensive to renew.
The Verdict
The Beneteau First 18 is a tidy expression of Groupe Finot's Micro Class design: a light, easily trailered hull with a real four-berth interior and a lively fractional rig. She rewards the owner who wants one-design-style racing and simple weekend sailing without the overhead of a larger boat, and the active class club keeps her relevant on the water.
Pros
- True trailerability with retracting swing keel (1.83 ft retracted)
- Four-berth layout in an 18-foot hull
- Active class association with organized racing
- Simple, inexpensive wire rig and outboard-only propulsion
Cons
- 4.42-inch cabin headroom limits below-deck use
- Easily confused with the later First 18 SE
- Balsa-cored deck needs leak vigilance
