The BiLoup 66 is a small French monohull that occupies an unusual niche between the dayboat and the lightweight coastal cruiser. Built by the Wrighton shipyard and designed inhouse by Wrighton, it was produced from 1992 through 1999, with one source narrowing the fabricated span to 1993–1999. At just under seven meters overall — 6.65 meters length overall, 6.60 meters on the hull, 5.80 meters at the waterline — and 2.49 meters of beam, the boat carries a light displacement quoted at 1,200 kg against a heavier documented figure of 1,400 kg, with 500 kg of ballast; sources differ on the displacement value. It is a fractional sloop on a twinkeel (bilgekeel) configuration, a plan that defines much of its character.

Bi-Loup 66 Buyer's Guide

The Bi-Loup 66 is a French-built monohull dayboat and coastal cruiser produced by the Wrighton shipyard from 1992 until 1999, with a 6.60-meter hull, 2.49-meter beam, and a shallow twin-keel (bilge-keel) draft of 0.75 meters. For a shopper considering used Bi-Loup 66s, it presents as a compact, solid-polyester fractional sloop with an inboard engine and a single cabin sleeping two to four — a boat whose used examples will be at least two decades old and whose documentation shows no market prevalence tiers, only fixed design facts.

Layouts on the Used Market

Every sourced example of the Bi-Loup 66 is documented with a single cabin and a berth count of two to four, alongside 1.86 meters of headroom. There is no record of alternative layouts, expanded cabin counts, or factory plan variations. The boat is consistently described as a monohull dayboat and randonneur, so the used fleet should be expected to show one interior arrangement: a compact coastal shelter with convertible berths rather than partitioned staterooms, sized to the 5.80-meter waterline and 6.65-meter overall length.

Equipment and Common Upgrades

The Bi-Loup 66 is documented with an 8 HP inboard engine and an 'Autre type' transmission, a 25 m² working sail plan (11 m² mainsail, 14 m² genoa) and a 30 m² spinnaker. Navigation category is rated minimum C and maximum D. Because no market brief data exists, no item can be assigned a prevalence tier; equipment should be treated as general to the model. Typical used examples will carry the original fractional sloop rig and solid polyester hull, with any electronics, ground tackle, or sail inventories being owner-dependent rather than documented factory options.

What to Inspect

The factual record notes no defects, flooding paths, or structural failures for the Bi-Loup 66. The only inspection-relevant facts are the solid polyester construction of the hull and the twin-keel bi-keelboat appendage plan with 0.75-meter maximum draft. A buyer should apply standard aged-glassboat scrutiny — hull integrity at the keel junctions, rigging wear on the fractional sloop, and inboard engine condition — but no documented known issue obliges a model-specific check beyond those general points.

Availability and Buyer's Takeaway

No typical markets are recorded in the source material, so regional availability cannot be stated. For the buyer, the takeaway is a fixed-generation 1992–1999 French coastal sloop with shallow draft and simple construction:

  • Confirm single-cabin, two-to-four berth layout and 1.86 m headroom
  • Verify 8 HP inboard and 'Autre type' transmission operation
  • Check solid polyester hull and twin-keel junctions for age-related wear
  • Note C/D navigation category limits intended use to sheltered and inland water
