Bi-Loup 66 Buyer's Guide
Shopping the used Bi-Loup 66 market means looking at a pocket cruiser from the Wrighton yard's 1992–1999 production run: a 6.6-meter fractional-sloop dayboat with twin bilge keels, a single cabin, and a stated light displacement around 1,200 kg. These are small, shallow-draft coastal boats, and the used pool is thin, so a buyer should focus on hull condition and the few specification points that separate a sound example from a tired one.
Layouts on the Used Market
Every Bi-Loup 66 on the market will show the same core plan: one cabin, two to four berths, and 1.86 meters of headroom beneath a solid fiberglass deck. The hull is solid monolithic polyester on a bi-keelboat appendage with a 0.75-meter maximum draft. There is no alternative layout or extended-cabin version documented, so condition and rigging state are what differentiate individual boats rather than floor-plan choice.
Equipment and Common Upgrades
The only factory-listed propulsion item is an 8 HP inboard engine with an "other type" transmission, and the rig carries a 25 m² upwind suite — 11 m² main, 14 m² genoa, plus a 30 m² spinnaker. Buyers should treat the engine make and transmission detail as unknown until verified in person, and judge any added canvas, wind instruments, or battery banks as owner fitments rather than standard spec.
What to Inspect
Look closely at the twin keel-to-hull joints for past grounding damage, confirm the 0.75-meter draft bilge keels are sound, and verify the 8 HP inboard and its transmission respond cleanly. Ordinary wear on a 25- to 30-year-old solid-polyester hull is the main risk, not a design flaw.
Availability and Buyer's Takeaway
Treat any listing as a scattered individual sale rather than a concentrated market.
- Confirm the bilge-keel joints are undamaged
- Verify the inboard starts and shifts smoothly
- Check the polyester hull for stress or repair
- Confirm 1.86 m headroom and berth count
