The searches provided some useful information, but a significant amount of detailed interior layout information and specific owner perspectives for the Bi-Loup 10 are still somewhat limited. I found general information about the Bi-Loup range and Wrighton's philosophy, which is good.

Here's a breakdown of what I found and what's still missing for a truly comprehensive article:

Found:

  • Designer: Richard Wrighton is the designer of the Bi-Loup 10.
  • Production: 1990-2003.
  • Variations: Later models were called Bi-Loup 10.2. The builder article also mentions the Bi-Loup 109 as a later evolution.
  • Builder Philosophy: Wrighton is known for robust, accessible twin-keel sailboats, emphasizing safety, comfort, and shallow draft capabilities for family cruising.
  • Performance (Ratios confirmation): SailboatData.com lists it as a "light sailboat which is a good performer. It is reasonably stable / stiff and has a low righting capability if capsized." This generally aligns with my ratio interpretations.
  • Headroom: 5.58 ft (1.70 m).
  • Twin-Keel advantages: Stability, reduced draft, ability to dry out on tidal moorings, 6].
  • The Bi-Loup 10 is described as a "voilier de croisière biquille" (twin-keel cruising sailboat) designed for "navigation familiale ou en équipage" (family or crewed sailing).

Missing/Limited:

  • Designer's specific philosophy for this model: While Richard Wrighton is noted, detailed design goals for the Bi-Loup 10 specifically are not explicitly stated beyond the general Wrighton ethos.
  • Detailed interior layout: The search results give some very high-level info about "luminosity" for later models (109) and "new interior layout" for the 90, but not the specific 10. General descriptions of berths, galley, etc., are still needed. The "plan vue d'ensemble" for the Biloup 10m might contain interior layout, but I cannot interpret images.
  • Anecdotal handling descriptions: "Good performer" and "reasonably stable/stiff" are general. More specific nuances of how it handles in various conditions would be beneficial.
  • Owner's Perspectives: While the search for owner reviews yielded some forum results, they are mostly general comments about smaller Bi-Loups or about the brand's history, not specific strengths or weaknesses of the Bi-Loup 10 from owner feedback. One result mentions owners not wanting to change boats for 10-15 years, suggesting satisfaction.

Given the limitations, I will focus on the information I have and avoid fabricating details for sections where information is sparse. I will explicitly state when information is general to the builder or type rather than the specific model.

I will attempt another search specifically for "Bi-Loup 10 interior details" and "Bi-Loup 10 sailing review" to try and get more specific anecdotal handling.
