About the BI-LOUP 77
Optional engine to 15hp.
The Bi-Loup 77 is a compact, trailerable sloop designed by Wrighton and built by Wrighton Yachts in France between 1985 and 1995, with a total production of 100 hulls. Its lightweight displacement of 3527.0 lb and shallow draft of 2.79 ft define its role as a nimble, easy-to-handle day sailor or coastal cruiser.
- Best for:
- This boat is ideally suited for single-handers or couples seeking a low-maintenance, trailerable package for coastal cruising and day sailing. Its manageable size and shallow draft make it excellent for exploring protected waters and launching from small ramps.
- Bluewater capability:
- With a low displacement of 3527.0 lb and a capsize ratio of 2.16, the Bi-Loup 77 is not designed for extended bluewater passages but is capable of short offshore trips in moderate conditions.
- Comparables:
- Comparable vessels include other Wrighton designs like the Bi-Loup 66 or 88, as well as contemporary trailerable sloops such as the O'Day 23 or Catalina 22. These boats share similar dimensions, trailerability, and a focus on ease of handling over high-performance racing.
