About the DUFOUR T6
The Dufour T6 is a compact 20.18 ft fractional sloop designed by Laurent Cordelle and built by Dufour (FRA) in 1981. With a displacement of 1764.0 lb and a beam of 7.87 ft, this vessel represents a lightweight, performance-oriented entry-level cruiser from the early 1980s.
- Best for:
- This boat is best suited for coastal day-sailing and weekend cruising, particularly for single-handers or couples seeking a manageable, trailerable package with easy handling characteristics.
- Bluewater capability:
- With a low comfort ratio of 9.7 and a capsize ratio of 2.61, the T6 is designed for protected waters and is not recommended for offshore or bluewater passages due to its light displacement and narrow beam.
- Comparables:
- Comparable boats include the Benetele First 20 and the O'Day 20, as they share similar fractional sloop rigs, lightweight displacement profiles, and target the same market of novice sailors and coastal cruisers.
