About the DUET 25
Variation of the Nordic Folkboat but with a separate fin keel. Thorkild Lind was a well known boat builder. His own 'Tibbe' was used to create a mold from which a number of glassfibre Nordic Folkboats were built. Shoal Draft vers. draws 4.2'.
The Duet 25 is a compact fractional sloop designed and built by Thorkild Lind, with production records indicating a build year of 1974 and an unknown total hull count. With a displacement of 3600.0 lb and a beam of 8.4 ft, this vessel represents a specific era of small-craft design that prioritizes manageable dimensions for trailerability and coastal cruising.
- Best for:
- This boat is best suited for coastal cruisers and weekend warriors who prioritize trailerability and ease of single-handed handling over long-range offshore performance. Its light displacement and modest sail area make it ideal for protected waters and short passages where quick setup and transport are key.
- Bluewater capability:
- With a low displacement of 3600.0 lb and a capsize ratio of 2.2, the Duet 25 is not recommended for serious bluewater cruising due to its light weight and limited reserve buoyancy for heavy weather.
- Comparables:
- Comparable boats from this era include the O'Day 23 and the Pearson 23, which share similar fractional sloop rigs and trailerable footprints. These vessels are comparable because they target the same market of entry-level sailors seeking affordable, manageable boats for bay and coastal sailing.
