About the EXTENSION 24
The Extension 24 is a compact, performance-oriented fractional sloop designed by Jac de Ridder and built by George Stead Yachts (UK) in 1974. With a displacement of 2006.0 lb and a low comfort ratio of 7.72, this vessel represents a lightweight, planing-capable design from the mid-1970s.
- Best for:
- This boat is best suited for coastal cruising and daysailing, appealing to sailors who prioritize speed and agility over heavy offshore comfort. Its light displacement and fractional rig make it an excellent candidate for single-handers or couples seeking a responsive, easy-to-handle package.
- Bluewater capability:
- With a capsize ratio of 2.88 and a displacement of 2006.0 lb, the Extension 24 is not recommended for serious bluewater passagemaking due to its light weight and low stability margins in heavy weather.
- Comparables:
- Comparable vessels include other lightweight, performance-oriented 24-footers from the 1970s such as the O'Day 24 or Pearson 24, though the Extension 24 distinguishes itself with a more modern, narrow-beam hull form and fractional rig. It shares DNA with other Jac de Ridder designs of the era that emphasize sail plan efficiency over heavy displacement.
