About the KNOCKABOUT 24 (S&S)
The KNOCKABOUT 24 is a version of the RAINBOW 24 (but without the cuddy/cabin,) originally built for the Annapolis Sailing School. The KNOCKABOUT was used for some years as a trainer for the US Naval Academy.
The Knockabout 24 is a classic 1962 Sparkman & Stephens design built by Tidewater Boats, representing a rare and lightweight entry into the 24-foot cruiser market. With a displacement of 2250.0 lb and a beam of 6.25 ft, it offers a distinct performance profile compared to heavier contemporaries, though the exact number of hulls built remains undocumented.
- Best for:
- This boat is best suited for coastal day-sailing and light cruising where trailering is a priority, appealing to owners who value the S&S pedigree and ease of handling over heavy offshore endurance.
- Bluewater capability:
- With a low displacement of 2250.0 lb and a capsize ratio of 1.91, the boat is not ideally suited for extended bluewater passages, performing best in protected coastal waters where its light weight aids performance.
- Comparables:
- It compares to other 1960s Sparkman & Stephens designs like the S&S 26 or the smaller S&S 19, sharing the designer's hallmark balance and finish, but differs significantly in weight and scale from heavier production cruisers of the same era like the Catalina 22.
