About the AVANCE 40
S&S #2436. Fin keel version draft: 7.02'.
The Avance 40 is a robust, heavy-displacement cruiser designed by Sparkman & Stephens and built by AB Oja Batar in Finland in 1982. With a displacement of 19600.0 lb and a D/L ratio of 267.03, it represents a classic, seakworthy design intended for serious offshore passage-making rather than light coastal racing.
- Best for:
- This boat suits experienced bluewater cruisers and those seeking a stable, comfortable passage-maker who prioritize safety and seakeeping over high-speed performance. Its fractional sloop rig and heavy ballast ratio make it well-suited for single-handers or couples who value ease of handling in heavy weather.
- Bluewater capability:
- With a capsize ratio of 1.87 and a comfort ratio of 30.15, the Avance 40 is highly capable offshore, offering exceptional stability and motion comfort in heavy seas. Its full/long keel design and substantial ballast of 8420.2 lb provide reliable tracking and safety, making it a proven choice for extended ocean passages.
- Comparables:
- Comparable boats include the Tartan 40 and the Cal 40, as they share similar heavy-displacement characteristics, Sparkman & Stephens design heritage, and a focus on offshore durability. The Avance 40 distinguishes itself with its Finnish construction quality and slightly heavier displacement compared to many American contemporaries of the early 1980s.
