About the AQUARIUS 40 (S&S)
See S&S 40(1964). A later version of S&S design #1767.
The Aquarius 40 is a rare, heavy-displacement cruiser designed by Sparkman & Stephens and built by Turun Teräskaluste in Finland between 1974 and 1976. With only 5 hulls built, this vessel represents a highly exclusive segment of the market, characterized by its robust construction and traditional design ethos.
- Best for:
- This boat suits experienced cruisers seeking a quiet, stable, and well-built vessel for coastal and near-offshore passages who value rarity and classic S&S design over high-performance sailing.
- Bluewater capability:
- With a displacement of 17200.0 lb and a capsize ratio of 1.55, the Aquarius 40 exhibits strong offshore stability and seakeeping ability, making it well-suited for bluewater cruising despite its limited production run.
- Comparables:
- Comparable boats include other Sparkman & Stephens designs from the 1970s such as the Cal 40 or O'Day 40, which share similar heavy-displacement characteristics and masthead sloop rigs, though the Aquarius 40 is distinguished by its Finnish steel construction.
