Built between 1970 and 1974, the Swan 37 succeeded the Swan 36 Tarantella and carried design number 2035 from the New York firm. Production totaled just 59 examples.
Design and Construction
Sparkman & Stephens drew the Swan 37 as the successor to the best-selling Swan 36 Tarantella. The connection is particularly clear in the tall, square deckhouse, which sits well forward of the mast and is reminiscent of the earlier boat.
The fiberglass hull is rather narrow fore and aft but wide amidships, with a maximum beam of 3.25 m. Important bow sections combine with a very narrow stern that sits high on the water. Its counter lines dip only as wind and speed build.
The boat’s appearance reflects the RORC-era regatta rules then in force. Its most distinctive construction feature is a special trim tab at the rudder—an adjustable appendage “tail” that S&S had already used on the America’s Cup winner Intrepid.
Rig, Machinery, and Performance
The Swan 37 is a masthead sloop with an “I” measurement of 46.25 feet and a “J” of 15.6 feet. The mainsail measures roughly 237 square feet, while the 150% genoa exceeds 541 square feet. A 1,299-square-foot spinnaker further reflects the design’s offshore-racing intent.
A 25-horsepower Volvo Penta MD2B, turning at 2,500 rpm, powers the boat. Displacement is 15,400 pounds, backed by 7,300 pounds of lead ballast.
The Swan 37 distinguished herself with particularly strong performance, winning numerous races, including ocean events. Her narrow, high stern and rudder trim tab mark her as a boat shaped for speed rather than interior volume. Reduced cabin space at the narrow ends is the price of that racing-derived waterline.
Accommodations
Below, the cozy, very warm dinette amidships forms the social and visual center of the boat. The narrow ends and beam-forward hull leave somewhat less cabin volume forward and aft. As a result, the Swan 37 has a warm central saloon surrounded by more utilitarian sleeping and stowage spaces, rather than the evenly distributed room of a more uniformly spacious cruiser.
The deckhouse geometry inherited from the Tarantella reinforces this midship-focused arrangement.
History and Market Identity
Production began with the 1970 launch and continued through 1974. Production totaled 59 hulls, and approximately sixty boats are still around.
Other shipyards also executed the design in the United States, where examples can be found under the Palmer&Johnson 37 name. That name appears only domestically.
Given its age and limited production, the Swan 37 remains a quietly collected boat among knowledgeable owners rather than a common brokerage listing.
The Verdict
The Swan 37 is a slender, well-bred S&S racer-cruiser. Its rudder trim tab and ocean-racing record point to a serious design lineage, while the warm midship dinette and Tarantella-derived deckhouse provide a livable core.
The narrow ends and reduced forward and aft volume are the cost of its performance-oriented hull. With only 59 boats built, anyone looking for a Swan 37 is searching for something scarce and highly specific.
Pros
- S&S racing-derived hull with an America’s Cup-informed rudder trim tab
- Strong period performance record, including ocean races
- Warm central dinette and recognizable S&S deckhouse character
- Scarce 59-boat series with lasting appeal among connoisseurs
Cons
- Narrow, high stern and slim ends reduce forward and aft cabin volume
- Beam well below modern 37-foot norms limits interior spread
- Very limited production can make finding one a slow search
