The S&S Gulfstream 30 is a classic wooden masthead sloop, renowned as a capable and comfortable cruiser, particularly well-suited for weekend excursions and coastal sailing. Designed by the esteemed naval architects Sparkman & Stephens (S&S design #1147) and meticulously built by Robert E. Derecktor, Inc., this vessel embodies a blend of elegant lines and solid construction that defined a golden era of yacht building. With a length overall of just over 30 feet and a long waterline, she offers a balance of manageable size and respectable performance, making her a cherished choice for sailing enthusiasts who appreciate traditional craftsmanship.

The genesis of the Gulfstream 30 dates back to 1955, emerging from the design boards of Sparkman & Stephens as design #1147. Robert E. Derecktor, Inc., a shipyard celebrated for its commitment to building "strong, well-made vessels characterized by a fine finish," undertook the construction of these yachts. During this era, Derecktor Shipyards, founded by Robert "Bob" E. Derecktor in Mamaroneck, NY, was establishing its formidable reputation for crafting exceptional wooden yachts, including iconic America's Cup contenders. The Gulfstream 30 exemplifies this ethos, featuring an oak and mahogany hull with a sheathed plywood deck and housetop, along with varnished Sitka spruce spars and bronze fastenings, highlighting a dedication to durable, high-quality materials and construction techniques. The boat features a fin keel design.

Sailing Performance and Handling

The Gulfstream 30 is characterized as a "medium-weight cruiser" with a displacement-to-length ratio of approximately 312.78, indicating a boat designed for stability and comfortable motion rather than extreme light-displacement speed. With a total calculated sail area of 422.17 sq ft and a displacement of 7700 lbs, her sail area-to-displacement ratio is around 17.17. This suggests a reasonably good performer, capable of moving well in moderate to strong breezes, though perhaps not optimized for very light air. The boat's 3,000 lbs of lead ballast contributes to a ballast-to-displacement ratio of approximately 39%, providing good inherent stability and an excellent righting capability if capsized. Anecdotal accounts describe her as a "lovely sailing boat," noted for a "speedy hull design" despite her weight, and capable of a hull speed of 6.32 knots.

Accommodations and Layout

Despite her moderate length, the Gulfstream 30 is often praised for being "surprisingly spacious for a boat of its size" and "roomy below for weekend cruises." While specific detailed layouts can vary slightly among individual boats due to customizations over the years, the design typically accommodates four people. Owners generally find the interior well-suited for cruising, with sufficient space for overnight stays. The emphasis on wood construction, evident in her hull, likely extends to the interior, offering a warm and traditional yachting ambiance.
