The genesis of the Gulfstream 42 traces back to 1960, marking its entry into the sailing world as Sparkman & Stephens design #1624. Robert E. Derecktor Inc., the esteemed builder, commenced its construction, with at least three units confirmed to have been built, and some reports suggesting up to six. During this era, Derecktor Shipyards had already established a formidable reputation for constructing strong, well-made vessels characterized by a fine finish, a philosophy that undoubtedly influenced the Gulfstream 42. The company was known for its adaptability in using various materials, and the Gulfstream 42 exemplifies this by featuring an aluminum hull and deck, a testament to Derecktor's evolving capabilities and commitment to quality. Sparkman & Stephens, celebrated for their impactful designs, ensured the Gulfstream 42 carried the pedigree of a yacht designed for performance and reliability. Notably, the Gulfstream 42 was offered with versatility in rigging, available to owners as either a sloop or a yawl configuration.

Sailing Performance and Handling

With a reported sail area of 784 square feet and a displacement of 18,445 pounds, the Gulfstream 42 boasts a Sail Area to Displacement ratio of approximately 17.95. This figure suggests a boat that is responsive in lighter winds but not an extreme light-air performer, offering a balanced sailing experience. Its ballast-to-displacement ratio of around 38% indicates a good degree of stability, allowing it to stand up to a respectable amount of wind without excessive heeling. This contributes to its reputation as a stable and stiff vessel with excellent righting capability.

Further emphasizing its robust nature, the Displacement to Length ratio of approximately 328.39 positions the Gulfstream 42 firmly in the category of a heavy, traditional cruiser. This heavy displacement, combined with a 29.25-foot waterline, contributes to a comfortable motion in a seaway, making it well-suited for extended voyages and offshore conditions. The boat is rigged as a masthead sloop, a configuration known for its simplicity and effectiveness, further reinforcing its design as a reliable cruiser. Owners and enthusiasts describe the Gulfstream 42 as a "good performer" for a heavy sailboat, excelling in stability and offering excellent righting characteristics, making it particularly suitable for more demanding sailing environments.

Accommodations and Layout

While specific detailed interior layouts for the Gulfstream 42 are not extensively documented in public records, its dimensions—an overall length of 41.51 feet and a generous beam of 11.0 feet—suggest ample living space below deck for a vessel of its era. With a substantial water capacity of 145 gallons and a fuel capacity of 95 gallons, the Gulfstream 42 was clearly designed with extended cruising in mind, providing significant autonomy for its crew. Typically, yachts of this size and vintage would feature a V-berth forward, a main salon with settees that convert to berths, a galley, and a navigation station. Given Derecktor's reputation for "fine finish" and quality construction, it is reasonable to infer that the interior would have reflected a high standard of craftsmanship, likely featuring durable materials and thoughtful joinery common in custom-built yachts of the period.
