Over the past ten years, I’ve interviewed Jack Sarin about a number of his designs, including several of the 20-some yachts his firm, Jack Sarin Naval Architects, created for Crescent between 1983 and 2001. While the years have changed, the character of the conversations has not: He speaks frankly, even bluntly, whether it’s to explain his firm’s role in the evolution of a design or to dispel potentially misleading information. (One of my favorite statements, in response to me double-checking information a marketing representative once supplied: “Never ask a salesman a technical question!”)

Given his firm’s history with Crescent, it was no surprise the yard tapped him when it decided to bring hull construction in house—and the straightforward explanation he gave me regarding the design was no surprise, either. He says his firm was asked to conceive a new variable beam/length design “which would combine the best characteristics of all our past hull designs with any up-to-date hydrodynamic advancements for Crescent’s future in-house production.” Specifically, he says, it was intended to accommodate yachts from 107 to 130 feet in length and from 24'6" to 27'6" in beam, with a relatively horizontal sheer aft.

As for the “hydrodynamic advancements,” Sarin further explains that a scale model was tank-tested at B.C. Research in Vancouver, Canada, in the summer of 2001.(B.C. Research, at the University of British Columbia, is one of the main testing facilities that production and custom yards turn to for expert evaluation.) Close attention was paid to the tunnels’ design, the angle of entry, and the trim angle under various load conditions and sea states. “The objective is to produce a clean bow wave with the least side-wetting and to establish the best possible running angle and laminar flow to ensure the least resistance,” he says. “The desired end result is...the ‘next generation’ of hull design.” Then, in typical Sarin fashion, he adds, “Is this rocket science? No, but the performance is predictable and is well worth the cost, a small percentage of the overall cost of the vessel.”           —D.M.B.
