Schock 40 Information, Review, Specs

The Schock 40 began production in 2000, with only ten units ultimately built, marking it as a relatively rare and specialized vessel. The boat's genesis was rooted in the innovative Canting Ballast Twin Foil (CBTF) system, patented by DynaYacht and refined on a prototype named "Red Hornet." This system was engineered to dramatically reduce the amount of ballast typically required for a boat of its size, reportedly by up to 50%, by allowing the keel to cant, effectively generating more righting moment and enhancing performance. This design philosophy was driven by a goal for "all-out performance" in a "team-oriented raceboat."

W.D. Schock Corporation, the builder, has a long-standing reputation for crafting quality fiberglass yachts with a focus on forward-thinking design and craftsmanship. From its founding by William "Bill" D. Schock, the company specialized in fiberglass sailboats, and the Schock 40 continued this tradition of innovation in construction. While no significant production variations like MkI or MkII models are noted, the core identity of the Schock 40 is intrinsically linked to its unique canting ballast and twin foil configuration, which set it apart from conventional designs.

Sailing Performance and Handling

The Schock 40's design ratios underscore its radical performance orientation. With a calculated Sail Area to Displacement (SA/D) ratio of approximately 29.5, the Schock 40 boasts an exceptionally high figure, indicating that it is designed for spirited performance, particularly excelling in lighter wind conditions. Its Displacement to Length (D/L) ratio, at roughly 72.88, is remarkably low, classifying it as an ultra-light displacement vessel, which translates to superior speed potential and agility on the racecourse.

The Ballast to Displacement ratio stands at about 0.257, which would typically suggest lower stiffness and stability in a conventional keel boat. However, this seemingly low figure is profoundly offset by the revolutionary Canting Ballast Twin Foil (CBTF) system, which allows the keel to pivot, dynamically increasing the boat's righting moment as needed. This technological advancement effectively compensates for the reduced fixed ballast, allowing the boat to stand up to more wind and carry its substantial sail plan efficiently. Anecdotal accounts from sailors describe the Schock 40 as "shockingly easy and fun" to sail, suggesting that its advanced systems contribute to a manageable and enjoyable, albeit high-performance, experience. A review in Sailing World also highlighted its suitability as a sportboat emphasizing "all-out performance".

Accommodations and Layout

The interior of the Schock 40 reflects its primary purpose as a high-performance racer, featuring a minimalist layout rather than extensive cruising amenities. Despite this, it offers functional accommodations designed for a racing crew. Available information suggests a layout with "stand-up headroom" and sufficient "sleeping accommodation" for overnight use. While detailed specifications on interior finishes are limited, the focus would likely have been on weight savings and functional, durable materials, consistent with its racing pedigree. The boat is equipped with a modest 12-gallon fresh water capacity. Online resources, including owner-produced videos, offer glimpses into the interior arrangement, showcasing the practical use of space.

Owner's Perspectives

Owners and enthusiasts generally discuss the Schock 40 in the context of its groundbreaking technology and performance. It is frequently praised for its high-performance capabilities and the unique sailing experience provided by the CBTF system, with some owners describing it as "shockingly easy and fun" to sail, even in challenging offshore conditions.

However, as with any pioneering technology, the Schock 40 has faced some challenges. Discussions among owners and in sailing forums occasionally highlight "issues" related to its "rigs, chainplates and of course the canting keels." Some "teething problems" with the innovative canting keels were noted, and there was at least one documented instance of a keel detaching from a Schock 40 in 2000. These discussions underscore the cutting-edge nature of the design and the complexities sometimes associated with early adoption of new marine technologies. Despite these considerations, the boat continues to generate interest in performance sailing circles, with owners keen to understand and manage its unique characteristics.
