The Westerly GK 34 represents a distinct departure from the traditional, heavy-displacement cruising identity often associated with the Westerly name. Launched in the late 1970s and designed by the renowned Ed Dubois, the GK 34 was conceived as a high-performance Three-Quarter Tonner, built to compete under the International Offshore Rule (IOR). The "GK" prefix, standing for "Great Knight" (or more colloquially, "Giant Killer"), signaled the builder's intent to push into the elite racing circuit. While most of the 19 units produced were constructed of traditional glass-reinforced plastic (GRP), the model’s pedigree for innovation was cemented by the production of two "Grand Prix" variants featuring advanced Kevlar hulls—a rare and high-tech approach for the era. The boat successfully balanced the rigid requirements of a competitive racer with an interior that, while functional for a crew, offered enough refinement for fast coastal cruising.
