History and Design

The Seaward 46 RK, with "RK" denoting its signature Retractable Keel, was first introduced in 2012, showcasing Nick Hake's continued commitment to innovative boat design. As the primary designer and builder for Hake Yachts (the parent company of Seaward Yachts), Hake's philosophy for the 46 RK was to create a vessel that transcended the limitations of mass-production builders, offering an innovative variable-draft cruising experience. This design ethos built upon the success of earlier, smaller RK models like the 26RK and 32RK, extending the concept to a larger, more capable platform. Seaward Yachts has historically prioritized solid construction and the ability to access extremely shallow waters, a principle fully embodied in the 46 RK. The vessel's design, including its lifting rudders, directly reflects this goal, ensuring uncompromised navigation in diverse environments.

Sailing Performance and Handling

The Seaward 46 RK is engineered for both performance and stability, a blend achieved through thoughtful design and its unique retractable keel system. With a sail area to displacement ratio of approximately 19.9, the 46 RK is a relatively light-displacement vessel for its length, suggesting spirited performance, especially in lighter air. This is further supported by its displacement to length ratio of around 114, indicating a performance-oriented cruiser that is nimble and responsive.

Despite its lighter displacement, the boat maintains remarkable stability, largely due to its substantial ballast of 7,500 pounds which is positioned low at the keel's base when fully extended. While its ballast-to-displacement ratio sits at about 0.326, the deep draft of 7.0 feet with the keel down ensures excellent upwind performance and stiffness when sailing. The retractable keel itself can be configured in three different positions, allowing sailors to optimize performance or draft as conditions demand.

Equipped with a masthead sloop rig, the 46 RK benefits from a simpler sail plan that carries its sail area lower, contributing to reduced heeling moments. Dual rudders provide precise control and enhance maneuverability, particularly advantageous when navigating in shallow water or docking. Owners and reviewers describe the 46 RK as capable of offshore passages while excelling in the shallow coastal waters it was primarily designed for, sailing faster and more efficiently than many of its contemporaries. The vessel boasts a hull speed of 8.97 knots, indicative of its cruising capabilities.

Accommodations and Layout

The interior of the Seaward 46 RK is designed with comfort and livability in mind, suitable for extended cruising. The layout provides comfortable accommodations for four adults and can be cozy for up to six. The owner's cabin is typically located forward, offering a private and spacious retreat. While specific headroom details are not provided in the primary specifications, the overall design emphasizes a thoughtful and efficient use of space, characteristic of a high-quality cruiser.

A notable feature is the option for an interior pilot station, which allows the crew to remain warm and dry while navigating in inclement weather, a significant advantage for colder climates or long passages. The interior finishes generally reflect a distinctive and classic design with attention to detail in the arrangements. While the specific materials used might vary, Seaward Yachts is known for solid construction, suggesting a robust and well-appointed living space. The salon often includes a versatile table that can be lowered to form an additional double berth, maximizing sleeping capacity.
