About the Seaward 46Rk Sailboat

Nick Hake's design philosophy shines through in this distinctive lifting keel cruiser from Seaward Yachts. Built from 2012 onward, the 46RK represents an innovative approach to bluewater sailing with its unique lifting keel configuration and dual rudder setup, offering the rare combination of shallow water accessibility and deep water performance. The lifting keel system allows adventurous cruisers to explore skinny waters and remote anchorages typically off-limits to traditional deep-draft vessels, while maintaining the stability and seaworthiness expected from a 23,000-pound displacement cruiser. With 7,500 pounds of ballast and a comfort ratio of 24.86, this boat prioritizes motion comfort over pure speed, making it ideal for extended offshore passages and coastal exploration. The masthead sloop rig with 1,006 square feet of sail area provides balanced performance across varying wind conditions, while the dual rudder configuration enhances control and reduces weather helm. At nearly 49 feet overall with a 13.25-foot beam, the 46RK offers spacious accommodations without sacrificing seaworthiness. The low capsize screening value of 1.87 confirms its offshore credentials, making it a compelling choice for serious cruising couples seeking global adventure with the flexibility to venture into challenging waters.
