Feathercraft kayaks are renowned for having the most comfortable seats you'll find in a kayak. A foam cushion with a molded seat bottom and inflatable lumbar support rest on a fabric sling, suspended from the kayak's frame. The built-in coaming system simplifies assembly, and still allows the use of a standard spray skirt and individual sea sock. Nylon spray skirts and sea socks are made from high tenacity 420 denier urethane coated packcloth and seam taped. Sponsons are air tubes welded from supported urethane, and are inside the skin on each side of our sit-in models. Four large sponsons create the platform of our sit-on-top models. Each sponson is inside a protective fabric sleeve and is easily removed for repair or replacement. When not included as standard, a sturdy, easy to use rudder is an available option. And to wrap it all together, the welded Polytech deck with Duratek hull is our revolutionary Sealskin technology that keeps the water out!
