The Spinlock Joystick Tiller Extension is designed to enhance the experience of steering in tough conditions while reducing strain. The EJ Tiller Extension features a compact, straight-handled racket grip, and can be easily upgraded to an Asymetric handle or vice versa. The included Diabolo version is often preferred by single-handed yachtsmen, and is commonly used in boats that are steered by autopilot. Available in four standard lengths, the tiller extension offers a variety of options to suit different cockpit sizes and needs.
