This universal steering wheel knob (spinner) with a 58 mm diameter is a practical accessory that greatly simplifies boat handling. It attaches securely to the wheel’s rim via an adjustable clamp, compatible with rim diameters between 28 and 32 mm – a range that covers most standard marine wheels. Once installed, the knob enables easy one-handed turning of the wheel, which is especially useful in situations requiring quick and precise maneuvers.
Made of high-strength plastic with metal components, this knob is built to withstand harsh marine conditions, including intense sun, saltwater, and continuous use. It’s commonly employed by skippers of larger yachts and cruisers, where wheel diameter and steering effort are greater. With this spinner knob, you can confidently maneuver during docking or when navigating narrow channels, maintaining full control of the vessel with less effort. Installation is quick and requires no special tools – place the bracket around the wheel, tighten the knob with the provided screws and nuts, and you’re ready for easier steering.
- Suitable for all types of boats and yachts – from small runabouts to large cruisers – where improved maneuverability is an advantage.
- Valuable for sailboat helms (for quick tacking) or fishing boats (when navigating tight spots) as it provides faster wheel response.
- Allows one-handed steering, keeping your other hand free (for throttle control, radio, etc.).
- Easily removable or transferable to another wheel if needed.
- Enhances safety – quicker turn response helps avoid obstacles and enables more precise docking.
