Seamaster Polyurethane Boat Steering Wheel – 320 mm (Aluminum Spokes)

This 320 mm Seamaster polyurethane steering wheel is designed to enhance handling and comfort on small to mid-sized boats. With a diameter of 320 mm, the wheel is slightly more compact than the standard 350 mm, making it an excellent choice for tight cockpit spaces or for boats where a quicker steering response is desired.

Design & Material: The wheel’s rim is made from a solid polyurethane with a soft-touch coating – it provides a secure grip even with wet hands or gloves. Polyurethane is known for not cracking or degrading under sun exposure, and it also absorbs some of the vibration from the engine or chop, reducing helm fatigue. Inside the rim is a metal reinforcement band that prevents any flexing of the wheel under load.

The spokes are crafted from marine-grade aluminum, which offers both light weight and strength. There are three spokes extending to the hub – this classic three-spoke design leaves open sight lines to your gauges, ensuring you can easily read instruments on the dash. The aluminum is anodized or coated to resist corrosion, and the overall finish of the wheel is a stylish black “carbon fiber” effect – the rim and center cap have a carbon-fiber-like texture, giving your helm a sporty, modern flair.

Hub & Compatibility: The center hub is a standard 3/4" taper (19 mm), meaning it will fit directly onto most marine steering systems on the market (Ultraflex, Teleflex, etc.). If your boat has the typical splined or tapered steering shaft, installation is straightforward – just remove your old wheel and mount the Seamaster wheel onto the shaft, securing it with the retaining nut. The wheel comes with a decorative center cap that snaps on to cover the nut, providing a clean, finished appearance.

Operational Benefits:

• Comfortable Steering: The soft polyurethane rim is easy on the hands – even during long periods at the helm or in rough seas, you won’t experience the discomfort or slippage that can come with hard plastic wheels. The material stays relatively cool in the sun and won’t chill your hands in cold weather.
• Excellent Control: The 320 mm diameter allows for quicker lock-to-lock turns, which is valuable when maneuvering in tight quarters or during sporty driving. At the same time, it still offers enough leverage for precise control at higher speeds. The slightly smaller wheel often means you can steer with less hand-over-hand motion, making steering feel more responsive.
• Rugged Marine-Grade Build: The wheel weighs about 1.3 kg – an indicator of the density of the materials. This weight contributes to a steady, solid feel. There is no “give” in the spokes or flex in the rim, which can be an issue with cheaper, hollow plastic wheels. The Seamaster wheel can withstand the vibrations from an outboard engine and the shocks from waves without any structural issues.
• Long Lifespan & Easy Maintenance: All components are resistant to saltwater and UV rays. The polyurethane won’t fade or chalk, and the aluminum parts won’t rust. Maintenance is as simple as rinsing with fresh water after use in saltwater and an occasional wipe down – the materials require no special treatments.
• Aesthetics: The black wheel with subtle carbon-fiber accents gives your console a modern look. It complements both classic white hull interiors and darker or colored dashboards, adding a touch of sportiness to your boat’s style. It looks as good as it feels, upgrading the helm’s appearance along with its functionality.

Recommended Use: The Seamaster 320 mm wheel is suitable for a wide range of vessels – from small fishing boats and RIBs to sport boats and even jet boats with console steering. For boats in the roughly 4 to 6 meter range, this size offers an excellent balance of fine control and quick response. If you’re looking to replace an old wheel with something reliable and comfortable, this model will increase your enjoyment at the helm and serve you faithfully for many seasons to come.
