Raymarine Replacement Wind Cup Set f/Anemometer

Keep your vessel's wind readings precise and reliable with this essential replacement set designed specifically for marine anemometers. Over time, exposure to harsh saltwater environments, high winds, and UV rays can wear down wind cups, leading to inaccurate speed measurements that affect everything from sail trim to safe navigation. This replacement kit restores factory-level performance, ensuring you capture true wind data whether you're racing offshore or cruising coastal waters.

Crafted from durable, weather-resistant materials, these cups spin smoothly to deliver consistent readings even in gusty conditions. Sailors and powerboaters alike trust this upgrade to maintain the integrity of their onboard weather station without the need for full instrument replacement.

Key Features and Benefits

• Precision Engineering: Three-cup design optimized for low-friction rotation, providing accurate wind speed from light breezes to gale-force winds.
• Corrosion-Resistant Build: UV-stabilized polycarbonate construction withstands prolonged sun exposure and salty air, extending service life on deck.
• Easy Snap-On Fit: Direct replacement that installs in minutes, minimizing downtime during maintenance stops.
• Balanced Performance: Ensures minimal vibration and noise, protecting sensitive anemometer bearings for long-term reliability.
• Enhanced Safety: Reliable data supports better decision-making, from reefing sails early to plotting optimal routes around weather fronts.

Perfect Compatibility for Seamless Upgrades

This set integrates flawlessly with popular marine wind systems, making it a go-to choice for refits. It pairs with legacy and modern setups, supporting displays that rely on precise anemometer input for apparent and true wind calculations. Ideal for boats equipped with compact wind transducers mounted on mastheads or at deck level.

Simple Installation Steps

1. Power down and secure your anemometer to prevent accidental spins.
2. Gently remove the old cups by twisting or releasing the retaining clip—inspect the hub for debris and clean if needed.
3. Align the new cups with the drive shaft markings for proper phasing.
4. Snap or press-fit securely, then test-rotate by hand to confirm smooth, even motion.
5. Re-energize the system and calibrate via your display unit for peak accuracy.

Pro tip: Perform this swap during a calm anchorage or haul-out to avoid wrestling with tools aloft in choppy seas.

Maintenance Tips for Lasting Performance

To maximize longevity, rinse cups regularly with fresh water after exposure to spray. Inspect annually for cracks or imbalance, especially before long passages. A quick freshwater spin test can reveal early wear—replace proactively to sidestep data glitches mid-voyage. Pair with anemometer lubricant sparingly if bearings feel sticky, but avoid over-application to prevent saltwater attraction.

Why Mariners Rely on This Replacement

In the demanding world of boating, skimping on wind gear isn't an option. Worn cups skew not just speed but direction data too, throwing off autopilot tacks and wind-shift predictions. This genuine-spec set brings back that crisp responsiveness, letting you focus on the horizon rather than troubleshooting. Whether upgrading a classic setup or refreshing after storm season, it's the smart, cost-effective path to trusted wind intelligence.
