B&G Wind Speed Cups f/All Models

Keep your sailing instruments performing at their peak with these precision-engineered wind speed cups designed specifically for B&G masthead units. Sailors know that accurate wind data is the heartbeat of tactical decisions on the water—whether you're racing around buoys or cruising long distances. These replacement cups ensure your wind sensor delivers reliable readings, even in harsh marine environments where salt spray, UV exposure, and constant rotation can wear down components over time.

Why Choose Genuine B&G Wind Speed Cups?

Unlike generic alternatives, these cups are crafted from durable, weather-resistant materials that match the exact specifications of your B&G wind sensor. They feature a lightweight, aerodynamic design that minimizes drag while maximizing sensitivity to subtle wind shifts. The included mounting nut simplifies swaps, getting you back on the water faster without specialized tools. Regular replacement prevents data inaccuracies that could cost you precious seconds in a race or compromise safety in gusty conditions.

Perfect Compatibility Across B&G Models

These wind speed cups fit seamlessly with all B&G wind sensor models, making them a go-to spare for fleet owners, charter operators, and weekend warriors alike. From compact racing setups to full-featured cruising systems, they integrate without modifications. Pair them with your existing anemometer body for consistent performance that syncs perfectly with B&G displays, autopilots, and NMEA 2000 networks.

Key Specifications at a Glance

• Direct replacement for all B&G wind sensor models
• Precision-balanced for accurate speed measurement
• UV-stabilized cups resist fading and cracking
• Corrosion-resistant construction for saltwater longevity
• Complete with stainless steel mounting nut

Easy Installation for On-the-Water Maintenance

Swapping out worn cups is straightforward, even at the dock or anchorage. Here's a quick sailor-approved process:

1. Secure your masthead safely—use a bosun's chair or steady ladder.
2. Remove the old cups by loosening the mounting nut (typically counterclockwise).
3. Align the new cups with the anemometer shaft markings for proper orientation.
4. Tighten the nut firmly but avoid over-torquing to prevent thread damage.
5. Spin-test by hand to ensure smooth rotation, then calibrate your system if needed.

Pro tip: Inspect bearings during replacement; a drop of marine-grade lubricant keeps everything spinning freely.

Extend the Life of Your Wind Sensor

Investing in quality spares like these pays dividends in reliability. Wind cups are the first to show wear from bird strikes, debris, or prolonged exposure, but proactive replacement maintains the three-cup configuration proven for low-friction, high-resolution data. Combine with regular masthead rinses using fresh water to flush salt buildup, and your setup will outlast the competition.

Real-World Performance from Fellow Sailors

Offshore racers report crisper apparent wind angles during tacks, while cruisers appreciate consistent true wind speeds for optimal sail trim in varying conditions. These cups restore factory-fresh accuracy, helping you trust your instruments when it matters most—from clipping the windward mark to navigating squalls.
