B&G 213 Wind Sensor/Masthead Unit

Enhance your sailing experience with the precision and reliability of the B&G 213 Masthead Unit, a cornerstone for any performance-oriented navigator. Designed for the demands of offshore racing and cruising, this sensor delivers accurate wind data straight from the masthead, helping skippers make split-second decisions on sail trim, tacking angles, and course adjustments. Unlike basic transducers, the 213 stands out with its proven track record in extreme conditions, from Force 10 gales to balmy trade winds.

Precision Wind Data for Competitive Edge

At the heart of the B&G 213 is its ability to capture true wind speed and apparent wind angle with exceptional accuracy. The 3-cup anemometer spins smoothly to measure speed via pulse output, while the vane provides precise directional data through analogue signals. This raw data feeds directly into your instrument system, enabling advanced processing for true wind, velocity made good (VMG), and laylines—essentials for winning races or safely navigating tricky waters.

Sailors rave about its responsiveness during maneuvers; gusts register instantly, allowing proactive reefing or headsail changes. In my experience reviewing marine electronics, units like this separate casual cruisers from podium finishers in events like the Sydney Hobart or Fastnet Race.

Built to Withstand the Elements

Constructed from corrosion-resistant materials, the 213 thrives in saltwater spray, UV exposure, and howling winds. Its rugged housing protects sensitive components, ensuring longevity without frequent replacements. Fully field-serviceable design means you can replace cups, vane, or bearings on the water using basic tools—no need for a full mast climb or dealer service. This self-reliance is a game-changer for bluewater voyages where spares are your lifeline.

Seamless Integration with Legacy Systems

Perfectly tuned for B&G's H5000 and H3000 series processors, the 213 outputs clean pulse and analogue signals for plug-and-play compatibility. It shines in multi-instrument setups, feeding data to chartplotters, autopilots, and tactical displays. For upgrades, it pairs effortlessly with modern Hercules networks, breathing new life into older boats without a complete refit.

Practical Installation Insights

Mounting is straightforward on standard masthead brackets—align the unit north during calibration for spot-on readings. Opt for low-friction guy wires to minimize interference, and position it above any stack to avoid disturbed airflow. Regular freshwater rinses post-sail prevent salt buildup, extending service intervals. Pro tip: During annual checks, lubricate bearings lightly to maintain that whisper-quiet operation even at 50+ knots.

Why Serious Sailors Choose the 213

Beyond specs, the 213 embodies B&G's heritage in wind instrumentation. It's not just a sensor; it's a trusted partner that logs thousands of miles on grand prix racers and family cruisers alike. Skip the guesswork of erratic readings—invest in data you can rely on when it counts most.
