Equip your vessel with reliable wind data that sailors trust on open waters. This masthead wind vane transducer delivers precise readings of apparent wind speed and direction, straight from the top of your mast. Pair it with boat speed and heading sensors to unlock true wind calculations, helping you trim sails perfectly or navigate powerboats with confidence. Designed for everyday cruisers and weekend warriors, its compact arm keeps it clear of sail turbulence while maintaining top-notch accuracy in breezy conditions.
Built to withstand harsh marine environments, this unit combines rugged anodized aluminum with UV-resistant plastics, ensuring it holds up against salt spray, relentless sun, and pounding winds. Unlike bulkier alternatives, its streamlined 14.5-inch arm positions the vane and cups optimally for clean airflow, reducing errors from mast shadows or heel-induced disturbances. Sailors report consistent performance from light zephyrs to gusts over 40 knots, making it a staple for regattas, coastal hops, or offshore passages.
This transducer plugs right into popular Raymarine displays, feeding data to dashboards that calculate advanced metrics like velocity made good or laylines. It's a drop-in upgrade for older setups, breathing new life into legacy cockpits without rewiring headaches.
Note: For ST70 setups, ensure you have the dedicated wind pod for full functionality.
Mounting at the masthead maximizes exposure to undisturbed wind. Align the vane forward during calibration for spot-on zeroing. Secure the base with marine-grade fasteners, routing the cable inside the mast to avoid chafe. Test in varied winds post-install to verify smooth rotation—free-spinning cups are key to reliable data. This setup shines on monohulls under 50 feet, where proximity to sails demands precision without long-arm complexity.
In cruiser tests, it nails 1-degree direction resolution and speed accuracy within 2% up to 60 knots. The feather-cone cups slice through gusts, while the balanced vane tracks shifts instantly—crucial for spinnaker sets or tacking duels. Powerboaters appreciate heel-compensated data for autopilot tweaks. Over years of exposure, its corrosion-resistant finish keeps readings crisp, outlasting plastic-heavy competitors.
Rinse with fresh water after every sail to flush salt. Inspect bearings annually; lubricate sparingly with silicone grease. Replace cups or vanes proactively if pitting appears—kits are straightforward. Store spares aboard for remote fixes, ensuring uninterrupted wind wisdom voyage after voyage.
Its short 14.5-inch arm excels in typical cruiser wind patterns, staying clear of sail wash while delivering accurate apparent wind data without the fragility of longer versions.
Yes, it's fully compatible with ST60+ series, providing direct plug-and-play wind speed and angle readings to your display.
It comes with a 30-meter (about 100 feet) cable, ideal for most mast heights and cockpit runs.
Absolutely—both feature quick-release designs for on-the-water repairs, extending the unit's service life.
It measures apparent wind; true wind requires integration with speed log and compass data via compatible instruments.
Anodized aluminum body paired with UV-stabilized plastics resists corrosion and fading in marine conditions.
The wired masthead wind transducer provides accurate measurement of relative wind speed and direction. When combined with other sensors like boat speed and compass, the masthead transducer provides the necessary wind information to calculate true wind speed, true direction and many other advanced data items. Available in 2 different lengths, the 300 Millimeter short-arm version is the perfect choice for cruising sailboats or power boats. High performance sailing boats may prefer the 600 Millimeter long-arm version which moves the transducer farther away from the updraft of the boat's sails for enhanced accuracy.
