Raymarine Wireless Vertical Wind Transmitter

The Raymarine Wireless Vertical Wind Transmitter (model T222) is a mast-mounted anemometer designed to deliver accurate true wind speed (TWS) and true wind angle (TWA) data to compatible Micronet-based marine navigation systems. The 1.35-meter (4 feet 5 inches) vertical mast elevation positions the wind sensor above deck-level turbulence, reducing the aerodynamic interference that disturbs airflow around the mast and dramatically minimizes upwash error during downwind sailing—a critical advantage for performance-sensitive navigation and tactical weather assessment in marine operations.

The unit employs wireless transmission to eliminate the cable runs and physical deck penetrations associated with wired wind sensors, simplifying installation and reducing maintenance points. The T222 can be fitted while the mast remains in place, allowing retrofit installation without mast strikes or extended downtime. Calibration integrates directly with any Micronet display unit, enabling quick verification and adjustment without specialized tools or external calibration equipment. The transmitter's design prioritizes sensor isolation—the extended vertical separation between the sensor head and mast structure is engineered to minimize the wind shadow effect that compromises accuracy on conventional deck-level installations.

This system serves maritime professionals, racing crews, commercial vessel operators, and tactical watercraft personnel who depend on high-confidence wind data for navigation, tactical positioning, and performance optimization. Accurate wind measurement is essential for offshore operations, where real-time environmental awareness directly impacts tactical decision-making and vessel safety. The Raymarine T222 addresses the fundamental limitation of mast-proximate wind sensors: systematic measurement error caused by aerodynamic distortion.

Raymarine is recognized in marine electronics for precision navigation and environmental sensing systems. The T222 Vertical Wind Transmitter represents the midrange solution between basic deck-level anemometers and full masthead-mounted sensor packages, offering the accuracy advantage of elevated sensing without the structural and installation complexity of integrated mast-top systems. Users operating in salt-air environments benefit from the wireless architecture, which eliminates corrosion-prone connector interfaces typical of hardwired installations.
