Upgrade your sailing setup with the Raymarine T222 Vertical Wind Transmitter, a game-changer for capturing precise wind data right where it matters most—above the turbulence of the masthead. Traditional wind sensors often battle distorted airflow from the mast, leading to skewed true wind speed (TWS) and true wind angle (TWA) readings. This innovative 1.35m masthead unit elevates your sensor into undisturbed air, delivering the reliable data serious sailors demand for optimal performance, whether you’re racing or cruising.
Why Choose the T222 for Superior Wind Measurement?
Sailors know that even small inaccuracies in wind readings can throw off your strategy. The T222 tackles this head-on with its lightweight carbon fiber design, which keeps weight aloft to a minimum while ensuring durability against harsh marine conditions. By positioning the transmitter higher, it minimizes upwash errors—especially critical when running downwind—and cuts through wind shear for readings you can trust. Pair it with your Micronet displays for seamless wireless integration, and calibrate effortlessly from the cockpit without climbing the mast.
Key Advantages in Real-World Sailing
Cleaner Air Readings: Lifts the sensor 1.35m above the masthead, escaping the chaotic airflow that plagues conventional setups.
Performance Precision: Accurate TWS and TWA data empowers polar diagrams, velocity made good calculations, and tactical decisions.
Hassle-Free Installation: Mounts easily with the mast in place, no need for major rigging changes or downtime.
Extended Runtime: Up to 300 hours of operation on a single charge, perfect for long passages or regattas.
Robust Build: Carbon fiber construction resists corrosion and fatigue, built to withstand UV exposure, salt spray, and high winds.
Seamless Integration with Your Micronet System
The T222 shines within the Raymarine Micronet ecosystem, transmitting data wirelessly to compatible displays, multifunction units, or even mobile apps. No messy wiring runs—just quick pairing and you’re set. For racing teams, this means real-time wind shifts at your fingertips, helping trim sails perfectly and outmaneuver the fleet. Cruisers benefit too, with dependable data for safe passage planning in variable conditions.
Installation Tips for Peak Performance
Positioning is everything. Secure the included mast-top mount to ensure the unit aligns vertically, maximizing exposure to true wind flow. Once mounted, use any Micronet display for straightforward calibration—adjust for local conditions like heel angle or boat speed to fine-tune accuracy. Regular checks on battery status via your network keep things running smoothly, and its low profile reduces windage for better boat balance.
Real Sailor Feedback: Transforming Downwind Legs
Many skippers report game-changing improvements on reaches and runs, where upwash from the mast can add 10-15 degrees of error. With the T222, downwind sails set more confidently, spinnakers fly true, and your boat speed holds steady. It’s not just about numbers; it’s about feeling the boat respond exactly as it should.
How does the Raymarine T222 improve wind accuracy compared to standard sensors?
By extending 1.35m above the masthead, it avoids turbulent airflow and upwash, providing precise TWS and TWA data essential for performance sailing.
