Wind sensors sit at the heart of every sailing yacht’s decision-making. From trimming sails to optimising autopilot behaviour and analysing performance data, reliable wind information is fundamental. Yet for decades, the leisure marine market has largely relied on variations of the same lightweight mechanical or basic ultrasonic designs. That is now changing.
FT Technologies ultrasonic wind sensors represent the introduction of a genuinely different class of wind sensor to the leisure marine world — one with serious industrial pedigree and proven performance at the very highest levels of professional sailing.
Proven Wind Sensor Technology — Not a Marine Experiment
FT Technologies are not new to wind measurement. In fact, wind sensing is all they do. Their commercial FT7 Series ultrasonic wind sensors are widely used in wind turbine control systems, commercial shipping, offshore installations, and safety-critical industrial environments where failure is simply not an option.
In these sectors, wind sensors must survive constant vibration, shock loading, electrical noise, and extreme weather while delivering consistent, high-accuracy data year after year. The FT7 Series has built a reputation as best-of-breed technology in these environments — so much so that weight is not even considered a relevant specification in its design. Robustness and data integrity come first.
What makes FT Technologies particularly interesting for sailors is that the FT6 Series is not a watered-down marine adaptation. It is a deliberate re-engineering of this commercial technology for performance sailing.
FT6 Series Wind Sensors for Masthead Installation
Performance sailing places unique demands on wind sensors. Masthead weight matters. Aerodynamic drag matters. Response speed matters. And yet, the need for accurate, stable data is greater than ever as modern yachts rely increasingly on integrated electronics, performance software, and advanced autopilots.
The FT6 Series ultrasonic wind sensor was developed specifically to meet these needs. It retains the same Acu-Res® acoustic resonance technology, processing capability, and data integrity of the FT7 Series, but in a compact, lightweight form optimised for installation at the very top of high-performance yacht masts.
This focus on minimising weight without sacrificing functionality is what sets the FT6 apart from both traditional mechanical wind sensors and many leisure-grade ultrasonic wind sensors currently on the market.

Wind Sensors Proven at the Highest Level of Professional Sailing
Credibility in performance sailing comes from results, not marketing. In 2025, FT6 Series wind sensors have seen strong adoption in elite classes such as IMOCA and SailGP — two of the most demanding environments for wind measurement in the sport.
These programmes demand absolute confidence in their wind sensors. Data feeds sail trimming decisions, flight control systems, and performance analysis tools in real time. The successful use of FT6 sensors in these classes is a powerful validation of the technology’s suitability for serious offshore and high-performance sailing.
Why Ultrasonic Wind Sensors Matter
Unlike mechanical wind sensors, ultrasonic wind sensors have no moving parts. This eliminates issues with bearing wear, inertia, and calibration drift over time. However, not all ultrasonic wind sensors are created equal.
FT Technologies’ Acu-Res® technology is based on acoustic resonance rather than simple time-of-flight measurement. This produces a significantly stronger ultrasonic signal, making the sensor far more resistant to vibration, shock, electrical interference, and environmental noise — all of which are common on performance sailing yachts.
The result is wind data that remains stable and accurate when other sensors can struggle, particularly in rough sea states or high-wind conditions.
Key Benefits of Advanced Wind Sensors for Performance Sailboats
For performance sailors, the advantages of this technology are clear:
– Consistent wind speed and direction data with fast response
– No moving parts, eliminating mechanical wear and maintenance
– High resistance to shock, vibration, and electrical noise
– Stable output suitable for autopilot and performance systems
– Compact, lightweight design optimised for masthead mounting
The FT6 Series is also capable of integrating additional environmental data, allowing it to act as part of a broader onboard sensing system rather than a single-purpose instrument.
Cost Considerations for High-End Wind Sensors
It is important to be upfront: FT Technologies ultrasonic wind sensors are not inexpensive compared to many leisure marine wind sensors, including other ultrasonic options. This is not budget technology.
What you are paying for is industrial-grade engineering, proven reliability, and data quality that has already been trusted in commercial shipping, offshore industry, and top-tier professional sailing. For performance-focused yachts, offshore race programmes, and sailors who value dependable data over initial purchase price, the value proposition is clear.
In short: this technology costs more, but it works — and it keeps working.
A Step Change in Marine Wind Sensors
The introduction of FT Technologies wind sensors represents a genuine step forward for the leisure and performance marine market. Rather than adapting lightweight consumer designs upward, FT have taken proven commercial technology and intelligently engineered it downward to meet the specific needs of performance sailing.
For sailors who see wind sensors as a critical component rather than an accessory, the FT6 Series offers a compelling new benchmark in accuracy, durability, and confidence.
As performance sailing continues to evolve, so too must the tools that support it. FT Technologies ultrasonic wind sensors are a clear sign of where that future is heading.
