B&G Vertical mast top unit - 1800 mm without mast cable

The WS740 high-performance wind sensor offers superb aerodynamics and accuracy. A 1.8m high modulus Ocean spec carbon spar elevates the wind sensor into clear air, above any sail-plan disturbance at the masthead.
The WS700 series is the ultimate wind sensor for performance sailing, providing the most accurate wind angle and speed data. The new one-piece vane design gives superb aerodynamics and stability, as a result of over 200,000 hours of combined design and wind tunnel testing.
Higher altitude for clearer readings
The vertical spar minimises the effect of sail-plan on wind measurement ensuring the best performance with minimum calibration. This means reliable True Wind Direction to make precise race calls when needed and better steer-to-wind performance in all conditions when on autopilot.
Flexibility
Choose from 6 options of vertical high-modulus carbon spars from 0.8 to 1.8m**
WS700 series follows the same physical mounting as previous models (VHMU) providing an easy upgrade path.
Wide compatibility
Connect directly to H5000 or WTP3 via a NMEA 0183 input or to NMEA 2000 via the wired interface (sold separately)
Straightforward installation
WS700 connects to your instrument system via a single mast cable, available in 4 different lengths from 25 to 80m.
