Coastal
The WS320 wireless pack is our default choice for retrofitting 30-40 ft sailboats. 1-2 h installation from the dock, annually replaceable battery, immediate Triton² integration. The ±2° accuracy and 1 Hz frequency are more than sufficient for summer cruising.
Budget pack + installation: ~ $1,700 USD ex-VAT
View WS320 packOffshore
The WS710 or WS720 wired model provides long-term reliability (no battery) + 5-10 Hz frequency useful in rough seas. Our workshop standard for sailboats 40+ feet with mast lowered during refit.
Sensor + installation budget: ~ $2,800–$3,400 USD ex-VAT

The WS730S Ocean spec (€3,080 ex VAT) — 3D ultrasonic, 20 Hz frequency, ±0.3° accuracy — is the international racing standard. For French racing, an equivalent alternative is the NKE 3D HR II (~€2,800 ex VAT, project order).
Sensor-only budget: ~ $3,080 USD ex-VAT (excluding H5000 / NAC-3 and displays)
View WS730SThe 0° orientation of the sensor must exactly match the bow of the boat. A 5° error = permanently offset wind reading, polars no longer matching. Validate with GPS + compass before commissioning.
Wind is turbulent in the top 20% of the mast (interaction with mainsail and topmast fitting). Always mount the anemometer 30-50 cm above the masthead to get clean wind data.
The sensor cable carries a very sensitive millivolt signal. Next to a cable carrying 80 A at startup = measurable electrical noise. Always separate signal cables from power cables.
4 questions to identify the anemometer suited to your sailboat.
Minimum 30–50 cm above the masthead to avoid turbulence created by the mainsail and the topmast. On a gaff-rigged racing sailboat, up to 80 cm. The 50 cm setting is a good compromise for cruising and racing.
Yes in 90% of cases with NMEA 2000/0183 interface on the existing setup. The ultrasonic sensor uses a dedicated interface and publishes to the N2K bus. The existing mast cable is often reusable.
Typical lifespan: 10–15 years (B&G WS720/WS730), 12–18 years for NKE 3D HR II with 5-year overhaul. The #1 failure cause is water ingress into the housing — select a marine-grade model certified IP67.
Yes, via the NMEA 2000 interface of the WS320 pack. The wireless sensor transmits via radio to a base unit connected to the N2K bus. Radio latency 100-200 ms in worst case — imperceptible for cruising, but noticeable in racing (prefer wired connection).
Not mandatory but highly recommended beyond 40 feet in rough seas. The vertical component of the wind (pumping in swell, wave accelerations) introduces errors on a 2D sensor that the autopilot interprets as heading changes — resulting in oscillations. The 3D sensor filters these out.
