Coastal
Bevielis WS320 paketas yra mūsų numatytasis pasirinkimas 30-40 pėdų burinių laivų atnaujinimams. Įrengimas užtrunka 1-2 valandas nuo prieplaukos, baterija keičiama kasmet, o Triton² integracija yra tiesioginė. Tikslumas ±2° ir 1 Hz dažnis yra visiškai pakankami vasaros kruizui.
Pack price + installation: ~ 1 700 € HT

„WS730S Ocean spec“ (3 080 € HT) — ultragarsinis 3D jutiklis, 20 Hz dažnis, tikslumas ±0,3° — yra tarptautinės regatos standartas. Prancūziškai regatai alternatyva — NKE 3D HR II (~ 2 800 € HT, projektinė užsakyma).
Sensor-only budget: ~ €3,080 ex VAT (excluding H5000 / NAC-3 and displays)
View WS730SThe 0° mark of the sensor must align exactly with the bow of the boat. A 5° error results in a permanently offset wind reading, causing polar plots to no longer match. Validate alignment using GPS and compass before commissioning.
Wind is turbulent in the top 20% of the mast (interaction with mainsail and top cap). Always mount the transducer 30-50 cm above the masthead for 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 wind transducer / vane anemometer suited to your sailboat.
Minimum 30-50 cm above the masthead to stay clear of 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 cruising/racing compromise.
Yes, in 90% of cases with an existing NMEA 2000/0183 interface. 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 a five-year overhaul. The primary failure factor 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 by 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).
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. A 3D sensor filters these out.
