  1. “…over 500 individual wind tunnel tests…” Did any of them involve fat-assed seagulls? In my experience, THAT is what kills wind sensors, not wind. This DOES look reasonable as a wind system, however – I don’t see any data on that cable: diameter, strength, etc. Given the hassles of pulling wire in the mast, wireless is looking more and more attractive 🙂

  2. Valid points, Hartley. And did you encounter the Camden Harbor ospreys that seem to favor high whirlygig sensors? It seems like the birds would learn what poor perches they are, but some think the boatyard trains them.

    I’ve gotten less skeptical about wireless now that I’ve seen longterm reliability with Garmin gWind, Raymarine Quantum radar, and FloatHub, but they use Ant and WiFi protocols, not Bluetooth. Also, to pair the B&G WS320, the manual recommends having it within 2m of the base station, and apparently it loses pairing if the sensor battery goes flat.

    • Matt says:

      The 2m limitation on pairing is to stop the possibility of the WS320 base station pairing to another sensor at power on. This was a consideration for marinas or boat builders and commissioning. The pairing process is automatic and does not require a consumer to put the device into a pairing mode. Therefore, the power is reduced at startup when the base station is in pairing mode initially. In addition, it allows you to check all is working before climbing the mast an attaching the wind sensor, which was a consideration for boat builders and commissioning.

      To reset the pairing, a consumer will need to remove the battery. This eliminated the need to design and build in external buttons for reliability or provide access to the PCB. And in the event of the N2k network being powered down, the wind sensor will go to sleep to conserve battery power.

      A validation boat in Holland with a 27m mast, never saw the battery status go below 95% throughout the winter whilst maintaining a 5 Hz data output over Bluetooth. Charging to 100% during the day and dropping overnight.

  3. The “validation boat in Holland” happens to be Merrimac, and I am very pleased with the performance of the WS320. It hasn’t lost a beat in over 6 months of testing.

    The solar panel is so oversized that it seems completely fine even in winter when we have less than 6 hours of daylight.

    I’m told this sensor is more precise compared to its wired predecessors in both wind speed and angle, and it certainly seems better behaved with more stable direction and believable wind speeds.
