Furuno’s New WS200 Brings NMEA 2000 Ultrasonic Weather to Your Helm

Furuno WS200 Ultrasonic Weather Instrument

Furuno WS200 Ultrasonic Weather Instrument

Actually, it brings ultrasonic weather data to your helm. Are we straight with that now?  Okay. The basic ultrasonic instrument has been around for several years — the most recent version, still available, is the PB150, a NMEA 0183-compatible unit —  but the WS200 is a significant upgrade, both in sensors and networking. It’s also a little more expensive, with the listed retail price of $1,395.

New Features

These include a three-axis compass (used for internal true wind calculations), a three-axis accelerometer (for pitch & roll), a yaw rate gyro (for rate of turn), as well as integrating the latest generation Furuno GPS/WAAS receiver. Another key feature of the WS200 is the capability to output weather information in either NMEA0183 or NMEA2000. According to Furuno,

“We’ve also incorporated a unique in-line terminating resistor, allowing the WS200 sensor to be directly connected to any NavNet 3D DRS Radar. This feature allows for a simpler and more flexible installation, without the need to run cables all the way to the main processor. Using this configuration, NMEA2000 data is easily converted and distributed throughout the NavNet 3D Ethernet network. (Please note that while the WS200 has passed NMEA2000 Protocol Certification, we classify it as a CANBUS product, as it is not fully NMEA2000 Certified, due to the fact that we enhanced the product by adding this terminating resistor capability.)”

Complete Feature List

Here’s the rundown on the complete feature set:
