You can get NMEA 2000
smart sensors for wind
and speed/depth, from Airmar, Maretron, Garmin
, and others. The data can be displayed on a NMEA 2000
MFD (any brand) or instrument displays such as GMI10. In fact, you can get 2 GMI10 displays and NMEA2000 wind/speed/depth sensors for less than the cost of a set of Raymarine
ST60+ instruments and you gain in redundancy (any display can show any instrument) and interoperability with MFDs.
NMEA-2000 certified instruments from different manufacturers are pretty easy to network together. Mix and match as you like.
