Hi Just Limin
I have installed a La Crosse WS-1516U-IT weather station on our boatR25 "Blue Socks". It has wind, barometric pressure, pressure trend, temperature, humidity and a rainfall gauge. As an ex sailor, I really appreciate having the wind gauge. It measures the apparent wind when you are moving, but you can, by subtracting the boat speed (or adding if it is coming from the stern) and applying some rough triangulation estimate the true wind speed and direction.
I think the price is about $150. I have mounted the wind vane on the mast, and the temperature sensor under the bimini.
Cheers
Norm on Blue Socks
