I also considered building an anenometer like this.

The advantages:

1) can measure very light wind accurately
2) Doesn't have a vane to swing with inertia of boat motion
3) no moving parts
4) many updates a second possible
5) possible to extend to make 3d wind sensor


The issues mainly involve rain, or possibly waves and spray hitting it. What about sun heating it?
Does fog affect it?
What about the boat heeling... does the deflected wind make calibration complex?

Maybe a hat to protect from sun and rain is required.
In high wind, the rain will still get blown in.

How about a hybrid sensor?
Traditional vane and cups for wind above 5 knots, and the heated thermistors for very light wind?
