Apparent wind is easier to calculate on a powerboat than a sailboat. Little heel, not much leeway, no sails to mess up apparent or true wind sensed at the top of the mast.

I'd bet there's an app that can instantly calculate true wind based on known apparent wind and boat velocity. So a home unit could be used as an inexpensive substitute.

Check out Tempest weather instruments.

I have one at home and love it.

Also great for checking out local weather with the shared systems on the map.
