Anyone tried the sail timer wind vane? It's a wifi or Bluetooth wind vane. They also have iPhone/iPad apps. Hope it's good, I just ordered one for $579. http://www.sailtimerwindvane.com/
$580 is a lot of money for information you can get for free. Just look at the tell tales or feel the wind on your face.
I suspect that would be the most expensive instrument on my H260.
I do like the concept. If I had a boat worthy of it, I think I would install one.
