Top-notch Wind Indicators
A step above those silly bits of yarn (which work quite well, BTW).
That fragile plastic wind vane at the masthead looks like a childís toy to a lubber. Itís a nautical curiosity perched at the top of yacht that is also equipped with a comprehensive electronics suite. While we can certainly sail without wind indicators and telltales, judging the strength and direction of the wind by its effect on the sails and the feel on our neck, those little bits of plastic and yarn are darn handy when trimming sail, or balancing the helm.
