The Fine Art of Sensing the Wind

The cheapest wind indicators are bestowed at birth: your nose, the back of your neck, and your fingers. Forget digital precision; these wind indicators are dialed in. They even sense changes in temperature that, in squally weather, can signal a sudden backing wind. Even the most sophisticated wind sensors can't compete with a direct skin-to-brain link. The next step up from our dermal cells is a bit of yarn in the shrouds-super light Angora wool, if youre a stickler. Here, the eyes intervene in the process, so the brain must do a bit more exercise. Well call this soft technology.

How To Connect Small Wires

The popularity of micro-electronics and LEDs has greatly increased the number of small wires on board, and whether the added eyestrain is a fair trade-off for a lighter, more energy efficient boat depends upon your perspective. Fortunately, some welcome accessories are relieving the headaches associated with joining two wires of tiny diameters-at times as small as button thread.

Calypso Wind Reader

Wireless wind sensors offer many advantages for the sailor. In recent years, weve tested Raymarines Tacktick, the Nexus Gwind, and the Sailtimer. (See PS March 2014, Wind Sensor Testing online, as well as the followup articles in the May 2014 and August 2014 issues.) All worked well, but some were certainly better than others. Features we rated included durability, battery life, accuracy, ease of use, and ease of installation. One interesting new entry into this field is the Calypso Cups 4.0 system, which combines a Davis Instruments wind sensor with a user-friendly smartphone app.
