Wireless sailing

Sailing World is running an article on how wires are being obsoleted by some interesting wireless technology developments. This could save cost and improve sailing performance at the same time.
“Is it far-fetched fantasy? Nope, we’re talking here and now. With advances in wireless technology driven by worldwide market demand, racers can either equip their boat with a complete wireless system or upgrade existing instrument systems for wireless data retrieval and display. Wireless technology will allow racers to shave weight all over the boat. There may even be cost savings in boat construction, as boatbuilders will no longer have to spend precious time leading wires.”
