Each sailor will have a PDA that delivers streaming data, replacing the need for displays, wires, and power sources. Some crews will wear it on their forearm, others will mount it in their cockpit.
Every sailor wears a wireless communication unit, but only skipper Jimmy Spithill has talk capability. Regatta-mandated broadcast communication devices will be sleeved somewhere on the buoyancy aid as well.
Every sailor on the boat wears one. In the event of a capsize, the carabineer allows them to clip into the netting “for initial impact.” It also allows them to belay an injured crewmember from an upturned hull.
