GPS, navigation data, wind data, boat speed, heel, rig loads etc. Onboard electronics are far more accurate and capable than ever before, and with the innovations in solar, hydro-generators and efficient batteries, sailors are able to charge and depend on more electronic systems, without worrying about battery life and excess CO2 emissions.
All of these on board sensors are capable of coming together to generate a huge amount of useful and accurate data, but it all comes to nothing, unless it can be clearly read and analysed quickly by you and your crew. This is where the nke Multidisplay comes in.
