TECHNICAL - THE POWER OF DATA

Video on your chartplotter, night vision cameras up the mast, and wireless gadgets galore are now a reality on many cruising boats, but the digital networks they use are decades out of date, making them slow and open to hacking. It’s definitely time for a new kind of onboard network.

To date, sailors and equipment manufacturers have been able to link devices using the networking of NMEA 0183 and, more recently, NMEA 2000 (N2K). These options provide a data backbone by which all instruments are able to talk to one another. It means that no matter what make your echo sounder is it will be able to talk to your instrument display or chartplotter, even when it’s created by another manufacturer. However, NMEA 0183 and N2K are both relatively low-bandwidth systems that service a limited number of sensors and displays and can only support limited amounts of data. When N2K superseded 0183 it increased the data limit, but increasingly sophisticated technology onboard is far more bandwidth hungry.

This has not historically been a significant problem as the closed-loop, unconnected world of a boat in the middle of an ocean is extremely limited. But speed, bandwidth and networksecurity demands change dramatically when raw radar and sonar data feeds are being shared with networked wireless devices, alongside live video feeds, wireless cameras and linked online to the internet.
