Navigating a sea of change for better marine connectivity

Kurt Krutsch, Molex

Modern boat buyers have come to expect 24/7 on-demand device connectivity, conditioned by the same ubiquitous access and functionality they enjoy elsewhere — whether in their homes, offices or cars, not to mention other forms of transport, such as rail or even air travel. Raising the bar on boating performance, safety, communications, convenience and comfort makes good business sense. Following the lead of automotive manufacturers, boatbuilders are recognising the value of strategically incorporating proven electronics to enhance functionality, heighten brand appeal and competitively differentiate their offerings. Technology commonly found in homes and cars is migrating onto watercraft, including security cameras, infotainment and connectivity for mobile devices, including laptops, tablets and smartphones. As markets expand for integrated satellite

systems and Ethernet, so too will demand for onboard apps, controls and connectivity. Reliable onboard connectivity can also translate into improved safety, better diagnostics, simplified maintenance, actionable intelligence and lower lifetime costs for boat operators. Designing the connected boat Marine communications face the same challenges as land-based communications — but with the additional problem of equipment being constantly surrounded by water. Strong, reliable signals, and grounded electronics, are basic requirements, but casual boaters and professional sailors also need reliable internet bandwidth and onboard monitoring systems to aid effective and safe operations. For over a decade, the National Marine Electronics Association NMEA 2000 standard has guided boat

manufacturers and operators to meet the increased demands of networked communications and internet protocols. On-board networks must be capable of withstanding harsh conditions on the water — while performing reliably and consistently. But while on-board safety and enjoyment relies on dependable technologies performing unfailingly, seasoned boat owners and manufacturers recognise the complexities of marine electronics system design. About 70 to 80 percent of network failures occur as a result of a mechanical failure involving cabling and connectors. In harsh, heavy vibration marine conditions, electronic components are at higher risk of being jarred loose or exposure to corrosive salt, lubricants and other chemicals, which can lead to hours of frustrating diagnostic activity chasing down and troubleshooting network problems.
