6 Tips To Stop Marine Electronics From Ruining Your Cruise

If you really want to get out there voyaging, and enjoy the journey when you do, you need to think carefully about how you use your precious maintenance time. But there is a trap lurking that can waste huge amounts of your time and money:

The reliability of modern marine electronics is simply abysmal.

But this is not a rant to make me feel better about this situation. Rather, in this chapter, I’m going to give you some solid tips, based on 30 years of marine electronic use, that will help you avoid letting these machines ruin your cruise.

Defining The Problem

The first step to dealing with any problem is recognizing it. So recognize that marine electronics are way less reliable than just about any other machine that you will be exposed to in your daily life. Probably an order of magnitude less reliable than:

  • Your car.
  • Your smartphone.
  • Your household electronics.
  • Your diesel engine.
  • Yes, even more unreliable than your Windows computer. Ouch, who said that?

How can I say that? Well, over the years, the vast majority of the marine electronics we have bought and installed have not worked:

  • Northstar GPS (best money could buy at the time): back to the factory, twice.
  • Simrad Autopilot: full rebuild required in first year (poor dealer installation).
  • Lopo Light: four new lights over 5 years. (I classed this as electronic, not electrical, because of the sophisticated circuitry these lights contain.)
  • ICS Navtex: Poor receiver, eventually replaced with Furuno.
  • EchoPilot Forward Scan Sonar: first sensor was weak. Two more sensors have failed in 15 years.
  • Icom SSB radio: weeks of frustration trouble shooting stray RF.
  • Nexus Sailing instruments: Software bugs that rendered half the displays inoperable.
  • Vesper Marine AIS transponder: back to the factory twice, finally fixed (we hope) with a new unit after three years of intermittent problems.
  • Furuno Radar: Funky software problem that threw up strange error messages. Learned to live with that one since it does not effect operation.
  • Syrens WiFi hub system: software so buggy that it was initially unusable. Still doesn’t work that well.
  • Siren boat monitoring system: First two units defective. (Looks like a very cool piece of kit; report coming as soon as we get one that works.)

That’s all that comes to mind right now, but I’m sure there were more.

And it’s not just us. When Ben Ellison of Panbo and Gizmo fame has a cruise from hell like this…well, what can you say? If he can’t get this stuff to work right the first time…

And then there is our own Colin Speedie, AAC European Correspondent, who is one of the nicest and most tolerant people on the planet…until you ask him about his Simrad autopilot.

All in all, it’s an abysmal situation. But given that marine electronic manufacturers are selling to a limited volume market that demands continuous innovation—not exactly a recipe for reliability—things are probably not going to get any better, so let’s look at what we voyagers can do to live with the problem.To continue reading, please login (top right) or join us.

He has sailed over 100,000 miles, most of it on his McCurdy & Rhodes 56, Morgan's Cloud, including eight ocean races to Bermuda, culminating in winning his class twice in the Newport Bermuda Race. He has skippered a series of voyages in the North Atlantic, the majority of which have been to the high latitudes. John has been helping others go voyaging by sharing his experience for twenty years, first in yachting magazines and, for the last 12 years, as co-editor/publisher of AAC.
