Next to the catamaran vs. monohull discussion, the debate about old school navigation skills vs. electronic chart plotters and digital weather prediction gadgets is probably next in line.
Here’s the debate.
One group (include me in this group) argues that you need to learn and know how to navigate your boat without any electronic instruments. You need to know how to use a sextant and have a rather good knowledge of weather systems including cloud formations and other interesting (potentially life-saving) stuff.
The other group argues that anyone with an iPad and a proper electronic chart plotter can set sail and offer a supporting argument that by having 2 of each gadgets on board and plenty of batteries or charging possibilities provides enough redundancy.
I think the latter group couldn’t be more wrong. Let me clarify that point, couldn’t be more wrong when you go bluewater, ocean crossing sailing. For your weekend and coastal sailing no knowledge of celestial navigation and full reliance on software weather updates “should be fine”
However, if you go long term blue water sailing my view is you better know what you are doing and are able to read and interpret paper charts, fix your position with a sextant, calculate speed without your onboard instruments.
Why? Because I think a lot of gadget supporters (don’t get me wrong I am a huge gadget fan) forget one major issue you can have with those gadget and the information on them: Operating System Failure.
True, most gadgets are pretty sturdy, you can waterproof them and might manage to have plenty of battery power on board. I won’t mention a lighting strike here which normally puts all your gadgets to sleep but operating system failure is something millions of Garmin users are experiencing around the world as I type this.
Garmin servers apparently have been hacked or subjected to ransomware. Either way, millions of users have not been able to update or synchronise their devices. This mostly affects users of Garmin wearables but Garmin also provides marine charts, electronic chart plotters and even aviation software.
Now, imagine PredictWind (weather routing and navigation software) or Navionics are one day exposed to a software malfunction? You can have as many redundant systems as you want it just won’t help you if you need to update your GRIB or chart plotter files in the middle of the ocean when you get this message
In Garmin’s case this has been going on for 5 days. Apparently individual systems are coming back online but the point I am trying to make is that you should not lose sight of the shore without knowing your basic navigation and have an idea of weather patterns etc.
Love to hear your view 😉👍🙏
