At any rate, with solar and wind generation onboard, they were covered if something catastrophic happened to the ships wiring.

The gear they had, laptops, smart phone, tablet, isn't too unusual these days. You could find it in a family kitchen.

But for boats that are comfortable with electronic charting as their sole means of navigation, they would not put that trust in one single system or onboard source, they would have several redundant unattached devices.

Not everyone accepts their way, but I know their seamanship is top notch!
When you are at sea for a few weeks or amongst islands that have no technical resource, it is not uncommon to lose all you electrics simply by not having a charge source.

So in addition to an expensive chart plotter, you also have to have passive charging systems. Many of the cruising boats out there have none of that stuff and most have a modest house bank as well.

So of you have just an alternator, it doesn't matter how many electronic devices you have, they will all have flat batteries. No lightening strikes or other exotic happenings, just a dodgy alternator is all it takes.

Anyway, in NZ we have always had to pay for paper charts so excuse my lack of concern for you plight
