Thats my point, theyll still find Hawaii.
Once sorted out in the absence of any navigational aid only than a compass decided to just head due west. Did that. When in sight of other vessels heading west just followed them in. This concern about total electronics failure just seems misplaced to me.
I like charts. They carry a lot of useful information that augments all the other data and I often carry them. But I feel perfectly safe without them. I just prefer having them aboard.

Yikes. Good thing one of you was watching. Did you try raising him on VHF? Probably wouldn't have helped anyway.
It apparently happens though. I was nearly run down in my flats boat while fishing early one morning this past summer when a big, fast CC came ripping down the waterway - I could see the blue glow on the helmsman's face as they passed within feet of me - He was steering by and totally focused on the screen and never looked up even after my air horn blasts. Luckily I heard/saw them in time to move out of their path. (I was running full nav lights including a white 360)
My previous boat was hit by lightning twice within 5 yrs (GA & Bahamas). Most electronics were killed both times, including handhelds intended for backup. Paper charts were available to help navigate until repairs/replacement could be done.
I will therefore always carry paper charts as a (relatively inexpensive) backup for that eventuality.
Some put backups in the stove, fridge, etc as faraday cages...has worked sometimes.
If you have a microwave, it is the best vault for electronics.
Um... what is a "tag out"?
I think it is prudent to be able to know your location after a lightning strike....
Thanks, Backinblue. Makes sense.
I have been aware that a microwave could be a surrogate Faraday box. But I have always assumed the probability of me toasting my electronics in the microwave would be higher than the probability of getting struck by lightning. Circuit breaker is a reasonable compromise!
Unplug the microwave and place blue tape on the front...if you still zap your ele tronics...you shouldn't operate any dangerous equipment....
Or buy one of these....

To test the shielding of a microwave... place a cell phone in it. Call it. If it does not ring it is a fully shielded microwave. If it does ring, then toss the microwave or give it to someone you dislike... you might as well run it without the door on.
Heaving duty aluminum foil wrapped around the device works or multiple layers. The heavy foil or multiple layers is to prevent a rip/gap in the foil.
Great idea, I’ve been wrapping it around my head so the govt can’t read my mind
