We want to get a trawler style boat and travel parts of Asia, N & S Pacific islands/counties, PNW, Alaska, US east coast and parts of Europe.
There is some risk with this plan both physically and financially.

:laughing: But as our oldest says, YOLO! :laughing::laughing::laughing:
What worries me the most about this plan?
- Pirates? Nope, you can pretty much avoid them, though areas in the PI that used to be safe, are a bit iffy today.

- Storms? Nope, These can be mostly avoided and the boat we would buy can handle any likely storm we would encounter.
- Reefs, Rocks, barely floating shipping containers? Sorta. The boat design we would buy has had a boat run up on a reef for a couple of weeks, one hit an ice berg, and another hit rocks at 13 knots with no damage. Having said that, it is best to avoid, reefs, rocks, icebergs, and shipping containers. :laughing:
What DOES worry me is a lightning strike on or near the boat. Lightning DOES sink boats as well as destroy all/most/many electronics on the boat. The boat we want is metal which is supposed to minimize the chance of being hit and supposed to minimize any damage. Key words, "supposed to minimize." Minimize ain't zero probability.
Since boat diesels have to meet emission requirements this requires engine computers, a lightning strike can kill the engine, which could kill the boat and thus kill the crew. All the diesel engines for boats meeting Tier 3 are electronic controlled and if EMP kills the computer, so goes the engine. I talked to some JD marine engine guys about this and they confirmed my fear. There is no backup way to run the engine if the computer is fried. Furthermore, one of the consumables on emission controlled engines is not only fuel and air but now it is power. If the engines do not have power, they no workey. So if the engine computer some how survived the lightning hit but the alternator was fried, well you will be bobbing in the water.
This level of vulnerability is not a problem for a truck or tractor running on land, you just stop. On a boat this very well might cause a boat loss and maybe kill the crew.
I am trying to figure out how to build a Faraday cage around the boats helm station to protect the navigation, engine controls, and autopilot systems. Not sure how you could do this around the engine. The boat is built with lead around the engine room for noise reduction so maybe that along with the metal hatches and metal hull reduces the EMP vulnerability close to 0.

Need to ask the builder about this....
From what I have read, a Faraday cage has to completely cover the systems to be protected. Any gap or whole can allow in the EMP. Since the helm station requires cable access for systems, sensors and power, one would have to be able to quickly disconnect these cables and close a cover over the cable opening as well as covering the helm itself. This would require you to go blind since your AIS, radar, engine controls, auto pilots, etc, would be under a cover and unpowered.

Since the boat is all metal, car like if you will, in theory a lightning strike would flow on the outside of the boat pilot house and hull. So the crew would be protected from the power of the lightning but the EMP could be a problem due to window openings. I wonder if I can get gold embedded in the window glass like on the EA-6 Prowler or the rumored diamond coatings on the F18G Growler and F22?
