WE’RE JASON AND NIKKI WYNN. A couple of modern-day documentarians, perpetual travelers, and seekers of tall tales.
We’ve been chasing our curiosity around the world on wheels and keels since 2011. Why? Because curiosity is the key to unlocking life. It pushes us outside our comfort zone, softens our assumptions, and helps us embrace the great unknown. The more we let our curiosity lead the way, the more we discover about ourselves and the world around us.
Our home is also our transportation and we spend weeks away from civilization and sometimes land. Self-reliance and living a sustainable lifestyle are a must. It's all about managing our resources and we’re always looking for new and better ways to do so.
We've lived off the grid for over 10 years now in everything from a Van to RV to a Sailboat. And over time we have learned a lot about renewable energy, creating safe drinking water, and managing our waste.
Our journey is ever-evolving but the mission remains the same: #CultivateCuriosity

I worked for 15 years at a leading avionics company where our systems were highly integrated and just about everything was electronic. They went to great depths on designing the electronics to withstand lightning strikes. This included testing the equipment during the design and development phase to ensure it met the design objectives. Maybe the companies that develop nautical electronics could improve the lightning protection of their products.
Have you seen the wiring people do on sailboats? it's a nightmare, even on some of the newer stuff.
@@heavygaming8993 no I haven’t 😲

Great content! Bringing us non-sailor’s a topic and information that keeps us rivited and coming back for more each Sunday. My dad, who was an electrical engineer, always said lightning doesn’t follow rules-it make’s it’s own.
Loved this... We use the trick of putting chains to our side stays and drop them in the water whenever there is a storm as it defuse the lightning, also one from the bottom of the mast. Cheapest version available 😁👍🏴☠️
I've been watching your productions since the beginning. You continually get better and better at your craft. Well done and thank you!
And....
BETTER AND BETTER!!!!
Great comet Partner 💯👌👍
Carl's suggestion of a localized Faraday cage using metal mesh is logical. I read that the charge that builds up in salt water during a storm is concentrated near the surface so I moved the grounding plates to 12 inches from the waterline. Had plates of copper sheet vs dynaplates below the shrouds and the mast. A catamaran, inboard the hulls from aluminum mast and outboard the hulls below the shrouds. An upgrade would have been to ground the headstay. Never was struck in 50 years of sailing, thank God. Good sailing to all you youngsters!
Just a question, in your 50 years of sailing approximately how many lightening storms did you encounter?
@@fredfleming8905 Hi Fred. Many storms. Probably 20+ at least. Also sailed 20 years on merchant ships which being steel are faraday cages and are routinely struck without any effect on electronics as are aircraft.
@@michaelneedham5607 very good I’ve wondered how a good lighting strike damage protection device would work on water. Thanks for info.
@@fredfleming8905 The behavior of lightning strikes on non metal sailboats seems to be not completely understood. Powerful radio frequency pulses which can destroy solid state electronics are generated by electrical arcing. Those fields are blocked by a Faraday cage.
@@michaelneedham5607 It is like EMP (electromagnetic pulse) the Faraday shield will provide some level of protection but not sure if the amps could get so high it would arc through the Faraday shield. Since everything in micro circuits today they are very vulnerable to EMP….also vulnerable to a bad CME. Have a great day.
So, glad you covered lightning. 🌩 Thanks for sharing.
I have a lot of experience with lightning protection. I was an arborist and installed quite a lot in trees. Same problem different materials. I had vertical bronze fingers mounted to the top of each tree with additional finger’s mounted in the canopy branch’s. Typically five bronze fingers all connected to the down cable of braided bronze about 1/2” in diameter and I would run two of them to the ground. One on each side. They were connected to a grid of cables with as many as ten copper ground rods driven radially around the tree out the drip edge. The trees were well protected and I never had any additional damage to a tree after installation. Your system is incredibly simple with just a few ground plates and only one cable from the mast. If I were in your shoes I would definitely install the protection. It is pretty scary getting caught out in a storm without it. It happened once when I was in my early teens while delivering a trimaran to Vancouver Island from San Diego. We lost everything except the sails so we at least could get it back not port.
Good Luck Al Hartley
FASCINATING! Retired arborist here, never seen lightning protection in trees but plenty of storm damaged - one in particular had 50% leaf failure - on inspection turned out to be lightning strike that had traveled through Victorian cable-bracing. I could see entry and exit burn paths clearly.
Florida is the lightning capital of North America thanks to its geography. Florida’s peninsula is surrounded by water that is relatively cooler than the afternoon temperatures over land. Land temperatures reach the upper 80s and 90s on a daily basis due to it being so far south towards the equator. Land heats up quickly compared to the water and temperatures will reach the low 90s by early afternoon. The warm air over the land begins to rise high up into the atmosphere while the cooler air over the water sinks. The rising motion of the air over the land pulls in the cooler air from the water to fill the void. This phenomenon is called the sea-breeze and occurs on both Floridian coasts
The sea breeze acts as a “mini cold front” and showers and thunderstorms develop along it as it moves inland. Thunderstorms easily develop with plenty of moisture in the atmosphere each day, again thanks to Florida being so far south and surrounded by water. As temperatures heat up each afternoon, there is a lot of energy for thunderstorms to use up, grow tall and produce excessive lightning.
Actually Texas has the most strikes ( over 27,000,000strikes per year).
Florida has the most strikes per square mile.
@@hvacmike1175
What is the average depth of the water table in Texas?
Are there deep veins / shelves of water under topography?
Curious .
Clark is an electrical engineer living on a boat for about 30 years. This episode might be worth the time to watch. "LIGHTNING Hits Boats. Here's How to Deal With It [Capable Cruising Guides]

It's been a long time since I've viewed any of Emly & Clark's videos, but it would be nice if YT would let you give me the link so I can watch that one. (Fingers crossed.☺)
I second the recommendation for Clark's video. Here it is: th-cam.com/video/PurMG7KHdW4/w-d-xo.html
@@mikebarron5805 type in the name of the Chanel and lightening hits boat. It will take you directly to the video. Happy Sunday.
Thanks for the heads up, it was a good video even though the only boat I own is a 14 ft fishing boat it was interesting.
Why is everyone surprised that lighning rods work? On a boat the main issue is once a strike occurs it needs to be directed to the water. The copper plates, a steel chain into the water, etc. have been used. This isn't new tech. If you have a locker full of electronics surround it with sheet metal that also grounds to the water (Faraday cage.) Same with cabling, there are metal mesh wraps available. It all adds cost but you have to roll your own dice and consider how freaked you'll be 17 days from land with nothing but a compass and a sextant (that you are hopefully proficient using.)
This solution seems different from a lightning rod. A rod attracts the strike to then channel it, through dedicated cables and ground plates, to ground. Subsequently, vital cables and equipment are protected via the cone of protection. This system seems to try and dissipate the charge diffential and prevent formation of the leader.
Faraday cages are effective for portable electronics like phones and hand-held radios, the most electronics are still connected through power and signal cables.
Would a carbon fiber mast make a difference?
@@patrickjames1080 No
There are solutions for power and signal. Although surge protectors might not be good for a direct hit. Glass fibre data cables will never conduct.
This is not a lightning rod. It claim to deplete ion and prevent the lightning from striking the boat entirely.
Planes have been using this for years. static wicks are on all sizes of planes too. Old technology.
Sailing Dauntless just installed something like that, if not the exact first product you mentioned. Same theory: make the boat invisible to lightening.
Jason, Nikki --
Excellent episode on the practical side. Wearing my electrical engineer's hat: The electrical resistance from the masthead to terra aqua ground (i.e., anodes in the water) must be nearly a short circuit (under 10 ohms) to bleed off the strike's triggering ions to ground. That's what Nikola Tasla's patent shows, and is the science behind lightning protection systems. For boats on the hard, bonding a cable to an Earth ground post (as is done with houses and other buildings) does much the same thing.
The lightning strike basically turns a metal mast into a heating and electrocution element for everything around it -- which causes fires wherever the overloaded, overheated electrical stuff is. St. Elmo's Fire is another form of lightning, when enough charge builds up in the standing rigging to make the air glow. Let's also consider: Carbon fiber composite is electrically conductive (depending upon how it's laminated and assembled, but the fibers definitely so) -- and carbon burns rather easily. Don't take my word for it: Carbon is near Silicon on the Periodic Table -- and silicon is in every piece of digital electronics.
Here's another wrinkle: When your electronics are shot, leaning to use a sextant and compute corrections still makes sense. Old school still works -- one reason I bring few pricey electronics aboard Windwalker when the forecast calls for games of 'dodge squall'.
Blessings, S/V Windwalker
Instead of a sextant I keep a spare old tablet unplugged in a Faraday bag. Costs less than a quality sextant and much more accurate.
@carlnelson8927 The old tablet is still a glass house, and fully charged going into the bag risks being neglected there. Don't need to recharge a sextant, either, plus it doesn't have battery terminal nodes that corrode in salt fog typical of marine conditions.
Not having to do with the catamaran, but it reminds me of Disney World and how much the Imagineers have made the resort "Florida-proof". Disney World has hundreds of hidden lightning rods within the parks. Two of them is on Cinderella Castle in Magic Kingdom and on the Tower of Terror at Hollywood Studios. The Tower of Terror rod is actually quite fitting as the ride's story goes that a paranormal lightning strike from the fifth dimension affected the hotel's elevator on Halloween 1939 and it sent hotel guests to their death. Another way they Florida-proofed the parks is that the hotels and buildings within the parks have been built strong enough to handle different categories of hurricanes. They've really gone above and beyond!
Love the Wynns and cant wait to see the new boat! Happy Sunday guys love ya!
Ty from Sailing Dauntless just did a great vid on this subject. Thoroughly researched and well presented. Ty wouldn't put it out there unless he thoroughly understands all aspects of what's involved to be able to pass that info onto their viewers.
He did a great video and gave access to discount for purchase
I just watched his video and it sounds legit to me. It would be a good idea for Jason and Nickie too take a look at it.
@@dansbrown1313 I wouldn't own a sail boat without one after watching it !! A sail boat is a floating lightning rod.
Ty also did that crappy lagoon repair kit. He admits that it only covers the edge so that hopefully people can resale the damaged lagoon
@@kj5905 it is what it is and it is the factory certified repair to prevent bulkhead failures so that should be all that is needed to protect values. Only time will tell. Personally I would go with what the factory originally told Colin on how to repair it. There are only 2 properly repaired 450's, IMO.
Please don’t stand under a tree while it’s raining; especially in Florida. As your friendly Florida “unofficial” firefighter/paramedic fan, I can’t tell you enough about how this is a terrible idea….many golfers can attest to this as well…We want you around for many more years to inspire and inform us!
OK, but if you stand in the middle of a field or green, aren't you going to be the highest spot there?
I’ve wondered about a similar situation in a boat on a lake. Is it better in open water or near the shore among trees that are much taller?
@@markus717 if you are caught in the middle of a field in a lightning storm… first you should reevaluate your ability to monitor the weather. Second you should squat where you are Until you feel the strikes have slowed down to make a break for the nearest structure.
Whoa, look at the HH jacket! Nice. Interesting topic. Amazing to hear about the cost of lightening strikes. Good to see you both. See you next week. Be safe.
This HH is Helly Hansen, a well known foul weather gear maker, not the catamaran HH.
Curious Minion
@@gonewiththewynns Oh, well, thank you for the info. Be safe
@@gonewiththewynns lol, And here I was thinking that HH Yachts had ponied up for some nice advertising with the cost of your new vessel. 😂
@@mikebarron5805 That is exactly what I thought. Glad I wasn’t alone.
Wowzer. You two have so much to manage. Grateful you do so much research and are proactive. 🌺
The amature radio community has a lot to say about this. Antennas in the sky draining the ions off is the right path but how its done and all the maintenance is the real challenge
I hope you're talking to Colin on Parlay Revival. He got struck twice in the past year... fried all tge electric, and the electronics, but he didn't have much in way of those.
Glad to hear your Mom is ok Jason. Lightning is wicked scary.
Great episode with lots to think about. Thank you!
It's like a life raft, hope you never need it but glad you have if you do.
Thanks for all the great videos. You two are good people, keep it up.
This felt like a training video - in a good way - if you ever need a 2nd gig, do some corporate training vids! You have a good presence on film for those to keep people engaged.
Great to see someone starting this conversation, well done!!!
In the telecom industry we use products like what Rayvoss make. They have been bought out but the actual products are what we call a Transient Voltage Surge Suppressor or TVSS. They incorporate what is called Metal Oxide Varystors or MOV, but the high power grades(100-300k joules class). Rayvoss MOVs are called Strikesorbs. I haven't seen anything equivalent in the marine industry but one should look up the market for an adapted product.
On another note, while not a marine electrician myself, I wonder how well thought out and layed out are leasure boat electrics. How well designed are those blue boxes I see everywhere, as far as electrical isolations is concerned.
Thank you. That was very interesting. I have had damage to my TV & accessories in my home due to lightening. Safe Travels! ❤️
Is it cheaper to install on a new build? Which obviously leads to a follow up video after you talk to HH about putting on yours. Great video, thanks!
I was thinking that too. Or at least set up the boat for a future installation of that cable from the mast. That part sounded like the most expensive and labor-intensive part of doing this.
I am Very Glad that you are looking into this aspect of the Natural World.
Great info! Thank you 👍🏻👍🏻
While Florida may be the lightning capital of North America, the lightning capital of the world is...Lake Maracaibo in northern Venezuela! Lake Maracaibo gets around 1.2 MILLION lightning bolts EVERY year or 233 flashes of lightning per SQUARE MILE per year! How? Lake Maracaibo is the northern part of the Andes mountains. Storms commonly form there at night as mountain breezes develop and converge over the warm, moist air over the lake. These unique conditions contribute to the development of persistent deep convection resulting in an average of 297 nocturnal thunderstorms per year. The lake is also the reason why Venezuela is oil-rich, so it DOES have a benefit!
Wow!! Your content and production in this "short" video is very good. I retired from working over 20 years on radio towers, (where lightning loves to strike,) A large amount of resources goes into lightning protection! My university semester to pass my R-56 certification (lightning protection) was very comprehensive. The results were amazing; 95% to 99% less lightning strikes on the radio towers. HOWEVER, the FINAL lesson taught was. We can guide lightning away from electronics; but in the end. "Lightning Will Strike Wherever the Hell it Pleases."
Great subject and discussion of a very costly and potentially serious problem. Interesting find of a product that claims to protect from both direct and indirect lighting strikes. Please make sure to read all the fine print on they say is covered. Thank for sharing this with us and I like your new jacket.
Breakfast with the wynns. My favorite time of the week
I would be curious about whether insurance companies have experience with boats that have the system. Have they paid claims on boats who have these systems?
This might be an unconventional method of prevention but having Thor sail with you could really help 😁
😆😆😎
This was very interesting and informative, thank you. I especially liked that you talked to people who have been struck.
I know it's been a few days and you guys don't usually look at comments this old, but I'll comment anyway. Jason, that was a great attaboy on your Mom's insurance company for leaving her claim open for as long as she needed it to be. It's so fashionable to slam insurance companies for their poor claim handling, so it's heartening to hear a company (even unnamed) that is doing right by their customers. Thanks.
Two interesting points of information I have come across over the years. I once had a master electrician rewire my breaker panel whole it was live to the house. He had the proper PPE to protect himself from either a short circuit from the main or just leaking current from the bus bar. His gloves and coveralls included a copper mesh woven inner weave in his material that is designed to carry the current around him to the ground. Quite amazing material. It was flexible and he was able to manage his work quite well.
Another is that a ran across an ionizing device once that generated positive ions to purposely counteract negative ions being generated by a nearby field for a reason I no longer remember. The purpose was to prevent accidental discharges nearby very similar to a lighting strike. Curious that the Tesla device you mention is basically doing the same although seemingly passively rather than actively. Seems if you were to generate the opposite ions actively, it would affect a larger area of protection as it would eliminate a larger field of opposite ions.
And a final point, seems that designers could include a conductive mesh under or within a carbon fiber shell, mast, etc to conduct any current away from sensitive electronics. Once built in, it just needs wiring to get it to the grounding plated. It would be cool to watch the testing in a big warehouse bay/pool with a Hugh Tesla generator!
Wow, incredible stories! Thanks for sharing! You both are so good at life, you’ll make the best decision ever! 🙏🏻👍🏻😘🖖🏻
I saw something like this through Tampa Electric. My firm was supplying communications gear to them. Being in the lightning center of America, they had a bunch of expertise at isolating sensitive equipment from lightning. Among other things, they used a similar approach on their infrastructure to repel strikes. They had super slow motion movies of lightning strikes. The strike always starts from the ground and goes up. The connection is made to the potential and the strike completes the circuit to ground. The other thing they had become really good at was galvanic isolation. Anywhere there is communications use fibre optics to replace copper to eliminate a path to the equipment. It strikes me all these expensive systems should have really good (expensive) surge protection, grounding and optical communications.
Good investigation and getting us the information. Thanks.

Sunday morning, 🍿 time.
We lost everything in an RV from a strike. As a former aircraft electronics technician, I have ofter thought of something like this. It seems like a no-brainer to me. IMHO.
Popcorn & ☕ - breakfast of champions! 😆
Sailing Parlay Revival just had another lightening strike and it wiped out a lot of their electronics. I thing the cost was $15k to resolve it, and Colin did most of the fault finding and repair himself.
Been hooked since the RV videos. I never had interest in sailing or boats until watching these videos but now I’m hooked. Can’t wait see y’all sail again on your new boat when you get it.
@2:30 Nice Lagoon Kate!
Thanks! We love her and her newly reinforced bulkheads
Great video, I don’t think that I have ever seen a video or heard anything about lightning strikes on a boat before, I do think that H&H should add this to their boats in production so that the customer has a peace of mind that they are covered.
Generally speaking, anyone will add anything, for a fee 🤷♂️
Very informative video! I wonder (have you asked), if insurance companies would give a discount or better rate if you had this new device on your boat. I also would be curious to know if during the build of a boat, that the install costs would be lower since the mast isn't up.
My company used this technology 35 years ago to protect natural gas installations on mountain areas, not gas wells but compressor stations,. these location had for years have been prone to lighting strikes. It wasn't cheap but each install came with a 1 mill insurance policy. Never had a strike since they where installed. Luv you guys, can't wait for the new boat. BTW we called it the magic hubcap.
I have never thought about that until this video. Jason, hope your Mom is ok and glad she survived the strike.
Holy crow, that’s expensive! I agree that you would think that insurance companies would give you a bit of a discount installing something like this. After all, they give discounts on home insurance if you have an alarm system. (PS I hope everything works out for your mom.) ❤
Boats hit when docked , as in your video ,are more likely hit from by being connected to shore power.
Especially when it's multiple boats .Even boats anchored nearby can by struck by the electricity dissipating from the shore power lines.The best protection is multiple surge guards inline.
I NEVER leave my boat connected to shore power when away from the boat. I've personally heard of 2 boats that were damaged by surge via shore power connection. Does a galvanic isolator protect your boat from a shore power surge? I'm not sure.
@@jeffmooreD40 Yes but the problem is that the electricity from a lightning strike goes out of the hull through the water and allso hits other boats indirectly.
It's better to be well away from other boats.Faraday method seems reliable, but theirs a system called a CMCE worth looking in to.
Very good information. Thx!
The jacket looks great Nikki! Love the Color’s.
❤️🇨🇦
Great video kids. Very interesting what lighting can do to a boat 🛶 especially an electric powered boat. Time will tell if the proposed electrical lighting defuse system will work. I think the price will come down over time as more solutions come on line.
There are cheaper ways of dissipating static. Those frayed ropes you see trailing off the tips of some airplane wings are stactic disapators.
Fascinating! Thank you. As usual, the WYNNS are fantastic at sleuthing interesting, valuable information and expressing it clearly and generously . Cheers!
I love the work that you two go through for your viewers so they are well prepared so thankyou for that. so if you turn everything off like the main battery power, before you get struck by lightning do things still get fried.
So Wise , Thank You . I really hope that it workes. Good luck
Y’all are my favorite sailing channel(even when you’re not sailing🙃)just ahead of”On Board”..keep on keepin’on!
Don’t know how far along your boat is but, have you talked to them since this video about lightening systems?
What do they offer? Does it come standard with something? Is there any upgrade or allowance for another option? Would Ralph sell the equipment to you and you can get it installed while they’re building it, if you decide on it? Would your insurance company give you a discount if you have one? You probably went through all these questions yourselves, just my immediate thoughts after watching. Stay safe and healthy ⛵️🇺🇸
Very interesting. Where I live in East TN there are lots of buildings that have lightning rods on their structures. Glad that you two are researching.
Yeah, I live in Georgia, and I have never lived anywhere where thunder and lightning happen almost every day! I am from the west coast where it barely ever rains, so this is such a new thing for me.
Great content as usual and it was fun to see you in my home town where I lived during my high school years!
Thank y'all, great episode.
Great information. I have been through many Florida lightening storms in a large powerboat with no strikes. Thank the Lord! However, I have lost a number of TVs in my house due to lightening even with household suppressor electrical grid protection. Have also lost large pine trees to direct strikes! Who knows ?
Our friends home burned down even though we were eating with them at our place next door and stupidly thought nothing of the lightning strike which we all knew was VERY close... PAY ATTENTION PEOPLE!
I think this an example of how Nikola Tesla should be honored as one of the greatest geniuses of all time. How he got screwed by Westinghouse, J.P. Morgan, and others is a crying shame. He lost everything to these hustlers and ended up with nothing after all he gave to humanity. And what is amazing is he did all of this before the twentieth century!
I installed a Hawkeye 25 (CMCE25) on our cat. Easy to install and only cost $5250 installed. One boat moored very close to us last year was struck, we were fine. There were two strikes in our marina and we were fine. So far so good, but like you said "does it really work?" who knows but using the Hawkeye, they guarantee you up to $50K in damages IF you have one properly installed along with the same if you are on the hard and the boat is properly grounded.
Thanks very informative. Enjoyed this vid very much.
A lightning story - I used to work/camp in NW Connecticut, lots of 100 foot+ tall pine trees. The home/office I was working from, a BSA Camp, had soda machines against the wall outside the garage. Those machines would get hit 3 to 4 times in a summer! Not the trees nor the house/office were hit! Ever see a Coke machine launch a soda can 40ft! And not just one, but a stream of them!! Lightning - nothing to play with... Fair winds...

Really cool to see you both back where all the magic started and talking about such a fascinating subject, as well.
I actually stumbled across mention of this technology a few days ago while just doing research and so it's really cool to suddenly see you doing an in-depth video on it.
The conclusions at the end were the same for me as they were for Jason: it sounds nice, the scientific principle seems sound and I hope it works out, though the skeptic in me still wonders. It's something worth considering just on the off chance it can avoid such massive headaches and hassles, though.
Awesome content thank you, we do not always think of the hit as it is not always direct
Great post! Thank you for all of this information.
This was incredibly interesting and terrifying (for a landlubber!) thank you! Keep up the great content and safe travels always!
I heard that if you install one of the lighting devices on your boat, you can negotiate with your insurance company and they might lower your rates. If your new boat is all electric, the cost of a refit will be much higher than a conventional catamaran, so you should seriously consider one of these devices.
When our insurance company didn’t renew us after our strike, the only company that would take us required us to get a rod.
Thankyou 👍
That was very interesting, I did see another vlog where they are installing one.
Shockingly good stuff, thank you again, long ago all farm houses had Lightning Rods, we’re they effective?
Love your content.
Remember what you see as lightening is actually the superheated air Chanel’s return stroke.
But lightening can indeed strike from over the horizon and the damage following a strike can only be minimised by routing it straight to earth … either literally or water if at sea. Plucky experienced the worse combination in that the charge passed down his mast and rigging then had to find a way into the water through the higher resistance of his fibreglass hull. It eventually traveled through the inner hull and exited blowing a hole in the hull next to the prop shaft and nearly sinking him as well as leaving dead in the water at an isolated place.
Yes & No. Lighting rods are designed to get hit and redirect the electrical current directly to an earth grounding rod.
Oh Yeah, lighting rods were originally installed on the old farm houses & barns to prevent the lighting from setting the structures on fire. They didn't have any electronics back then & didn't have to worry about the EMP that accompanies a lighting strike.😉
@@vanessabryan786 Yes, he was recording when the lightning struck his mast. And he saved his boat from sinking! /Sailing into HELL Part 1! Lightning devastates Freedom - The sailboat is SINKING! / th-cam.com/video/Df-XCtfU9kw/w-d-xo.html

Yes I watch this channel. Amazing footage of the strikes.
Very interesting and informative video. Thank you
Thanks for the info and efforts.
Hi guys, very interesting device. I get the cost to install is expensive, but wonder if any insurance companies give a break by having it installed? Considering how expensive it is to replace electronics, the hassle of finding a new insurance provider, and the chances of your boat being struck more than once over the time you own it, wouldn’t it be a good preventative measure to install?
I'd be really curious what the actual cost breakdown for that device is. I'm expecting there's special metal milled and polished in a special shape, with hi-tech coatings, high grade dielectrics, high purity low loss conductors, special techniques to route cables and bond to the conductor plates on your hull. Maybe $2500 to make, 100% markup, $5000 of labor (50 hours x $100/hr) with up to 100% markup. The high price gives buyers some sense of security - every year you have hundreds of thousands of yachts not hit by lightning, the vast majority. Every one of them who has the device will swear by it every year. Even if it does nothing there will be huge numbers of false positives. And if it does work it could take a long time to figure it out with reasonable certainty - statistical significance. For that reason I'm pretty sure the manufacturers will end up offering a money-back guarantee on the device (but not cost of repairs) for anyone who gets their boat hit and still make $$$. Kind of like all the high security bike locks who at least give you a refund if the lock is compromised. It is worth it in marketing.
I'm guessing it won't be long before there are DIY plans, or cheap knock-offs for a few thousand and self installs. Sure you wouldn't get the experience of someone installing it over and over and there would probably be some compromises on materials - and it still may fail just like a pro-install might - but I'm pretty sure this will happen as the market expands and competition grows.
Of course best option is yacht builders include this as part of the original build and masts come with ion-discharge conductor paths builtin - install costs should be way less, mass manufacture and competition drive prices down. But like all safety features these things take a long time to percolate through the market and ultimately lightning damage sells more product so there's not as much incentive to push it unless customers demand it. What will be needed is some very solid research of actual vessels and analysis of data. They could be packing the masts of early adopters with lightning detectors and impervious data loggers and offering discounts because proof that they work will be worth its weight in gold. But really they don't have to prove anything right now - if you're buying a $1M+ yacht then $15K for a lightning prevention system is probably an easy sell until there was definitive proof they don't work. And if they do, game over - every insurance company will offer discounts and everyone will take the option.
Really informative! I can't afford any of it, so I'll just squint and pretend the storm isn't there. If I can't see it, it can't get me!
Yeah, been there done that. We live in a metal clad barndominium on the top of a mountain ridge in Arkansas, surely lightening strike capital of the US!, and do not have a lightning rod. Lots of folks say we don't need one as the whole building directs the energy into the ground naturally. This is informative.
I am curious if the amount of carbon fiber in the HH will effect how the boat would deal with lightning as carbon is quite a good conductor compared to other composites. Being in FL, I have always thought it smart to protect everything outside from strikes since they are so common here. Seems like a rod, or the device you are talking about connected to grounding points would be a great piece of mind investment. Great content you two, always love catching up each week with your adventures!
I think this is a fairly major issue. Carbon is a good conductor but it has to be separated from aluminum and other metals by insulators, typically a thin layer of fiberglass, to prevent corrosion.
A lightning strike is going to blow through all those thin insulators, which will then vaporize because they're resistive enough to absorb a fair bit of energy. A small blob of fiberglass plasma in the middle of lots of carbon fiber is basically a small bomb, maybe as small as a good-sized firecracker, maybe much bigger.
I think it's even more important to protect a carbon boat with (a) a low resistance discharge path from the highest point to the water, and (b) insulator blocks on all the stays, like what you see on the guy wires on utility poles.
It's incredible that we are rediscovering how Nikola Tesla helped to build our world 80 years after his death. The product seems expensive but sounds like it would be worth it to not deal with an electrical refit and insurance. Thank you for sharing this info!
👍👍
And lets not forget about Faraday and EMP.😉
Re: Tesla, we would be decades ahead of now if the government hadn’t confiscated all of Teslas research data when they found him dead in his home. He was above genius.
Interesting!! Well done!
Great video - thanks for all the information!
Good video, In addition to the device mentioned in the video, one additional measure that can be taken to protect electronic systems on a boat is to place them inside Faraday cages. Each electronic piece could be placed in a small Faraday cage, and lightning arrestors could be installed on the cables entering and exiting the cage. The cages could be grounded to either the water or the earth when the boat is on a hard stand. This setup would provide an additional layer of protection against electromagnetic interference and other electrical hazards, including lightning strikes. However, it is important to note that direct lightning strikes can still pose a significant risk to electronic systems, even when they are enclosed in a Faraday cage. Thanks for your video and information, looking forward to your next video.
Parlay already struck 2x and Dauntless is installing a really spiffy device to try and prevent a strike on their boat that looks a bit like this and also claims Tesla patents - we'll see! Not sure it's the same device but it'll be interesting to see results when a bunch of popular boaters begin running them.
I have the same device that Dauntless uses and have done extensive research and have talked with many technicians regarding the science behind the CMCE device, it is PROVEN and effective. There is 100% confirmed way to avoid a strike and it is in the sience behind ion dissipation and neutralization.
Jason and Nikki - long comment but hopefully helpful. I spent a several years helping install and test a lightning prevention/surge arresting system on a long gondola lift in Colorado's high country. It did reduce direct and proximal strikes, and did shunt induced surges to ground without damage, but not 100%. Sometimes we had to replace arrestor equipment, but that was much cheaper and easier than replacing the operating electronics. My concern about the ion collector atop the boat mast is that it is very small and may not do a good enough job of collecting ions to dissipate. A larger array is advised. But any dissipation PLUS the secondary arrestors on each circuit and electronic device for induced surges will make a difference. I would install both to reduce the risk of a blowout while at sea, as well as the hassle of equipment replacement and having to find another insurance company afterward.
Very good video. Nice job. Enjoying the channel. Tks for sharing.
What about surge protectors? If used on all of the equipment it might protect certain items against a hit? Just wondering!
simple surge protectors don't work all that much, they take time to fail and allows some or all of the surge to continue trough a bit, I have found the running 6 or 7 protectors together in series will work, would also need to keep a bunch of spares, protectors are make using a device called a thyristor, you parallel 2 together, at a set voltage they short out stopping a surge, so then you would make 6 or 7 sets of 2 and set the 2 unit sets in series, depending on the type they can go for $7 each to over $1000 each,
If you want to keep the lightning protection in place when hauled out, have the installer drill and tap a hole in the hull conductive plates. Then when hauled out, screw in an eye bolt and hang a length of chain from it that touches the ground to keep the conductive path to ground intact. This product is working like home or commercial lightning protection system by creating a path to ground around the electrical insulation properties of the hull. Before launch, plug the tapped hole with a plastic screw to keep marine growth out of it.
Would require constant power ... but if lots of solar/batt... and you do not turn off/disconnect everything when on land(which you should do as this protects against lighting for the most part) then you could leave everything up and running.... Not hard to drop an uninsulated wire from the grounding plates to the ground.
@@w8stral I suggest consulting a marine electrician. 😉
This does not work it’s fibreglass boats attaching a chain to plastic is like darn right silly
@@michaelking7231 and I never said attach to plastic. I said "drill and tap the hull conductive plates" that are already there and are already intended to provide a path to ground from the mast into the water. Simply ground them on land with appropriate measures.
Thanks!
Thanks for the 💙💛💙!! Cheers!
Always golden content.
Not a sailor, but the technology seems promising. My only problem is laying out 15 grand for it. Also, I would assume there are a lot of proximity strikes to boats, and if I understand it right, there's no guarantee on those types of strikes. It could end up being a $15,000 shiny hood ornament.
Since getting struck is somewhat random, ya don’t know if it works until it doesn’t 😂
The cynic in me, and lets face he's in control, says you'll know when a lighting system works the minute the insurance companies offer a discount for it..
This is a great vid on lighting! Very educational.
One of my fav channels along with the sailing brothers
Every time the subject of lightning strikes comes up I wonder, to myself, what does the Navy do to protect their ships and equipment. I figure they have been at this for a while and have tried various approaches so what is the current state of the art strategy used by the Navy?
That might be different in that the steel hull and superstructure become a Faraday Cage, protecting the contents.
Steel hulls have a huge advantage. The entire hull acts to dissipate the charge because it's conductive. On a glass or wood hull it all acts as an insulator except for the electronics. Top of the mast usually has an antenna or at minimum a lamp. Those connect to the power and grounds inside the craft. All the electronics also connect to the engine which has a shaft that goes into the water. That provides the conductive path and lightning looks for the easy path.
The Navy is aware of the Faraday cage and uses that principle even when building wooden boats.
@@peterengel7885 A faraday cage is good for blocking radio emissions but does nothing to protect against high current and voltage where it was never intended to be. There has to be a strategy to protect all the electronics. Perhaps that strategy is just to cary spares and make repairs onboard as you go. Damn the lightning, full speed ahead!
