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

We're super stoked about getting into the world of Performance Cruising and hybrid electric sailing with our new HH44 catamaran. HH catamarans have a reputation for building the best luxury performance sailing catamarans in the world. And now this is a brand-new boat designed from the ground up with solar, Hydrogeneration, and electric motoring in mind.
This is why we want an electric tender that continues this theme of self-reliance and sustainability. Because if we can cruise without ever needing to hunt down fuel on a remote island, well, that will be the dream!

Wow, that last one was amazing. Can't believe how fast it goes with electric propulsion. That was definitely the coolest, with the jet drive.
Try a jet ski. Hold on tight.
@@markbernier8434 Jet ski’s aren’t electric are they?
@@artat777 No, but they are a charge and a half. You heard Nikki screaming at 10 knots. Try that at 50.
@@artat777 Taiga makes a model called the Orca and it's an all electric jet ski.
Jet drive for sure with upgraded battery potential that's the winning ticket right there
Lol, my face was hurting from smiling and laughing so much when you were testing that Zero Jet. Then when you said it’s no longer a need it’s a want because it’s so coooool!
If you want help deciding, remember he can’t put a price on happiness!
You two are amazing in being able to line up these options to test. That must have taken a lot of time to arrange. Congratulations on a very informative video, as you always do.
What fun! ... and to be able to test the hardware for YOUR needs is PRICELESS!
If you are basing your decision on “smiles per watt” I would say the jet propulsion was your favorite. I also think that’s it’s ability to run in shallower water, faster top speed, and the ability to run from danger/weather makes it a good option.
and don't forget that with a jet, there's no spinning propeller or other moving parts under the water, so for a diver, this is a huge plus too, from a safety point of view.
Sure has my vote!
All good arguments for sure. But I would point out the relative fragility of a jet drive. They have wear items like wear rings, and it can be difficult to clear debris that gets lodged in the intake or impeller. Impellers are also precision items, which means you can't get one that isn't perfect in a remote location and deal with the imperfection, but on a traditional drive if the available prop isn't quite the same as the old one you can still make it work. Also not being able to pull the drive leg and take it somewhere for service is another maintenance drawback. I think where I live in the US I would love that jet tender, but I'm not sure I'd want to take it anywhere remote and rely on it at all.
@@JheregJAB eh, The impeller in my 200 hp supercharged Sea-Doo from 2006 has never been changed is rusty as and so is the drive shaft haven’t changed the wear ring in years Rarely pick up any debris and I definitely run through a lot of seaweed and still does the factory top speed of 70 miles an hour like a champ
One of your best videos! I really enjoyed this one. One comment is that you could carry a small solar panel to recharge while you are on the beach, or diving, or whatever. One thing I did not hear was how easy to steal each one was and what the recharge time is.
I recently made a similar conversion from a heavy RIB + petrol o/b to a lighter catamaran dinghy (True Kit 3m) + electric o/b (ePropulsion Spirit). Love it. Range anxiety is more significant than range limitation itself. Also bought the solar charging panel. Have kept my petrol o/b as a temporary measure ‘just in case’ but haven’t used it the entire season.

Don't normally comment but I appreciated this 2 part series. I have been intrigued by the OC tender and the idea of an electric power system. You did a fine job of displaying the different options. Thank you.
The jet boat did bring a smile to both of your faces.... Can you really put a price on that?
It seems like the ultimate adventure vehicle :P
What an awesome test series- and, really relevant to the times. I'm NOT surprised at how few choices there are and the weight cost of ever increasing reserves- but, it's really nice to 'see it' in real life- working, running and providing service. Even though LiFePO4 is the best thing since sliced bread- it's NOT the answer to our dreams...yet!
Thanks Nikki and Jason for this! We are currently researching for a tender and electric engine without the ability to get our hands on some of these new ones out there to try. This is immensely helpful.
I am so happy for you guys, you have worked hard to archive your dreams! Praying for you your new boat and that you find the right Dingy! Good Vibes and Positive Energy to you through this part of the journey! Cheering you on!!
Wow! Thanks for sharing! Like #11. It is a jet boat so you don't have the depth of a prop motor. FUN!
Seems like waiting for the hydrofoil would make sense since you probably have a year or two to wait on the new boat. Also investigating if the 440 lbs weight limit can be raised would make sense or figure using your boom to lift a second battery pack that you would only load if you were going on an extended range trip.
You're not lying about things being scarce and becoming even more scarce for remote places. Take a look at the Inuit towns of northern Quebec for example. There, you can get your hands on a bottle of fruit punch for 10.79 Canadian Dollars, a package of vanilla cookies for 18.29 Canadian Dollars, and a box of frozen chicken nuggets for get this...26.89 Canadian Dollars, *NEARLY THIRTY DOLLARS!* I'm not kidding, but why is it this way? Because everything is flown in on a Combi plane (as in a dual passenger-freight aircraft) since there are no roads connecting these places to the rest of Quebec, and so whatever is taken off that airplane is what you're stuck with. And it doesn't help when there's an economic crisis.
And don't sweat it, it is okay to make and admit a mistake, we are humans after all. We're bound to because nobody's perfect
Priceless reaction!! LOVE IT!! We are so glad you got to experience the 360s :D
Any plans to bring down battery weight? Cool concept but at 50% more weight than an old torqueedo battery and about 30% more weight than a hot-swappable avator battery it adds up.
For safety reasons, if you ever had to abandon the Cat, a gas tender will give you the range to possibly make it to land. Or, the speed to make it to shore if someone is injured.
Gas will also allow you to go multiple tanks worth of range. While it may be possible, it would be VERY difficult to bring solar panels. Charge controller, and enough batteries aboard the tender to accomplish the same on electric
wriñg
You gotta do the missile test, it's the most important one! Allow me to aim a missile at your new catamaran, and if it survives, then it's a _Wynn_ in our books. And it's very important to thank Scranton for being the Electric City. Make sure you stop by Cugino's for the tasty bread
Self-reliance is important especially when you have nothing else to turn to, that's been our situation and we're still going strong
Who knew that the Supreme Leader has both a decent sense of humor and a fine taste for local Italian eateries in the Wyoming Valley? I credit his Swiss education.
Best test video’s ever. Love the fact you will be turning sailors onto electric motors. These technological break through will change sailors green, practical and future outlooks and our marinas forever!
That was some great information on the tenders. It is really helpful for you and these nice companies to put this stuff out there for all of us. More demos please.
WOW that Zero jet looked amazing , 20Kts & the hydra foil option looked so cool , Lov to see a test on that one , Thanks .
Thanks Bill :D
I would go with a hybrid option. Gasoline outboard for high speed long-distance runs. Electric outboard for short trips to the beach or the dock. If the gasoline outboard fails to start you have the electric outboard as a back up.
but ya gotta carry both... :-(
They're trying to keep gas OFF the boat, though, so that they only need diesel for the boat backup generator.
Extra batteries for longer trips. If it were me, I'd carry a backup motor on the HH44 rather than a gas outboard as a backup. It'd be great if the same battery model and form factor were used for both the HH44 and the tender
The zerojet looked like a good option, but as others have commented, impellers can get damaged pretty easily. Check on availability of replacement wear rings and impellers as you will become very familiar with changing them out.
i appreciate your togetherness, life with a your choice should be about ONENESS and developing this and I see it you you as a couple. THANK YOU for being a model that taking care of each other really pays off!! Love yall!!!
Keep one very important thing in mind... The "dingy/car" is also your last line of defense to pull or push your boat around in case of emergencies.
They have 2 electric high brid diesels man and several sails man.
For thousands of years all people had were sails, I think they’ll be fine
They are well equipped/getting there, but you miss the point: emergencies happen.
It’s a good modern technique that can save boats and lives.
@@It-b-BlairWisdom!
When we were cruising in our trawler we carried two motors…a 15 HP Yamaha and a 3 HP. The small motor was our “harbor” motor. Light weight, easy on and off and we used it traveling the ICW. Unfortunately this was before Torqueedo. In the Bahamas and the Keys we mounted the 15 HP for speed and range for trips to the reefs and going to town. Something to consider.
Agree -- most of the time, use electric. In the event they need to make a long trip (like they did in the Bahamas), use the gas.
Redundancy as well.

You were both smiling ear to ear the WHOLE TIME you were in the zerojet.... That motor on that OC is a winning combo! What a perfect dinghy, especially if you can hot swap a "get home"/"limp home" backup battery...
"My Cheeks are starting to hurt" lol... that's when you know you're having a blast. Nautical Smiles Per Hour
I vote for the Zero Jet : ) Recharge time will be of interest. The beauty of electric is that you will not need to store gas cans (that are a fire hazard) and with your HH44 electric infrastructure you have free solar power for unlimited use of your new Zero Jet.
the new ship will still have a diesel generator, which means that it will also have diesel on board
If they have 3kW of solar and if they have the 10kWh battery then charging from. ~0 to 100% will take 3hours. 5kWh of solar 2hours. A 240v standard wall socket (international standard socket) ~4h 15min. A weak 110 10 amp USA socket ~9 hours.
Exactly, keeping gasoline (petrol) off the vessel would be amazing.
Indeed. No hauling and filling cans or the constant worry about spillage.
@@tihomirrasperic I thought they ditched the generator because of the high solar output and large battery bank?
That ZeroJet is similar in speed/maneuverability to our Yamaha jetski/wave-runner (had it going about 70mph/113kmph this past week on a lake in northern Wisconsin only our machine is gas powered)! That battery speed though, was super fast!! And looked SOOO FUNNN!!! Loved the comparison of all the motors. Nikki- "My cheeks are starting to hurt!" (from smiling so much!) 🤩👍
One thing that the Zerojet has over all the other options you looked at is its battery chemistry. It has LiFePo4 cells, not NMC like the others. NMC cells have only a fraction of the life span of LiFePo4 and even more important on a boat is the safety issue. If something goes wrong with NMC cells, then you have a huge problem on your hands.
The ePropulsion uses LFP too, hence why they're so heavy versus the Motoskiff's NMC.
lipo's can also do bad things if youre not careful. still the better battery but not quite there yet.
@@pezpengy9308 LiFePo4 aren't lipo's...
I really really like the flat sides of that dinghy a lot. It's so cool that they let you test so many. Love that.
I'm a zerojet fan! Fun and practical✌️💜
I've been using an epropultion spirit 1 on a wooden dinghy (seahopper scamp) for a couple seasons as a full time live aboard on a fully electric monohull. It has been great, so much better.
The jet looks like a blast!
Bad thing about jet impellers are high wear parts that need to be replaced more often as a bit of wear with significantly decrease your efficiency and thus range...from what I'm told.
That's awesome you did that - so impressed with how far this genre has come! Many thanks!
the jet system seems to be the most promising out of all the e-tenders I've looked into
That looked like a lot of fun and I learned a lot also. Thank you for sharing
We went electric a couple of years ago and would never go back. After a false start with an electric outboard that wasn’t any good we found the ePropulsion Spirt Evo and it’s been amazing for the last 18 months. We got it when we were in Venice which was good as a lot of areas are starting to ban petrol engines (I’m sure there will be more of that around the world, something to bear in mind) we had a problem with it in Turkey this year but they fixed it within a week, they have brilliant worldwide service ( they actually sent us a new unit!) something else to bear in mind. Loving the OC dinghy and that amazing jet pack, exciting times! Great review guys.
your journey is an inspiration. I've always dreamed of having an electric yacht.. seeing you making it into a reality is just 😍
Amazing that you got to test all those prototypes, super fun to watch and does indeed make me hopeful that my future tender will be electric! Thanks so much for making these videos guys!
I am always so pleased to welcome you guys into our home and was wondering how effective a hydrofoil configuration a bit like those boards you rode could be, then even that concept made a brief appearance!😃
Like all the others who say so I love what you do and how you do it so thanks very much guys, for providing some pleasantly anticipated and consistently interesting, entertaining brightness every week!👍
This is exactly what we have been wanting to see. The electric outboard motors test was great. We have to vote for the zero jet. that looked like you two were having a blast. Thank you for sharing this info. Maybe in 2 years the price will be more affordable.
So much time and work in these videos. I am a land lubber in the middle of the USA but I appreciate all of your hard work. Cant wait to see what you get and how it looks on your new boat!
The Jet drive looks like so much fun!
You probably already thought about this. Is there a marine grade portable solar charger to take with the dinghy? You could let it charge while you’re on shore
e propulsion have a solar panel option, I think !! at 3 knots its almost even input output, great for fishing during the day
Electric engine is ten hours charge time, for two to three hours max use time, even with solar. You need AT LEAST one spare battery. I just got Torqueedo 1103CL - good in calm water which is not common in good sailing weather! - but its great to start and be sure it will start!!!!
thank you for taking electric dinghy propulsion off my to do/consider list. As I expected we are years away from e-solutions.
Really interesting and useful. Many thanks
TORQEEDO!!!!!!! So many good new options. You should really check them out!
Torqeedo is a great option with superior battery technology. Their 5000 Wh batteries are are waterproof, smart and weigh around 80 pounds.
@@sun2prop I'm a dealer for Torqeedo. Love the product so I put it in my lineup. For many of the reasons you said.
Some very cool options there. The zerojet looks like a hoot. Problem is, you folks beach your tender a lot. With no way to cover the intake, you end up sucking a lot of sand through your jet impeller. Though it is intended to be beached, having run a jet into shallow beaches a ton, I just see maintenance headaches ahead. Hint: when you kick it sideways, do a half-reverse on the deflector bucket, it will keep the rotation going. :-)
Agree: Salad shooters (jets) are fun, but not particularly reliable and beaches are their nemesis.
also wonder how they do with alot of seaweed in the water.
The worst thing thing that happens to a jet driven boat is a lily pad. Haven't seen you both go through a lily pond lately.
@@halburtonwarrington-minge3434 mulch floating in the water is a fun time as well, speaking from experience ☺️
OMG lilly pad pond...i can picture it in my head us tearing through and frogs jumping out of the way 🤣
Thanks for the informative comparison!
I saw the your NEW boat!! She is beautiful and I absolutely love her color!! I will NOT say how I saw it, because I do NOT want to spoil it for you, but I am sure that you can make an educated guess. 😉 It was on another channel ever so briefly. I cannot wait for the Official Reveal!!!
Zerojet takes the game to another dimension. You just have to get it. It will pay itself off, no doubt.
wow, the zero jet looks impressive
I've been thinking about this for a few years now. I'm glad to see it finally coming to fruition.
That Zerojet looked way too fun :)
Can already picture the zero jet hanging on the new boat
Is the jet more anti-theft since it’s built into the boat? Could be a big plus. 🤔. Hate to spend so much on electric drive just to have it stolen.
Thanks guys, so informative
awesome analysis.. jetboat for the Wynn!
I am wondering, how much of the desire for electric dinghy is for the show you produce? For the optics. If I were voyaging I would want range and weight capacity. Load one of these electrics down with a month or so of stuff to transport and I just don't see it.
Agreed, the specifications don't meet the performance requirements.
Just out of curiosity lol no pun intended. How long does it take to charge each one of those, I don’t think I heard you guys mention it? How pricey is that jet boat. I really liked that one.
To be honest i doubt the charging will pose too much of a problem as the the boat will spend a lot of its time on charge from their new solar system.
@@hogwild5844 the Torqueedo is 10 hours - most batteries are as they charge 10% per hour optimally. You need spare batteries.
Jet boat was 18k
@Graham Cook indeed
@Graham Cook That will be a long wait til spring down under.
Lots of testing and 3 good possibilities to choose from. That really looks like a lot of fun to test the various skiffs and it looks like your criteria keeps you focused on what works for your new boat. However, from a purely looks-really-fun perspective, the ZeroJet testing looked like it got you to smile so much that it hurt. Looking forward to seeing what you end up with. BTW: We finally got our storage facility consolidation finished and are officially at our first campground that starts our 2+ year adventure being full-time in an RV. Staying in hotels from May 16th until July 6th got old quickly, not to mention it was awfully expensive. I wouldn't call us nomads, but we're finally free to move about based on our own discretion and interests for the first time in 37+ years of our married life. We're still looking for a CZcams name before we start filming our adventures.
Fascinating!! invaluable research professors!!
Nice video and, in part, shows our experience with an e-outboard.
For about four years now, we have had the E-propulsion spirit 1.0. Initially as an outboard for an 18-foot wooden sailboat, now as the outboard driving the tender of Slàinte, our Beneteau Oceanis 40.
After switching from Gas to E, we were pleased to have eliminated the gas smell and noise. It's a dream to glide quietly up a tributary of the Chesapeake Bay in the early morning and watch wildlife without the noise of a gas engine.
However, there are downsides, and you already named them. At some point, we wished to extend range and speed, but battery cost and system weight are outright prohibitives for our 310 Zodiac.
There is another vital point to consider, especially for those looking forward to leaving "civilization" as you did in the past. If one of those modern electric motors fails, it will be hard to get them repaired, depending on where in the world that happens.
Our E-Propulsion battery dropped on a wooden deck from a couple of inches, and the lower housing part broke (almost shattered in pieces). No replacement part was available from E-Propulsion, and repair was not considered an option; instead, we were suggested buying a whole new battery. Finally, we were lucky to buy a used part from a defective battery and repair it ourselves. If that had happened somewhere away from the beaten path, it would have rendered the motor unusable. We like our E-Propulsion, no question, but service and repairability are something to consider. Sorry for that lengthy comment...😔
wríñg
Just curious as to the type of watch you are using to track your speed?
OR - Buy the least expensive boat/motor (gas) solution now and watch as technology advances. You will have the HH44 ultimate toy to entertain you (and all of us) that will overshadow a fancy dingy : )
get the zerojet for long range and the motoskiff is so light you can stow it for backup.
Not only is the jet fast,no engine off the back that someone could walk away with. The jet also gets points for cool factor
And it won't get banged up on rocks or wrap up a mooring line.
Skimming over shallow reefs a major plus
That jetboat is awesome! Reminds me of our little Fling jetboat we have on the lake here in MN. You can do the same thing and 360 at high speed, we have yet to flip it, but try hard not to! 😆

Great video and one of your best imo! Well done for the effort it must have taken by yourselves and the ppl who supplied the motors.
Awesome vid guys! Electric is so where it's at these days that jet looked like a blast. , I'm planning on doing a conversion on an old ski boat from a yahama to an E outboard, looking at elco.
We've heard lots of good things about the Elco. Our friend we filmed in Tonga made his boat with an Elco. The vid and his boat are called Escape Pod in case you want to see it on his boat :)
@@gonewiththewynns awesome thanks!

Wow the jet engine is super impressive that is an electric engine I'd definitely consider
Yeah, for me personally, the only real dinghy option for electric would be at least a 5-10kw motor and with external batteries, which of course, increases the weight of the dinghy. Oddly, the smaller the craft, the harder it is to go electric if you want that gasoline level of performance and range. One creative option would be making a bimini with one or two flexible solar panels to act as a range extender, lol. If you made a point of getting as high efficiency as possible ($$) it might just mean the difference between go and no-go if you can fit a couple hundred watts on.
absolutely! PEROVSKITE solar cells are making flexible film a viable alternative performance and especially weight-wise. Soon available on the market and especially for Bimini's 😃.

That jet dinghy looked like fun! Hope to see more of that foiling dinghy
I’ve watched you for several years. You get along so well, I bet you never fight.
I like the jet drive dingy the best. It seems the most practical.
Do we have a pool going on how many comments are posted declaring that "electric propulsion is a bad idea?". Someone with better math skills than I could put together a spread between "you'll need an ICE engine in an emergency" and "lithium batteries catch on fire."
I wonder how many of them also tally the statistics with ice and regular electrical stuffs… it’s newer tech so any issues get highly publicized, yet the old stuff is old news so it’s not in the public eye. I’ve saved so much money with my ev, especially with how the prices have been this year. It’s crazy how entrenched in fossil fuels society has become.
@@It-b-Blair I'm constantly having this argument with my mother over what car she should buy. Now that plug in hybrid electrics are here, I think that's the no brainer choice. She would be mostly running around town and going to church. The hybrid part of the equation would get her over the mountain to see my nephews (a trip she takes about four times a year.). And I get that she doesn't want to sit around in Wytheville, Virginia for two hours to recharge, but she would have the hybrid drive train.
IDK, man. People are really attached to their cars.
It's true though. They spend a lot of time in very remote areas. If they have an issue with their yamaha chances are someone around is familiar with ice's and can take a look. If they have an issue with an electric/jet motor then they're sh*t out of luck
Great video...I love that last one!
Excellent video.
Thank you.
Fantastic video! So cool to see all the options in action, I really like that MotoSkiff option as a auxiliary back up. We are going with ZeroJet, and it would be cool to have a custom bracket made so you could slap the Moto on in a pinch if something were to need repaired. What are your opinions on the larger battery bank option from ZeroJet? Is it necessary is the range good enough for cruising with the single battery? That foil option could be a game changer!
Right on! You've already ordered a ZJ? We had the 2 battery system and it is necessary if you want to go the distance :)
@@gonewiththewynns I’ve been chatting with Delcan for a while now and timing our order to be delivered to Balance in St. Francis for when our 526 Mk2 is completed in ‘24. Hoping that there are a couple of improvements in battery capacity between now and when we take delivery. Right now it’s roughly a 9 month delivery we are planning on. Only debate is if we go with the 2 battery system and live with the added weight. First world problems : )
@@kirkb3473 I placed an order from ZJ but I think the batteries are a bit weird. Heavier than necessary (I'd use NMC for a dinghy on davits; fire isn't as big a concern, it falls in the sea if it happens...) and they're 3-4x the $ of the rest of the market. Sure they have high rated amperage but they're not alone like this and SuperB is milking it with the 3-4x price. Batteries are largely a commodity now.
Hence; Zerojet, yes. SuperB battery: really not sold.
We have a Navy 3.0 with E80 on a Highfield 290CL right now and it's too heavy to be convenient, and I'll experiment making a custom NMC pack to replace the E80. That'll inform whether I order the ZJ with or without the SuperB packs.
@@AntoineGrondin very cool, thanks for the info Antoine. I’m thinking battery tech is going to rapidly advance over the next 5 years or so. Once solid state becomes a reality to consumers it’s going to make a huge difference in weight and range.
Hi @@AntoineGrondin we are glad to have you on board as our customer. If you have any questions regarding the battery, flick us an email at sales@zerojet.com :)
You deserve the Zerojet What an amazing toy/tender.
Wow. Great review of products. Manufacturers should be really happy to have their products highlighted so nicely and effectively
That was amazing to watch guys, thank you.
The only thing I don't like about going 100% Electric is lithium batteries sometimes catches on fire would hate to be at sea and catch on fire!
Lifepo4 is safe as safe as can be. It’s the lithium Ion that can catch a light. Even then they shouldn’t, I think it’s mainly the way people install these things that can be scary.
The thing I get more concerned about is lightning. We kept our starter battery lead acid so it’s separate from and BMS that will turn your batteries off.
Big car companies cheap out for mass production. You can get quality batteries with controllers to match. Keep the charge between 20-80%, and have a fault meter on every cell with an auto disconnect for the banks if one is detected. Electrical systems will catch fire when abused, and different chemistries require different care.
If it’s a phobia, you could install the batteries like a life raft under the hull with a quick disconnect and a temp system that auto-releases if a fire starts. Horrible for the oceans, but better than a whole boat being crisped.
I thought that gasoline/diesel was more flammable than lithium batteries. ;)
@@monksuu Lithium batteries are capable of spontaneous ignition and subsequent explosion from overheating. Gas/Diesel is very stable. Gas/diesel is an accelerant, that helps spread the speed of a fire, but doesn't start a fire.
Zerojet will involve a lot of rowing if it breaks and you're in the back of beyond. Can you attach an outboard to it if needs be? With the other options you could easily. But ultimately Ill stick to combustion till e-outboards become more ubiquitous, are faster and the batteries have much better energy density.
Informative video.
Tnanks
Great vid. Thank you!!!!!!
And when the next generation battery is available, it should be a simple upgrade. (Ask Zero Jet what they plan)
There is no better option currently. It is clear they were already using high Cobalt content batteries for the high C rating. Until Sulpher batteries come of age... this is as good as it gets. Wishes are nice, engineering reality is yet another thing instead.
Can there be any doubt - the ZeroJet is the way to go.
Great tests, loads more options than I thought and the last one would be what I would choose. By the by, got to see your new cat at the Miami show. Fabulous!!!
So cool!! Stoked that you love the Zero Jet so much!! Thanks for doing a review!!🙌🏼
The only big downside to electric outboard s is range, they last a couple of hours at best where a gas can last 6-8 hours on a tank (runtime)
And the batteries alone cost more than the gas outboard .

So impressed with your winding down a selection for a tender for Curiosity II... Personally I got a kick out of the zero... But am not sure about the length or the weight, or if it is a fit? Thanks again for a stellar sharing of the life your living making decisions.. Such a Class act all the way around.. Love to you Both!
the nice thing about an outboard- its universal around the world. have problems with a one off custom electric craft- well it won't be fun tracking down parts/repair on the wrong side of the ocean.
I always look forward to your videos on Sunday morning.
Keep in mind that the battery will in about 3 years be 50% of what it was. Also I like quiet and such but it is pretty nice electric if slow speed is fine. I would be afraid of going to dock for food and not having energy to get home. Also TEST the batteries for floating you will test this in real world even if you don't want to.
Using the same technology as our current electric cars they can expect about a 2.3%-4.2% loss each year in efficiency. That is of course dependent on how much they use it and their overall maintenance on the batteries themselves. If they follow the manufacturer's guidelines for maintenance and recharging they can bet on closer to the 2.3% loss. Even still you can chalk it up to the same kind of expenses they would incur over time from keeping up with fuel, oil, and maintenance of a gas powered tender.
Not with LiFePo4. None of these electric motor companies are using AGM’s anymore. Give it a year or two an no boat builder will be using AGM’s. LiGePo4 can go 100% to 5% 500 to 1500 cycles with only a 20% loss of capacity. With good management and not dropping below 30% you can get 6 years out of a battery. Relion makes a good battery but they are expensive.
The ePropulsion guarantees 3000 cycles at 80%. Usually this kind of battery will perform even better, if treated with care.
@@Michael-dh2sw the battery tech is finally starting to snowball… like it should of 10 years ago. Solid state tech is just around the corner and capacity will increase 5 fold.
At this stage of the game, it would be extremely easy and inexpensive to ask the hull manufacturer to design more structurally robust davits! One never knows what needs the future might bring.
Can't lie I have wanted to see a all around electric test like this, love it
That Zerojet looked pretty sweet
