I agree 100%. They can do these sorts of experimentation because of their success as documentarians on KZbin, and I've really enjoyed watching their channel from the start, when they experimented with the copper coating on Uma (It seems like yesterday).

@ Yes it’s amazing to see how some products work in real world conditions. They hinted at a wind 💨 power system in the future, and they were experimenting with a turbine earlier.

No sun for days. No wind for wings = depleted batteries. Now you're a bobber. Diesel motor and fuel are more reliable and less taxing on earth natural resources. Try adding up what goes into making all of the resources needed for a battery powered boat. Then how often you have to fix or replace them.

[@stopthephilosophicalzombie9017]

@@mattsuser I've seen some debate about whether the all-EV economy is all it's cracked up to be. Our grid will never be able to handle everyone having all electric vehicles and also there's the argument that hybrid vehicles are actually better overall for carbon footprint. We are also seeing the damage wind and solar farms do to wildlife, but you can't deny that fossil fuels are changing the planet for the worse also. It's a conundrum. I think more nuclear has to be part of the solution.

When you are in temperate climates all electric is a good plan. If you go back to the arctic type weather you may wish to rethink your heater.

[@geoffhigginbottom5670]

Hey guys, I occasionally skipper a 40’ monohull with twin electric motors, so have some experience manoeuvring. The props are a similar spacing to yours, possibly even wider apart as it’s a bigger boat, but still way too close to the centre line to provide the turning forces you get on a cat. We actually do the opposite, for example when turning to port, we use the port motor to push more water over the rudder, and run the stbd motor in astern to reduce boat speed and make a tighter turn. When going astern we find we can make minor course alterations using the motors to ‘pull’ the hull to port or stbd, but only really to keep her on a straight course, with long slow turns possible, but nothing close to the control a cat has with two engines very widely spaced apart. I fear you will lose a lot of manoeuvrability not having the prop in front of the rudder and may want to consider a bow thruster, similar to how boats with twin rudders have to rely on them for the same reasons.

[@antc5010]

Uma is only 36'. Bow thrusters are way OTT for berthing a vessel of this size. Dock lines and handling skills are better to adopt / develop and don't load the already hungry onboard electric systems.

[@stopthephilosophicalzombie9017]

@@antc5010 Yeah something tells me they will figure out a way to use the two props optimally for docking just fine.

[@geoffhigginbottom5670]

I agree with not normally needing a bow thruster, my own 40’ does not have one, but none of you have any experience handing a boat with twin electric motors offset from the rudder, I do and was just sharing my 4 years of experience on such a vessel - it will not handle like a cat which is what they are expecting, and they will need to do the opposite as I explained . The boat I skipper with electric motors does also not have a bow thruster and is a nightmare to dock as a result.

[@AdamC5013]

@@geoffhigginbottom5670interesting, thanks for the input

[@Paul-e1p8n]

I fail to see how one engine in forward and one in reverse wld not result in the boat to turn around its axis. So please tell me what happens to yours when you do so.

[@Jack-yl7cc]

6:38 For future reference, the correct tap to use on a blind hole(aka Closed-end hole) with soft material, is a spiral fluted tap. Unlike the tap that was used, a spiral fluted tap is designed to break the chips from the cut threads and lift them out of the hole(just like a normal drill bit) instead of trying to push the chips down and out of a through hole. They also make a tapered tap which aids in getting the tap(and thus the threads) started squared and true to the hole and third kind called a bottoming tap which as the name suggest, is for cutting threads down close to the bottom of the hole. These little details matter a lot more for power tapping but, it does make hand tapping a lot easier too.

[@computiNATEor]

This is great info. Copying this down, thank you!

[@johndavidwolf4239]

They were NOT a blind holes, as behind the aluminum plate, there was at least one bolt diameter of foam, plus the aluminum plate appeared to me to be no more than one bolt diameter thick for that a straight flute tap is fine.

[@francesconicoletti2547]

How do Ocean Volts work on Catamarans ? Catamarans are famous for not having keels and going fast , did the company design them to be easily damaged without forward protection ? We have seen a couple of ocean volt cats in this series so it is a valid use case.

Happy New Year UMA. Boat rebuilding looking outstanding.

[@ScubaDrew]

After moving to a catamaran and having experienced catastrophic diesel engine failure on a monohull in the past, I've always felt much safer with the redundancy. I think this is a wonderful solution for folks traveling as far off-grid as you two do! I often wonder how diesel and electric (the total system) compare in terms of failure modes and the potential for end-users to self-repair those systems. I'm certain diesel has more points of failure, but we've learned to address many or most of them, even while at sea. Electric motors seem much less likely to fail, but when they do, they feel almost unrepairable. Either way, redundancy is key and I'm excited to see this project progress!

[@dancarter482]

_Tally Ho_ is hybrid now - beautiful installation, they don't appear to be using the electric portion and haven't mentioned re-gen at all since launch. I think they'd have been in trouble without their diesel. Hybrid all the way if redundancy is the goal!

[@ScubaDrew]

@@dancarter482 the Wynns have a hybrid system and it is sooo complex. They experienced a failure mode where the charging system destroyed both starter batteries. Hybrid sounds temping but looking at the electrical systems it feels dangerously complicated when implemented.

[@NomadSurvivor]

You cannot find anything as tried , tested and reliable as todays Diesel engines. That electric system will be scrap parts in 15 years when my Beta Marine Diesel has about 1000 hours on it. With any Combustion Engine a little preventative maintenance and it will last 60+ years Easily. Look how many old diesels still plug along after being made in the 50'-80's. Detroit Diesels are the prime example. How many farmers you see riding Electric Tractors out on the Harvest ?? 😂

[@ScubaDrew]

​@@NomadSurvivor Yeah, I agree. I *want* to love hybrid and electric sailboats, I own a Tesla, so I've bought into the electric market. __However__ One thing that is 100% true about your statement is that batteries are a *consumable*. They get worse over time. They will need to be replaced. This is not such a big deal when you are talking about a couple starter batteries, but with hybrid or all electric, it is not trivial! It was wild watching sailors try and deal with Lithium fumes on a boat from an overcharged battery. Mistakes and accidents will happen, and having lots of electronics and batteries around has got to come with risks.

[@stopthephilosophicalzombie9017]

When torqueing a ring formation of bolts you want to use a star pattern just like you'd do with putting on lug nuts with a tire. Probably doesn't matter as much with this install but it's a thing. Beautiful work as usual.

[@Nilezy]

I would say it does matter as the alignment of the drive will not be the same as the measurement with the laser so the drive won't be setup as per the original aligment if the ring is high on one side (the first couple of bolts torqued) vs. the last

[@stopthephilosophicalzombie9017]

@@Nilezy Good point! I'm sure Dan will double check the alignment; now that you mention it it might even be more critical in this sort of low-torque application because it won't tend to conform to the base as much.

[@johndavidwolf4239]

For wheel lugs on a vehicle, it is tight enough to transmit the torque, both acceleration and braking without any slippage, along with not distorting the brake rotor or stretching the bolts/studs beyond yield. For this I would have first tightened to a very low torque, just enough to squeeze out the sealant from the "high spots", wait 48 hours for the sealant to harden, then torque to spec.

[@stopthephilosophicalzombie9017]

@@johndavidwolf4239 Great point. You understand the point of my post; if you don't tighten them in an opposing bolt pattern (star works as well as anything) you can end up with a pinch situation where the bolted piece doesn't sit flat/parallel.

Instead of poiring money into integrated batteries I used simple isolation detection and temperature sensing to keep things within the battery onboard BMS parameters. It doubled our capacity for cost. Would be glad to share my notes.

Apples vs Oranges. I run 4 - 200ah Lynac Lithiums in my Nomad Van. I can last for a week without sun. What they are doing is absolutely insane and a huge waste of money With Batteries they are putting over $100,000 into propulsion on a $10,000 boat.

[@tartansailor]

The more you rely on solar, the closer to the equator you need to be; Navigating the higher latitudes do not provide a lot of sun to charge batteries. On the contrary the wind generator will help up north but not much so in the south as we normally seek calm anchorages. Not planning for a backup generator is a mistake. If you are sailing 5 % of the time and spending 95% at anchor, the regen function will be of little help in the overall sailing picture. That being said I like your videos and the way you work on your project. Cheers, Richard

We installed an Allpowers r4000 on our 32 foot NAB which we stay on in winter weekends in The Netherlands. It can deliver 4000 watts and has a 3600 Wh battery inside. So with a 2000watt electric heater we can’t even warm our boat for 2 hours… It’s great for cooking, not for heating. When docked that is not a problem because there is shore power. But otherwise? … I hope you lovely people will insulate your boat like crazy. PS: we love our airfryer. no frying oil, and making ‘kaizer’ breads are perfect… Not many people seem to realize what convenience 220volt means for the modern world we live in. And what it takes to sustain our modern lifestyle. I am afraid you will need to install a heatpump system which takes heat from the surrounding SALT water under your keel… That would triple the effectiveness of your electric capacity. But still most important thing to do is INSULATE YOUR BOAT LIKE DOOMSDAY IS COMING. GOOD LUCK.

But what if they end up in the tropics? Not all of us live in / sail in cold climates.

Great video guys. Check the cap head machine screws which you used to fix down the motor flanges, two of them looked like they have not compressed the spring washers. Perhaps just the editing? or the flange is not secured properly, even if you torqued them to spec if the spring washers are not compressed this would indicate that either they have bottomed out in the hole or you have not fully threaded the internal aluminium plate. Love the idea of the twin motors. Re-gen and manoeuvring will be awesome 👍

[@geoffhinsley6913]

Just a thought . …. I didn’t see a flat washer under the spring washer. I was taught to install one between spring and surface, especially if you’re bolting a ‘soft’ material like Aluminium. Having said that, I haven’t finished watching the entire video. (Pretty much up to date with the other 400+!😊). PS What an awesome job you’re doing !

[@MarcoYolo420]

Question: Would it be better, after applying the kit, to lightly tighten the screws until the kit squeezes out evenly all around, but not completely, let it dry, unbolt the screws, then apply thread locker fluid, and tighten the screws with the prescribed torque? This way, there would still be a fair bit of kit layer between the surface and flange for better adhesive and sealing...??

[@salisbury1944]

... clever editing (as always) - very clear what you are doing seeing the glassing inside and out at the same time...

[@johndavidwolf4239]

Actually I have found resin work in cold weather can have the advantage that if you preheat that which you are applying the resin to (in this case your hull), you get a longer "pot life" while once it is applied, it hardens faster.

[@MarcoYolo420]

Are spring washers doing their job well? Grok v2 respond: Spring washers, also known as split washers or lock washers, are designed to provide a preload between the nut and the joint, which theoretically helps prevent loosening due to vibrations or thermal expansion. Here's a breakdown of how effective they are: Pros: Vibration Resistance: They can offer some resistance against loosening caused by vibrations, especially in applications where there's not much movement. Ease of Use: They are simple to install, requiring no special tools beyond what's needed for the bolt and nut themselves. Cons: Limited Effectiveness: The effectiveness of spring washers can be quite limited. Over time, they can flatten out, especially under high loads, reducing their locking capability. Potential Damage: In some cases, the sharp edge of a spring washer can dig into the surface of the bolt, nut, or the mating part, which might cause more harm than good by damaging the joint or fastener surfaces. Not Ideal for All Applications: For applications with significant dynamic loads or where secure fastening is critical (like in machinery or automotive parts), spring washers might not provide sufficient security. More advanced solutions like locking nuts, threadlockers, or double nut systems might be more appropriate. Effectiveness in Practice: Static Applications: They can work adequately in static conditions or where there's minimal vibration. Dynamic Conditions: In environments with high vibration, their performance can be less reliable compared to other anti-loosen methods. Alternatives: Nord-Lock Washers: These provide a higher level of security through a camming action, ensuring that the bolt doesn't loosen over time. Threadlockers: Chemical compounds that solidify to lock threads in place. Serrated Washers: Which grip the mating surface to resist rotation. In conclusion, while spring washers serve their purpose in certain contexts, they are not always the best solution for ensuring bolt integrity, especially in high-vibration or high-load situations. If you're in the Netherlands (NL) and dealing with such conditions, considering alternatives might be beneficial for ensuring the longevity and safety of your assemblies. If you need more specific advice or are considering a particular application, feel free to ask for more detailed recommendations.

[@ianollmann9393]

Speaking as someone with solar on my house and some power walls, if there is a question between more battery and more generation, the right choice is more generation. Solar is nice on a sailboat, but I just don’t think that you have enough square footage to do much more that support appliances in cabin while on anchor. Wind won’t help much, but might annoy you with noise and may yield some sponsorship dollars. Regen is what is going to get those batteries charged if there is wind to drive the boat at speed. A catamaran or trimaran would have a lot more square footage for solar and the speed for regen.

Unfortunately, widespread availability to the general public may be limited, but worth the wait.

I like your architectural approach to boat construction ❤

[@davidlansky3904]

Love your channel. I’m on a similar page with a small Farrier trimaran, moving to all-electric with a torqeedo outboard (thought about twin outboards), induction burner, sailing/rowing dinghy. Batteries from solidstatemarine are mighty tempting (but $$$). Key to making this work is good sailing performance and avoiding tight schedules.

god damn, loving the camera and post prod editing Kika and Dan! looks fab

Very exciting, looking forward to seeing Uma 2.0 in action.

I would keep the Wood Heater as a backup. Fire has been reliable for thousands of years. :)

[@bryan314]

not to mention the fact that a fire warms the soul as well as the body when it's cold outside.

[@antc5010]

The practicality of wood burners on yachts requires storage or regular shore visits to stock up on wood. And, drift wood is often wet and salty... not good for the burner's longevity.

[@francesconicoletti2547]

@@antc5010the burner is also a heavy lump of metal. It counts towards the mass budget of the boat. If it’s there “ just in case” perhaps that mass budget should go into something that provides more useful extra redundancy like say more batteries, or bigger solar panels.

Cooking with induction and 2kw is really Enough 😉 exemple : 300 W enough for Pasta.Unless you want to sear a rib steak at 3.5 kwatts.

the thing about the way you're designing your power/propulsion system is that you are free to do basically whatever you want with it. with solar and TWO props regenerating into the batteries you could probably run a 12/24V aircon unit on the regular most days on an active sail. if you decide to add a genset later because you'll be going into cold/cloudy/calm regions and want to make sure you'll have the power for electric heat, the extra work involved is basically... nothing. all you need is the generator, hooked up to your batteries. done. I'm sure you'll have a socket for shore power; could hook up to that or just buy some heavy-duty cables that can handle the amps in DC if you want to forgo AC/DC conversion. if it were me and I were building in the Mediterranean like this, hell yeah I would forget the genset for now, you can always add one later if you need it.

Very nice episode,, getting excited for more.
