Ep 4: Selling the Engine and Why Electric

[@jesper1406]

No wonder you sold it fast. Bukh diesels are some of the world's most reliable engines produced in Denmark. Being in a lifeboat it's basically new. Going electric, especially for sailing canals is absolutely perfect...

[@LivingOnALifeboat]

Yes, one of the best marine engines in the world! If we were looking for a marine diesel in the future, we'd probably look for a Bukh (the irony). But as you say, for the canals electric will--we hope--be great...

[@ethanbunch3274]

I just got out of diesel school and it joys me to see that little motor getting used for a good purpose. I've also looked into electric for RV or houseboat conversions and there's some big advantages. Another conversion of these had massive solar panels that were 900 watts so you could easily recharge those without having to stop for fuel if you had diesel.

[@ItchiusScrotus]

12kw is some serious torque with that motor.

[@ItchiusScrotus]

Extremely keen for the next update on the solar and battery system

[@0xKruzr]

Every time I see a story about an electric conversion it occurs to me that those heavy lithium batteries make excellent ballast for vessels like lifeboats that are meant to be heavily weighed down by having lots of people in them. Two people instead of sixty = that hull is liable to bob around and be a really wild ride. Without the weight of the diesel engine especially, you have weight allowance for a HUGE amount of power storage in there. Excited to see where this goes!

[@LivingOnALifeboat]

Thanks! Yes we have added almost 2000 pounds in batteries and have been able to build things without having to worry about weight as we need as much weight as we can get!

[@DominicNSX]

Great choice of propulsion! LiIon batteries are actually much cheaper than AGM because they have twice as much available power (can be discharged to 0 versus 50%) and last 3-4 times longer. With enough solar panels, make sure you cover the entire boat with overhang even, you should be able to power the boat for many hours per day. You will be spending most of the time in anchorages anyway. You may not even need a portable generator if willing to spend a bit more time in an anchorage to recharge😉

[@andeefoster9568]

I just caught up on your videos and its really coming along!

[@LivingOnALifeboat]

Thanks very much!

[@vnrkk]

Really exciting project and the ev conversion really sold it for me! Really curious to see what type of solar setup you'll end up with to keep your home topped up :).

[@LivingOnALifeboat]

Thanks! The area we are in has many marinas we get reciprocals at plus we will have between 1500-2000 watts of solar in the end. We are also planning to have a small diesel generator for emergency use when there is no sun or marinas to use. Most trips we take are under 30 NM per day

[@spiritnsage]

Now is the time to add a bow thruster - use a old trouling motor - can be wired easy for reverse/port/starboard - some pvc pipe - you will be so glad you did as you wil be catching so much wind broadside - people will flip when you dock agenest the wind

[@MrSychnant]

Good idea.

[@briansmythe3219]

Yes thats a verry good idear , Especially the bit about the wind pushing it sideways , There is virtually no draught and the Bottom is flat

[@SepulvedaBoulevard]

Awesome idea! Best wishes and good luck with your project. We have these boats on the ships I work in, and I have often wondered about conversion. Will be watching!😀⚓

[@6226superhurricane]

lol that old guy seen you coming. made out like a bandit an almost new diesel engine that'll still be running long after you've gone through thousands and thousands of dollars worth of batteries and motors. and the icing on the cake was when he scored the ready made fibreglass laminate for his projects, he's probably building a freshwater tank or battery box out of it as we speak.

[@LivingOnALifeboat]

I do hope he loves the engine, it wasn’t what we wanted and we sold it for pretty much what we paid for the boat. Batteries will be an adventure but lots of electric vehicles run thousands of hours off the same batteries. If you make sure you care for them correctly. Every year battery technology is getting drastically better so in 5-10 years when we are ready for new batteries it will be interesting to see what exists. As for Motor life I’m unsure where you are getting your information but as a Machinist I run many machines with large electric motors similar to our motor and currently I am running a machine that has 91,562 hours on its electric motor with never a problem. You will be hard pressed to find any combustion engine that has that many hours on it.

Great to see the update! And thanks for the thorough explanation of your thought process behind the electric engine choice. I totally agree that there’s not finer moment on a sailboat than when the the sails are full and you kill the engine! So, if you are going to insist on having a power boat (that’s a whole other debate - lol) then a quiet one is definitely the way to go!

[@ronaldharris6569]

I'm glad you chose a second engine to backup your electric power, power to push through current is important put in lots of panels a good array with lithium batteries is the way to go,possibly eliminating the need for a diesel generator

[@Superfandangoo]

Being these lifesavers are very well designed and engineered for upright buoyancy you may want to find out about adding ballast and whether it would be needed in certain areas after removing weight in those areas or you may find yourselves steering a cork so to speak. Good luck

[@jurassicchrist]

Batteries are heavy

[@Superfandangoo]

@@jurassicchrist hmm 10kg to 150kg, the weight/ballast is for water displacement/draft stops boats from turning upside down as sailboats will have lead or cast iron keels when designed the weight is put in certain placements. These boats have a range of 300 miles of diesel with 35 plus passengers, making it even lighter isn’t great in rough seas not so good, it’s a plastic bottle rolling about

[@Superfandangoo]

kzbin.info/www/bejne/haLGi2yafJuFa6M

[@LivingOnALifeboat]

Yes, we are adding weight--right now through the build, but not opposed to adding straight ballast if we get out there and find we need it, some lifeboat conversions have done that but others haven't needed to.

[@visionontv]

[@restlessperson5258]

Thank you for sharing.

[@jlamar362]

Don't forget to calculate the weight you gave up, from the diesel, so your lifeboat stays in the same trim. You can adjust several things, including ballast, water and fuel tanks, but you need to account for the difference in weight, low in the hull, so she doesn't become more likely to roll a lot in rough weather... Just my thoughts. Enjoy, and keep up with your plan! I'm enjoying watching.

[@bookman106]

Remember, electric is going to require heavy batteries, so that will probably take care of the ballast issue.

[@jlamar362]

@@bookman106 yes, it will help, but depending on the chosen batteries, the energy density of lithium is better than lead acid, ad well as lighter in weight, so I thought I would add a comment about weight, so that if the comments are read, they might think about weight and placement of tanks, to replace the weight lost from the engine change. I didn't want the weight difference to cause instability, a rough ride, or worse, turning turtle in a storm, when a bit of for thought could minimize the problem. (I always try to plan for the worst, think of anything I change, to make the problem less. )

[@JonathanCandor]

Been waiting for this video

[@karlheinzvansteen5748]

cool idea and i hope you make it work. You will need to basically cover the boat with solar panels and think about a stand with wind generator both fore and aft to harness as much power as possible. A really big battery bank is of course needed, someone mentioned LION batteries and yes a dozen of those and your power controllers will give you a bit of range I would think. Your probably not going to have much range though regardless.

[@kranzonguam]

Sounds like good choices! You've obviously thought it through thoroughly! Stay safe and have fun!

[@simongee5879]

Bravo... excellent choice. I recently built a 35' sailboat. launched 6 years ago. I was initially thrilled to install a brand new 3 cylinder diesel. When it came to hooking up all the systems,,, ie filters , water separators, lift pump, wet exhaust etc. etc., I decided to leave it till later in the build. . In the meantime I discovered electric propulsion. It took a whole day and a system of A frames and come alongs to drag the reluctant leviathan out of it's lair , up the hatch and over the side. By contrast I put the electric in a shopping bag and walked up the ramp. I enjoy the quiet, the lack of vibration and exhaust and would never go back to diesel. At this time of year, boaters are checking over their motors, changing filters , checking antifreeze, zincs etc... as usual I'm wondering if I should be doing something??

[@LivingOnALifeboat]

Thanks! Yes it will be very nice to have the electric motor in and running. We are looking forward to silently motoring along!

[@nolandmailhos8992]

I have run into so many problems just using electricity as for poulsen. Biggest problem is battery power. And distribution. Solar panels and when turbines are great. I do suggest you have a generator as backup. Keyword is triple redundancy.

[@NormanPaul]

Have you thought about adding a wind turbine (or two) for additional electricity?

[@LivingOnALifeboat]

We have, though there's not a lot of wind up here, especially in the summer. I know there are efficient ones which do tick over in a few knots, but we're going to play it by ear a little bit. Definitely not ruled out.

[@NormanPaul]

I had both solar and wind on my greenhouse in colorado. Solar did most of the work of charging the batteries but when it was stormy and no good solar the wind was usually up and I would get a charge that way. Also more wind at night and that helped slow the battery draw down overnight. In your case I think it would help when you are out in open seas. What you are doing in cool, looking forward to seeing the electric drive working.

[@Atlantismonkey40]

It’s a different approach to be responding to YOUR build . I think you should do what you feel is best. Adjust as you go. You hit the nail on the head, when you said you’re wanting to be Unique. In the end. Be safe and happy journeys.

I am thinking going with a lifeboat because it's last ship that can be sunken. I have done research all the other expensive boat. It doesn't matter it cost a million dollars. They are sink able. There's 2 reasons I love going with the electric engine. The first is free fuel. The second is it is easier to switch out in middle of the ocean. There's less parts to worried about.

I understand the electric and respect it, though i would had tried to find a way to make the diesel as a oh shit out of juice back up when it all hits the fan.

[@user-zj2mb3sp3x]

when you lookup these lifeboats their engines output 20kw to push them 6knots. 20kw continuous output seems more fitting.

Yes that is pretty close to our plan. We are not sure of having a wind generator yet especially for our location as we get almost no wind

[@AndrzejSQ9PKW]

@@LivingOnALifeboat If there is no wind, so there is not reason to have one. What battery voltage are you going to operate? I'm really interested in hybrid propulsion system on boats. New types of batteries can provide much more energy density than old ones. So this way of powered boats is open like never. I hope you will have real fun with it.

[@LivingOnALifeboat]

At the moment we are going 48v but our motor can be run at 72v or 96v as well. It is a lot safer to stick with 48v but if we need to we can go higher.

[@AndrzejSQ9PKW]

@@LivingOnALifeboat I see a lot of people hate idea of electric boat. I love it. Especially that hybrid diesel/electric can be much quieter than traditional direct drive diesel propulsion. Have you think about battery type? Lead acid, liion, lifepo4 or other type? That's nice that you have wide range of voltage to power yours engine.

[@lemonadecitrus4764]

You really need redunduncy in your main motor because during the time that you are about to approach a pier or some mooring area and your motor stop working then you are endanger of colliding not unless you got a backup that you can immediately start and manuever your boat. And steering motor if you got one they never put a protection to it like fuse or breaker. The motor will work "till death" to prevent you from collision if possible.🙂

IF I may, in your research vis-a-vis battery banks, solar and the entire onboard electrical system of Luja, I urge you to think of her like a road-based RV, but concentrate upon the internal and electrical systems.

[@veiledrecalcitrance4314]

From what I’ve heard about the diesel motors in those life boats is that they’re very slow, like, extremely slow, if that diesel isn’t going to push that boat very well, I’m wondering how well an electric motor will actually function on a boat that unwieldy. The great thing is those life boats are like Boston Whalers, you can cut it in half and both halfs will still float, plus they right themselves if they roll, you just won’t be going anywhere very quickly

[@LivingOnALifeboat]

Most displacement hulls are constrained by waterline no matter what is powering them. Her hull speed is around 7kts no matter what's powering her, but I expect we'll cruise more slowly than that, which is just fine with us--we come from sailing and are used to that slow boat life :)

[@skysara]

hi what kind of motor and driver did you use?

[@LivingOnALifeboat]

We have the 18kw sailboat kit from thunderstruck motors. We are running it for now at 48v so it will only be a 12kw motor. Which if all the experts are correct is about twice as much power as we need to be able to push us at hull speed. We should be in the water this summer to have real world numbers!

[@johnfleury5430]

Going electric! You mean the money pit starting

[@Baddad36]

Unlike a car where the using of fuel means loss in dead weight which equates to better fuel economy, in a boat it means increasing bouancy. A shift to electric is a good idea. Plus it'll be very much more reliable. Not sure about the range though.

[@ruialves3155]

Hi Guys It is the first time I see your videos and I like it very much. I am looking forward to the transformation on a electrical boat. I would like to know how you choose the power of the electrical boat ? What are the parameters you analyse before your decision about the power ? Thanks for the videos

[@LivingOnALifeboat]

Do you mean the size of the motor (12kw)? We got a Thunderstruck EV motor and used a combination of their website, talking to them directly, their customer reviews, and other online groups, forums, resources, in-person conversations with people who have converted, etc. to decide what we wanted. This one is 48v but can be re-wired at 72v to run at 18kw so if we need to increase the power we can. We looked at our estimated finished weight, our waterline/theoretical hull speed, and other similar size boats and experiences.

[@SenatorPerry]

There is so much disinformation on the electric components and so many negative opinions/thoughts. Don't let the youtubers bother you. $120 US per kWh battery + Thunderstruck's system + flexible solar panels split with an MPPT per side (one per port, one per starboard, one per top) + diesel with battery charger (Victron unit) and you have a system that will give you diversity of power. 3000+ cycles (~8.2 years) at an 80% discharge rate is better than 10,000 hours (417 days) on a diesel. The only thing I would offer up is that you may want to consider mounting a wind turbine aft so that when you are at anchor the drag created will force the the boat into the wind and you can get a bit of extra power. Really looking forward to your future videos...

[@user-zj2mb3sp3x]

what batteries would you run? how many kWh pack would you recommend? what battery management system would you recommend? what system have you gotten 3000+ cycles at 80% discharge from?

[@SenatorPerry]

@@user-zj2mb3sp3x Sorry for the delay. The attached spreadsheet, if it works, shows you some research a did a few weeks ago listing the prices. The compromise is that this is for a 100 kWh battery and you would need to do your own legwork on a BMS for each situation. I have Fiat 500e batteries from a salvaged car with low miles. I have the packs set in parallel with each battery having a balancer (6S JW balancer) and a Daly BMS (lithium ion) hooked to a bus bar. The advantage is that the more batteries in Parallel you would tend to pull less depth of discharge. For example, if you have a 5 kWh pack then pulling 4 kWh would be 80%. Have two batteries in parallel with a total capacity of 10 kWh pulling on 5 kWh would be a 50% depth of discharge. The life cycles increases with a reduction of depth of discharge. This is relevant later in this post. The lifepo4 batteries listed on the spreadsheet mostly have 4000 cycles listing. Others are used and grade b/c or salvage grade batteries with less cycles left. Some are heavier than others. For Luja they have a limited space to place the batteries in the lowest locations so they may have used a different factor and more weight lower probably helps the water ride characteristics. And to complete this book of a post, I run two different settings on my batteries. One is a 60% capacity cycle based on voltage ranges. This is my day to day load and I hope to get around 10 years of life out of the batteries. During an emergency I can change the profile to a 90% voltage capacity cycle so that we can trade the life of the batteries for more power in the short term. Unfortunately we have had to do this twice. Again, you have to do your own research and I am not an expert. Good luck if you decide to follow this path. For my golf cart I also switched to salvaged BMW lithium batteries and have found the lack of maintenance, lower weight, and other advantages outweigh any of the disadvantages. docs.google.com/spreadsheets/d/1hSxb1sVnX1A_kj28jn2Z8Tj8EhOq2KyiahSRzBwj6i4/edit?usp=sharing

Hi 🙋‍♀️ Matt

[@josephpadula2283]

Unless you are rich stick with proven Lead acid batteries like those used in off grid solar homes. The boat was designed for a heavy engine and full fuel tanks. Use the batteries to get the same weight distribution. Do not pay the premium for the KW -hr/ kg of lithium when it is not an electric vehicle. You can not afford enough lithium batteries and lead acid batteries are very recyclable!

[@user-zj2mb3sp3x]

how many kWh of lead acid do you think they could fit in there? In my experience lead acid, isnt cheaper than lithium from salvage cars. For example a 100kwh tesla pack is $10,000 ($100/kwh) a chevy volt pack is $2500 for 18kwh ($140/kwh). a 12V 100AH lead acid (which you can only pull 600wh from despite being 1.2kwh large) cost at least $100 if not significantly more depending on the brand. Obviously the lithium is more dangerous and a fire risk if not done right. I do wonder can they fit 100 Lead acid batteries down there??? It would make the battery management alot less expensive thats for sure, and physically it would be simpler and less work no doubt.

@@jb-xc4oh What will you do when an internal combustion engine decides to go up in flames because of an oil or fuel leak? Gas is flammable and explosive, diesel is explosive under right conditions, oil is flammable. Moreover, Lead acid batteries also are flammable and have a large SDS (safety data sheet). As long as lithium is treated properly and managed properly with a functioning BMS system, they don't catch fire for no reason.

@@user-zj2mb3sp3x You sure are stretching it, even wood and paper are flammable, ever see a house burn down. Gasoline and diesel do not spontaneously combust for no apparent reason......I've seen many videos of cars even buses bursting into flames from a failed battery pack, within seconds you have a raging inferno. No thanks, especially not in a boat nor any kind of aircraft.

Enjoying your videos so far except for that annoying music and having to turn it down and up to save my ears is a bit too much. Keep the videos coming though. thanks.

745.7 watts = 1 horsepower. 12kw = 15.83 horsepower.

[@LivingOnALifeboat]

This Motor is rated at 12kw to push a boat that displaces 14k pounds to hull speed our boat will be closer to 10k pounds. If needed this motor will run at 72v which makes this motor 18kw which they suggest for a 25k pound boat. Electric has way more torque than a Diesel engine.

[@GlenCychosz]

​@@LivingOnALifeboat What do you estimate the top speed will be and will the motor over heat? I hope wind is not a problem.

[@LivingOnALifeboat]

Hull speed is around 6 knots. We are hoping to cruise at 4 knots (This is very similar to our previous boat we had for years before this one) The motor we have is water cooled. It should be drawing around 50amps at this speed (from reading other reviews on various boats) it can run at 250 amps continuously and peak at 550amps so we are nowhere near its top end. Our generator will put 50 amps back into the batteries if we are running it, so if we need to we can push harder without draining the batteries as much. We will definitely need to pay attention to things like currents in the area but we had to passage plan with our sailboat too.

[@axelSixtySix]

Well, I've nothing against electric power itself, and we must know exactly what electric power is all about. The argument "no emission" during use is true. But it is also a bit short because you must consider the whole life of your system, from production to its end of life, as it is said on the video. There's two weak points of electric power. First, an electric system, from panels to batteries, contains a lot of rare materials, like copper, rare earth magnets, cadmium, lithium, gold...There's a lot of emissions and pollution to get and transform that materials, so it ain't environment friendly. Definitely. Second, a solar panel will work fine probably 10 to 15 years, then its power capacity will go down from day to day. It can't be recycled, except the frame and wires. So do lithium batteries, and batteries in general, with an average estimated life of 8 years for the best ones. To separate the raw materials require a lot of energy, and you only get back not very useful degraded materials. On ly 20% of the components of the batteries are valuable once recycled. Last, a full solar power is not sustainable. You want a generator on boad. That's a safety feature and the sun is not always shining when you want it to. For people concerned by the environment, the best path is to buy used, and to make it last as long as possible. The energy used by a propulsion system comes later. A 60 years old diesel is still better than a brand new electric motor for the environment. That's the mankind endless production which is highly degrading : throw away, replace for new, etc. Alas, any man action pollutes :/

[@LivingOnALifeboat]

It's a complicated situation for sure, and I only touched on it very very briefly, of course, but you have a lot of good points. Lots to think about and a lot of choices that probably have no hard and fast yes/no dichotomy.

[@iversonjcameron]

Nope.....diesel always....maybe electric motor just to cruise on a no wave day and thats rare

[@billjones261]

MUSIC IS WAY TOO LOUD

[@basedcommodore]

You left out the most important part and that's how you install the electric motor I mean everybody knows how to get a motor out it's getting the differently shaped electric motor mounted and hooking up the drive shaft that's the hard part and you didn't show any of that

[@LivingOnALifeboat]

We will, but there were a ton of other jobs to do between A and B!

[@basedcommodore]

@@LivingOnALifeboat oh thank god... yes it is a serious feat of engineering. I think I am going to keep my diesel motor in place and add electrical motors on the sides as pontoon type stabilizers. My FF but has davits and steel guides on the sides that I can probably use to bolt the mon with.

[@MyllerSWE]

Electric makes it open for a fulecell in the future instead of batteries and use solar power for making hydrogen!

[@curtstacy779]

You do realize a diesel generator is a diesel motor right? you just sold your nice diesel motor with way more horsepower than your electric motor and diesel generator could ever do just to go back to diesel? all you needed was a larger alternator or generator mounted on it to charge your batteries. and to keep it quiet just put the engine covers on it. of course it's loud with no covers. At least you know you are not going very far with just electric. now I would just worry about getting out a river when the tide is coming in. thank god you are not looking into ocean travel of any kind.

[@mattpalmer5890]

I think the point is Curt is that a diesel generator will be a backup. It won't be the primary form of propulsion. What I am really enjoying about Dani and Toryn's project is that they are being brave and bold but are clearly not naive. Obviously battery power has some limitations but it has real benefits too - benefits that clearly appeal to these guys. So I think Dani and Toryn should be applauded. Firstly for their commitment and secondly for their courage to share their plans and personal experiences despite knowing not everyone will agree. Thanks Dani and Toryn for allowing us to come with you on this journey and benefit from your experience.

3000+ cycles (~8.2 years) at an 80% discharge rate is better than 10,000 hours (417 days) on a diesel. Those numbers per @SenatorPerry

[@user-zj2mb3sp3x]

@@andeefoster9568 electric conversions arent cheap. the moment they said their electric conversion was cheap, was the moment i knew they didnt know what was involved in an electric build, having completed multiple ev builds myself. They arent cheap. And if they think they're going to directly drive a propeller from solar power, they're in for a rude awakening, that concept will work on a kayak with 1000W of solar. This phat boat needs 10kw+ to move. They arent going to have a 10kw solar array thats just physically too large for this size boat. so a battery pack with 90-100kwH of energy would work perfect, but thats not cheap. Thats $10,000 or more. so a generator could be used to make this thing similar to a locomotive, a generator creating power, powering electric motors, but that generator wont be cheap either. all of this build is feasible, but not cheap!
