Ahoy guys, so excited for you! So I did some calculations a while ago based on our electric cooking. We got rid of propane 5 years ago and went with induction stove and electric convection oven, along with a electric kettle for tea and coffee. Averaged over a 30 day period we use about 60AH @ 24V, so approx 1.5 KWH for cooking per day. For the electric kettle , assuming it's 2KW (most are close to this) to heat up 500ML of water takes about 2 mins. 2/60 = .033H X 2KW = .07 KWH each time you use the kettle to boil 500ML so it's pretty minor. We have a 9.6KWH Lithium bank and found this to be plenty for our needs. Hope that helps! Brian

Hi Brian! Thanks very much for the detailed real world electric-cooking power use numbers. Its very helpful!! We are just now working on the drawings for the battery boxes so we will find out how much space we have to accommodate the the 48V bank. I installed 14kW on our last boat and we’ll want much more than that to give the parallel hybrid a useful range. It looks like your cruising is going great! We’ve been enjoying your recent videos en route to the Sea of Cortez and your Sea turtle encounter :-) Paul & Sheryl

Thanks for some real world numbers! Casey is right that style of cooking/types of meals would also affect how much energy is used. For Paul and all, please remember to use kilowatt-hours to measure energy and kilowatts for power. Energy is power integrated over time, so they're not the same type of thing. Sorry to be a bit pedantic.

Hello Paul, hello Sheryl I work in the RV industry and a few weeks ago, I had the opportunity to talk to a sales guy from a Munich based company, which builds and sells compact fuel cell generators. I asked him who is buying these generators, because big solar systems are almost standard on the bigger RV‘s. And you don’t need solar and a fuel cell in parallel. His answer was astonishing: it seems to be very popular with the sailboat customers! Because solar is always compromised by weather and the shadow of the tall mast and rigging. And of course the independency from good weather, which you need to create power from solar. I think he has a point. Maybe you should also at least have a look at those fuel cells :-) Many greetings from Germany 👋

realistic e tech at sea is happening now and advances with each new installation and experience...what an exciting future

Good discussion. It could focus on two major things: transmission losses and the potential in serial diesel-electric to place the engine where-ever you want, so it gives more degrees of freedom in design. Transmission losses in mechanical couplings are so big, relatively, that the engineering world actually may prefer serial hybrid to avoid those - in very big applications like locomotives, big ships or big plants. A generator and electric motor may beat a mechanical transmission significantly. As energy is discussed, I see an inclination worldwide to not distinguish between potential energetic power (W, kW, MW, etc.) as distinct from energy consumption (kWh, MWh, J, MJ, etc). I feel we ought not confuse horsepower with miles per gallon ;) As you consider electric propulsion, I would also be curious about regenerative use of the propeller. While efficiency of internal combustion engines (ICE) is very bad, especially in smaller engines, diesel fuel has 11 kWh per liter (about 3.4 times that in a US, or 4.5 in a UK liquid gallon). On the road, for cars, "diesel" my be a dying concept now and until the huge tractor/trailer combinations are fully electric in the near future on the road only those may rely on diesel for the way it and its engines deliver power. Regular gasoline/petrol by the way holds 10 kWh per liter, about 10% less per volume. To put that into perspective: imagine an electric car with 100 kWh battery - if the ICE were 100% efficient it would need only 9 or 10 liters of fuel. Because an ICE is so inefficient it needs a lot more, say an order of magnitude almost.

I agree the regeneration of electricity using the propeller is very important. If we can get the propeller right we should be able to supply all the power we need on passages (at least on windy ones). It would be great if a propeller manufacturer would consider this in their design. Ideally there would be a Controllable Pitch Propeller. The only one I know is the Hundested which is too large.

@@DistantShoresTV - another YT channel sails wind and 100% electric. For their Svalbard excursion they bought a small ICE generator to charge their batteries. If it doesn't embarrass you when I mention them, say so, assuming you don't know them. As their sailboat is really smaller, that indicates potential. As to electrical replacement of transmission and its mechanical losses, I saw a bicycle manufacturer who replaced the gears, chain and "speeds" by a generator - motor system with electronic gear. It's been done before, but with the building blocks abundantly available, it's a lot easier.

Hi, thanks for very entertaining and informative video. I thought a lot about the difference between the parallell/serial installment. A diesel(or petrol gas, whatever) motor installed in the context of driving a generator is normally far less used in different returns per minute, different loads and challenges - the environment gets much more controlled and technically safe for the engine. That factor and the factor that besides driving the drivetrain of the boat you have the wish to have a generator might point in the direction of the serial installment.... thanks again for all your nice shows...

So much great info in this episode. A conversion to electric is an absolute must on my list. Though, knowing we will spend the bulk of our time sailing the BC coast, a serial hybrid probably makes the most sense. Just need battery costs to drop a little more!

Thank you for all the amazing videos wishing you all the best with the new boat.

Nice overview and experience sharing, thanks! We are also building a 48ft aluminum boat (seems that we are almost on the same building step) with a an arctic and later a Patagonian program. We evaluated the hybrid option(s) but one of our key UR was to keep our systems simple (as much as possible) as well as reliable and easy to maintain in remote places, so we went with diesel engine only from a prop standpoint.

Very informative tx

Look at combined heat and PV panels they are more efficient PV operation and can help pre heat your water... This year the first Na Ion batteries are comming to the market.. Regeneration power under sail is a huge plus.. sailing Uma soon discovered that in northern climbs and night sailing. You might also want to look at the work of a couple of dutch lads on a large classic style monohull using series power. Presented by a Dutch sailing couple. With two young children . Windelo are building their Eco friendly basalt fiber hulled cats with hybrid systems. And now major French monohull constructors have launched electrical hybrid systems in their latest products. Ditching the direct diesel engine Option allows a bit more efficiency and a lot of wt saving..as Rotary and other more compact lighter and constant speed efficient motors can be used for the generator tech. Imagine a motor that weighs perhaps sub 80 lb and perhapse small enough to fit in the space of a jerry can.

Extra installation care needs to be taken with the stray current in an aluminum boat while running a Hybrid electric motor. Years ago, the German manufacturer of the Distancia 60 built-in fiberglass had a generator running an electric motor advertised. When I sailed her in La Palma, I found they removed them to Volvo diesel motors because of damage created by Stray currents from the e-engine they had installed. The stray current damage was done to the prop and prop shaft. Since I am an owner of a 15-meter sailboat, and I'm very sensitive to even leaving my boat at a marina pen. I had left my boat for 4 months in a marina. What happened was the anodes dissolved in a few months at a guess, and then after four months, a few pinholes leaked water into the hull because of corrosion damage because of stray currents leaking in the water from other boats connected to shore power. I will only stay at a marina for a few days at most, I have it moored on its own mooring 99 percent of the time when not sailing. Best SV Skoiern IV

I was interested to see how MJ Sailing decided to tackle the hybrid propulsion question in the new catamaran they are building. With two hulls, they plan to use a parallel hybrid drive in the port hull and a direct electric drive in the starboard (owner's) hull. That lets them put the battery bank in the starboard hull to counterbalance the weight of the diesel. Plus it means that the propulsion under the owner's stateroom will be quiet. One mode is to cruise with the port diesel directly driving the prop AND spinning the port motor to generate electricity to drive the starboard motor. Everything is 48 volt, so there are no losses from DC/DC conversion.

Yes it was great spending time with Matt & Jessica in Amsterdam last month and getting updates on their project! The parallel system they will get in their port hull will be very similar to ours.

Thank you

A parallel hybrid is probably the safest, most conservative and most reliable way to get long range from diesel and electric drive for motoring in and out of marinas, off anchor, etc. It's also more efficient since either diesel or electric motors can drive the prop directly without further losses. (This also creates 4 way redundancy in a catamaran, with 4 independent ways to motor.) That direct drive efficiency is why Priuses, etc., are parallel hybrids. A serial hybrid uses a generator to charge the battery bank or drive the propulsion motor, but creates more single points of failure. In principle this is less reliable. In practice electric motors and generators are highly efficient so the efficiency loss is probably not as large as people assume. The bigger issue is the potentially lower reliability. In principle you can use seawater sourced heat pumps for both air conditioning and water heating. Heat pumps used this way can be more than 400% efficient since they take (or put) heat energy from the ocean. So they can be highly energy efficient. (This is already pretty popular on land with ground-sourced heat pumps, sometimes incorrectly called geothermal.) I've heard that seawater exchanged boat air conditioners are significantly more efficient than air sourced air conditioners, for example. And you don't actually need to circulate, pump or plumb any seawater to to that since a liquid plate (attached to or part of the hull) can be used to exchange heat from the ocean.

Very inspiring chat. For more solar on a monohull, maybe consider having an arch with sliding panels like Mads at Sail Life has done

You're welcome James! I see you and Eva are doing great! I just watched your ORC57 test sail. Looks exciting!

I recently installed a 5 positions induction cook top of max 7400 W over 2 fases 230V at home. I had to have a larger capacity power connection for the induction cooking and it took me since 2013 to get it! Now we have used it for a couple of weeks I have a hard time to see the difference in daily electricity use before and during the use of the induction cook top. Yes it's able to use a lot of power, but only for a short while. The total amount of electricity in kWh used during the cooking session is displayed the moment I shut the cook top down. Most times it's 0.7 kWh per dinner. So you will need an inverter capable of converting enough power for the induction cook top, but it will be working only for a short time. Boiling a 0.25l of water for tea takes app 1 minute. On gas it took way longer. Boiling the same amount on gas will take 6x more energy as by induction. Induction is so efficient.

Good video. Thanks. I'm really excited by the HH cats in general and hybrid for boats. (My absolutely second thought when I got my Prius, even before I wanted to sail was, this would work great on a boat.) I always want to see all the numbers connected. (Here the 4 hours of full throttle electric motoring is both impressive and informative.) I would like to know: what's the daily on board electricity usage range of a sailing couple? (I've been through the Bahamas on a cat so I know AC is used less than one might think, so that can be a separate number. And this number/spread probably doesn't exist.) Of the 5000 watts of solar what % is likely to be 'working' in what conditions? (This practical number of course would only be realistic after months or a year of sailing.) Also, what would be the maximum practical solar array possible on a 49' mono, a 49' cat, etc.... I don't expect answers, but just as a general suggestion for future videos. It's a terrific subject. I've got some solar on my boat but haven't used it yet, instead that's where my Starlink is sitting. (Might be good to ask Casey on a boat install recommendations.) And yep, Starlink works better than marina Wifi (or a cell boost antenna/amp). And it worked all the way off the California coast around a couple of the Channel Islands (at 6.5 knots) and back to Oxnard!

Dear Paul and Sheryl, We have a 50 year old Fisher 30 North Easter, and have removed the gas for cooking for safety. Instead I installed 1000AH AMG batteries, for cooking and baking, and as a charger I use a 12/3000 Victron plus. we spend a lot of time in harbors and this way we keep the batteries charged, we don't do much sailing (anymore). I have worked as an engineer on tugs for the last 16 years and make and install everything myself. I mainly do the engineering with people who I think know a lot about it. I keep an eye on inland shipping for hybrid sailing, because they are trying to make progress in that sector, but electric sailing is now only possible if they place batteries in containers and change them every day, as on the route from Rotterdam to Rotterdam. Alphen on the Rhine. Both series and parallel hybrids have been used with tugboats, and are mainly used to sail back to the berth. it obviously has insufficient power for towing. I myself am thinking about series hybrid, when stage 5 engines are also required for pleasure craft. Greetings Lucas Mandemaker

Hybrid is the other way around as well. harvest the motion frim the props under sail, send it to the alernator-generator and store the electricity to the bateries. It will require some modifications to run fine without unneccesarily wear other stuf like the gearbox even on neutral. A set of cluches on the shaft maybe.....

Very nice video... very...

One upside of serial hybrid in a monohull with twin rudders: you can have two electric motors. That adds redundancy and manoeuvrability. Viator Explorer / Volt-at-sea uses that.

Regarding generating heat for showers etc., has anyone thought of using heat pump technology on a cruising boat? My heat pump system at home is about 30-50% cheaper than comparable natural gas systems and that is basically extracting heat from the air. Seawater is by definition above 0 (unless you are "sailing" on top of ice) even in the Arctic and so it is a reliable source of 'free-ish' heat. As for size, I understand that Tesla vehicles rely on a heat pump to provide required heat to the batteries and the passengers that is relatively compact. Just a thought.

That was a great talk, covered most of the topics. I am a huge hybrid fan. I was designing a boat to include that but realized I didn’t have enough life left to build another ferro boat so settled with a “bought” one, which sadly is not suitable for fitting a hybrid system. In the boat I was designing I had a reverse mounted engine with the gear box fwd and vee transition box breaking the drive train in two parts. This meant that an electric motor could be easily mounted on the vee drive gearbox face driving the output shaft directly. This arrangement also pushed the engine aft under the cockpit floor for easier access, while also keeping the drive shaft lower and more parallel in the shallow draft hull. To go hydrid with my current Southerly it will have to oarlocks on the cockpit coatings.

Great Video. Plenty of comments about the hybrid system! From a technical point of view I would say the serial hybrid is the way to go. (Its been used since the 1960's on diesel electric trains). But for a new design serial has so many technical advantages. But what about practical and cost implications? Perhaps there is a reason its not so popular? Or is it its just harder to retrofit a serial system than a parallel system?

The one thing people don’t address here and HH glosses over is the cost vs the actual benefit you get. I was quoted $100k from HH to add the parallel hybrid system. So put this into perspective, a performance cruising catamaran uses about $2,000 of diesel annually. Even if somehow you eliminated the entire need for diesel it would take 50 years for this system to pay for itself. BTW, the 4kW of solar are the flexible type that are less efficient and only last 5-7 years vs 25 years for glass panels. I love the concept, but the math and economics of it just isn’t there. We went with standard diesels 3.6kW of fixed glass solar and dual Integrel chargers.

@@marccohen5477 Mike is referring to moving under power for days on end, something which Uma doesn't do. At the moment the only way to do that on a monohull is with diesel, until methanol is widely available that is. Yes it's possible to cruise under sail and electric power alone, but you have to adapt if the energy you use daily is at a certain level. Notice for instance the amount of time Uma spends in marinas hooked up to shore power. In their arctic cruise they were reliant on a small Honda generator. So if you adapt, you can do it, but you need to adapt your itinerary as well.

Seams the boat industry is a little conservative yet regarding serial hybrid systems, but i am quite certain that's were sailboats are going to end in a while. A serial hybrid has several advantages in that the components are smaller and easyer to install, you have more options on where to install items like the generator, you can use a smaller generator, electrcal generating mode when sailing, smaller footprint of the motor means you can install it under the floor and so forth. The downside is that you probably nead a higher voltage motor to get sufficient power for a 49 feet boat, there are more components in the system that can fail, danger of electrical corrotion, aging in time for power electronics that probably will mean replacement of a costly system earlyer than a typical diesel engine. At this point in time life expectansy of power electronics is aproximatly 15 years. For a modern diesel engine with common rail it's probably 2-3 times that. Regarding electric coocking: This draws mutch less power than i expected. Electrical appliances is very easy and comfortable in practical use. You will never go back to gas after switching to electrical cooking. Heating water and cabin is a wery different story. You will not be able to heat a boat at high latitudes by solar panels. Best of luck with your new build!

Imagine there's transfer case that'll allow the diesel to use the motor as a big giant generator as well. Parallel hybrid makes the most sense if you want the best of both worlds and safety on long passages. I'm very interested... Sirius, are you paying attention ;)

This is the system that HH catamarans use. The hybrid engines can be run in "charge mode". In this setting, the clutch to the shaft is disengaged and as the engine runs, it just turns the beltdrive without any effect on the shaft/propellers. The beltdrive runs the alternator/generator and produces around 9KW of power that is used to recharge the batteries. So in a boat with a hybrid setup, it now becomes optional to have a separate generator

Europe's inland waterways and lakes are converting to electric boats very rapidly, that's why most of the bigger names are based in Europe, like Vetus, Bellarine, Oceanvolt, Torqeedo etc. The industry is moving quite rapidly, its just not well accepted for sea going use, as many of the large Yacht builders cannot get buyers to take on a new technology, it really needs to get them into the charter / rental markets, to demonstrate its effective uses, and weaknesses, bit like the car rental business.

i like it...great idea. not sure about the cooking though. I like having both systems. its a good back up maybe?

Regeneration will be interesting to see how well it works for your boat. No doubt it will work better on his HH catamaran, as the cat will sail faster, as well as have two props in the water. As for Starlink goes, it is a great device. I have used it myself. Unfortunately, I believe folks using the RV version on their BOATS are in violation of the terms of service and I fear eventually they will be cut off… Hope not.

You may also want to consider Sharrow props. Increased forward thrust, and significantly reduced vibration and cavitation. They custom design the props to work best with your hull shape.

Hi, thanks for another great video - very informative. I only discovered your channel recently and have really enjoyed it, thank you. However, if I haven't missed something I'm surprised you haven't yet converted to an all electric galley. For cooking especially with induction hob and microwave/ convection oven combo its more efficient than gas and a whole lot safer and you don't have all the issues with sourcing gas at different ports around the world which can be very problematic. Cooking on a good induction hob gives as much control as gas but way safer and more energy efficient. Eliminating gas also makes your boat way safer and does away with all the complex plumbing and fittings (and cost) that need constant maintenance with no more frustrating excursions to find gas in remote ports. For water heating it does not make any sense to use solar electric. Given that the best solar panels on land with an ideal orientation to the sun are only about 20-23% efficient if you are lucky. This is a huge waste of solar energy and requires a large footprint. On land at least one can use direct solar water heating and I'm surprised that this option is not considered for boats as its very efficient and the footprint of the panel is very small compared to a solar electric panel. Also the solar can be further concentrated using fresnel lenses. For those times solar water heating is not possible then a dedicated deisel fired water heater is more efficient than running an engine for heating only. As you already have a diesel engine you also have the fuel available. For propulsion my personal preference would be serial hybrid as it simplifies the drive system. I have also been following the adventures of "Sailing Uma" and I very much like their setup. Technically they have what you might call a serial hybrid setup except they use a small portable generator to top up batteries rather than a "primary diesel" and rely only on direct electric drive. They've done many miles and I don't see them reverting to the older ways. There are a few other cruisers who have discovered the solar electric alternative. (naturally one has to adjust to a different approach to sailing without having a huge engine backup for extended time available). I am trained as an electrical engineer in a former life and am very interested in exploring alternative energy for boats. I am currently planning a boat build and will be going with an all electric system with small backup portable diesel generator and direct solar water heating. For cabin heating and alternative water heating will go with a Charcoal Burner and make my own charcoal (I may use diesel as backup to this). You'd be surprised how easy it is and the raw materials can be found anywhere in abundance (eg. driftwood, unused wood scrap, dead trees, shrubs etc. can be found on just about any shoreline. This waste wood is only going to break down anyway if not used so does not add to CO2 in atmosphere. Anyway, as invited, these are my thoughts (although still developing). Cheers dj

When I calculate battery capacity I always have in my mind to use battery between 35 and 70% most of the time. It is about the cycle life of cells.

The StarLink demonstration is amazing! And having two parallel hybrid diesels in a catamaran is engineered redundancy that is often missing in many designs. Good to have an owner who is an electrical engineer for whom redundancy considerations are fundamental. With that said, the most important aspect of these types of systems is re-generation, a.k.a., hydro-generation. To optimize the hydro-generation, it may be necessary to have a variable pitch prop, since a propeller optimized for propulsion will not be optimized for hydro-generation and vice versa. I am aware of only one vendor who is producing a system that supports a variable pitch prop: Oceanvolt. Have you considered this option?

There is another type of serial type drive, the elec driver is on the shaft of diesel engine, between prop and diesel trans. It will cause a little bit more when diesel running, and it can charge the battery use the same motor. Once charged in full, it can switch back to elec only.

I enjoyed this episode. A hybrid system seems pretty good, although I really like what Dan and Kika have done with Uma. As far as I go, my sailboat is only 20 feet. If the wind dies, while lake sailing, I have a 4hp Eninrude outboard for auxiliary power. I also carry a spare paddle/oar just in case. : - ) A large percent of the time I sail out and back into the boat launch on wind power only. I haven't bought gas for my outboard in at least 3 years, so I've got a very small carbon footprint while boating - unless you include driving to and back from the boat launch. BTW - Is there a way to see some of your earliest episodes? The 20 years ago kind?

This guy isn't too stupid. He seems quite rational. A- There are four propulsion options: 1- The first one is to just have one primary electric drive, convert all forms of energy into electrical energy and then run that drive with electrical energy generated from an internal combustion engine, a nuclear reactor, a steam turbine, or a battery bank recharged by solar, wind, wave or hydrogen sources. 2- The 2nd option is to have a primary shaft driven by an internal combustion engine and a smaller backup electrical motor for emergency. 3- The third option is to convert all forms of energy into steam and then use that to drive the shaft. 4- The fourth option is to extract hydrogen from sea water and then use that to drive an electric motor. I would prefer a mast with either an IC engine or an electrical motor for secondary power. B- Storage: Electrical power can be stored in batteries, steam or hydrogen. 1- Since renewable sources don't generate much electrical power, I would rule out steam. 2- This leaves batteries or hydrogen as the most likely electrical storage media. Hydrogen is more easily replenishable, but volatile, so those who want to risk the volatility can choose hydrogen. I personally would choose a sail plan with an electrical motor driven by a generator and renewable sources with storage in batteries. I would still want to have diesel on board to drive the generator in emergencies

Why not get a silent yacht? Thoughts on those?

Very exciting to be at the forefront of what is currently possible. If this was my installation, I'd want to downsize the diesel engine/fuel tank as much as possible and increase the battery/solar accordingly. Are there electronic controls available to get electric assistance to the prop when it's being powered by diesel, for example for occasional added performance (so full power is e.g 60/40 diesel/elec split), or must they be run independently? Also, are you making any sacrifices to levels of electrical equipment so that your battery/solar combo has the best chance of covering your domestic needs? Interested to know what your philosophy is for 'going green'. The boat's looking terrific, by the way!

Looks like an amazing vessel. While I do appreciate what you are doing and have done, my real KZread sailing hero’s is UMA. Take a 5000 dollar near 50 yr old mediocre bay and costal cruiser and sail the Caribbean, and then cross the N Atlantic with just a small electric motor. Sail the UK, Scandinavia, Norway, winter over in Norway sail to Svalbard! Then sail over a thousand miles SOUTH to Iceland! And then back to Europe. And all the while doing incredible documentation and video. All on a shoe string. Very very impressive. Granted if I had a choice I would rather make the trips on YOUR boat. Ha ha. Now……………if I just had a few million.

There are two main advantage of series hybrid over parallel, the first is that you can usually simplify the electrical motor and propellor connections. The second is that if you design your Diesel engine and generator to operate at a single fixed speed, you can tune them (especially the diesel engine) to significantly improve overall efficiency. The electric, series hybrid black cabs that operate in London were designed that way but I haven't seen reports confirming that they are actually more efficient than their parallel cousins.

Hybrids can be quite efficient but I think it's difficult to have a more efficient installation than a traditional diesel engine which is operating at its design cruising speed usually around 3/4 load. The main area when a serial hybrid will win is if it operates slower say at 25-30 percent. So if you have a 15kW generator operating efficiently and driving your boat electrically it will be more efficient than a 80hp diesel running at just 20hp (equivalent to 15kW). We did look into the option of a serial hybrid viewing an installation of StokElectric.com. They used a 80kW electric motor and a 30kWh generator. So you would only have a brief period when you could use the motor near full speed, but still a pretty powerful generator to top up with. One issue of the 80kW electric motor is that you can't stay with a 48V battery bank and system. They are using 350V power and that was something I was a bit worried about having aboard such a high voltage.

And I agree that Operating at high voltage in marine environments is very scary, and I think I read somewhere that you required special training and certification to work on marine equipment that operates above 48 volts.

Check out SOK Battery's. They are CSA,UL listed IP67 waterproof and they are very reasonable in price [ $1680 us for 48 volt 100 amp/hr 5.4Kw }. If you have the electric motor mounted to the crank shaft of the transmisson , when or if you use the diesel you will charge the battery's at whatever the electric motor is rated for say 10 KW or maybe a 20KW , which will recharge your battery bank from 5%-80% in one to two hours. When sailing there also will be the 10-20 KW recharge, enough for water heating in most cases as once the battery bank is full you can have the excess power routed to the hot water tank via relay .

Chat to Uma about regen and props. Hybrid seems the current way to go. Electric for 90% of the time, regen when sailing and then diesel in a pinch. Ref hot water - talk to Hone. They do combined solar and electric panels. No idea if it would work on a boat. One of the mega yachts uses a heat pump for hot water I believe.

I was supprised the question of having a generator + electric motor didnt come up more. For myself I found it more efficient to have the serial hybrid, so then you down need to have diesel motor + generator. Generator are way less complex than a traditionnal motor connected to a shaft, and can be usefull for many usage,, like hybrid water heating as well And the most important for me i think is the possibility to have hydrogenerator integrated in the electric motor system.

It could be interesting to get your thoughts on the pros and cons of the safety aspects of diesle vs electric. Looking at the power plant as safety equipment, how much energy (diesel fuel or watt hours) should be kept in reserve for unexpected problems/emergencies such as weather, rigging failure, unwanted guests, acute health issues etc. What position do you put yourself in, if offshore, you do not have sufficient energy reserves to deal with the unexpected probpems/emergencies that seem to pop up. Does one form of energy have advantages of disadvantages over the other.

@d.j.vanderschoot3717

Жыл бұрын

On a monohull you must calculate that almost all energy will be derived from diesel, especially in northern climates. Regeneration through the prop and electric motor/generator will help cover for a modest house load if you are sailing fast enough and all the time, but not for AC. Then again AC is required in southern climates only where solar generation is easier to maintain, but from a 1 kW solar layout you will also need to generate some energy from diesel as well. The battery bank is there as a buffer, using the diesel more efficiently and at higher revolutions. Diesels don't work at all well for manoeuvring, going on off anchor, loitering to wait for bridge openings etc. That is where the electric propulsion comes in.

Would love some comments from you as to why you chose not to go with the Integral system this time around.

There would be two electric clutches forward and aft of the induction motor. Several operating modes are possible. You can use the induction motor to start the diesel.

First of all I apologise for this rather late (and negative) comment but I am a bit of a Luddite on this one. It is one thing going all electric and getting rid of gas and there are clear advantages to doing so. The investment in a relatively large Lifepo battery bank can work well with solar to support the domestic load. But when it comes to serious propulsion (in contrast to enter and leaving harbour) the hydrodynamics and power requirements work (cube law) against it and this is what prevents dispensing with the diesel altogether (a sensible decision - if you do not want to be a casualty). The cost premium is one aspect of any form of hybrid system that causes me to shudder and the attendant increase in Lithium battery capacity required (likely four times as much). You have also introduced a whole different level of complexity AND you still have the diesel engine and the fuel tanks. Of course with enough money you can pretty much do anything. But in my opinion, the only benefit of electric drive is to reduce emissions and you are going to pay for that benefit (and not get very much drive). On the positive side I absolutely love everything you do and am ploughing through the backlog of DS4 videos to catch up - it’s a wonderful project and wish you every success with the project.😀👍⛵️

Have you evaluated the difference between using a diesel engine and using a diesel generator to give you the backup you need? How does a diesel generator compare with a diesel engine in terms of efficiency, capital cost, weight, complexity, and reliability? Do you have an energy/power budget? Ignoring propulsion, what do you estimate the total energy requirements per day of a cruising couple, say for basics (navigation, cooking, hot water etc.)? How much will you use for heating in the high latitudes or air-con in the tropics? These are really interesting details. Thank you for sharing your experiences.

Hi MOC, thanks for your comments :-) Yes we've been trying to evaluate relative efficiencies. It seems that in various situations and circumstances there are different winners... We do have an energy/power budget which has increased substantially over our 33 years of cruising. However we have always used gas for cooking. Because of that we are quite comfortable with the safety aspects of gas but do not know how much electric power to budget to replace the gas. BTW we are keen to get rid of gas mainly due to the fuss of finding refills as we travel between incompatible gas fittings worldwide. Heating is another question... we have installed forced air heaters in our 2 most recent boats but have no obvious way to avoid another diesel heater on the new boat. There is WAY too much energy used to heat a boat to ever dream of replacing it with solar. The new boat will be our first try with Hydronic heating which also makes a much smaller tidier installation. For AirCon we will be be doing AirCon for the first time and do not imagine it will be too difficult to run minimal A/C for a couple of kWh. After all we have go on without it for years and consider it a luxury. The more I write here the more I realize we need to to a video on Energy/power budgeting for the new build! Thanks!!!

I think hybrid is best suited for a catamaran, given the ability to carry so much solar. There is a constant demand for electricity on board. Being able to use electric to get away, or into, a Marina or anchorage would be nice, but it is done at the expense of “stealing” battery capacity from the house needs. Even if price were no object, a monohull has more space constraints for battery storage. (if you keep them low in the boat) With lithium’s increased charge times, adding a high output generator to facilitate charging while motoring into and out of marinas etc is probably a better way to go. Maybe one day a boat designer will design a boat the way Tesla designs their cars, incorporating the batteries as part of the structure, integral to the car/boat itself. A little outside the box thinking could go a long way - could not some part of the keel be used for storage? Just thinking out loud, best of luck with the boat!

Hybrid is a genius Idea but I wonder about the practicality when sailing mainly in Northern waters. Is there, or will there be enough strength in the sun, and enough of it, to have the panels generate sufficient to keep the batteries with enough charge all the time…..? It’s fine I guess if you are sailing between the two Tropics, so I wonder what data you have accessed in order to get a view on this? There’s nothing worse than not having enough power to boil the kettle….!!!!!

On our Boréal 47.2 Fabule (Canadian registered) I cook a meal for 4 with 10% of our 10 kWh Li-ion bank, so about 1kWh. For more elaborate cooking I would count 1.5-2 kWh per meal. On passage the most demanding equipment is the auto pilot, with the fridge and the freezers. Drains about 4-5 kWh per day including pilot, electronics and life support ( freezers, fridge, microwave oven and water boiling, and water maker). No AC though which drains a lot of power. Generation: 2x 350W wind generators, 900 W solar arrays, 600 W Watt&Sea hydro generator. Diesel 4kW generator for hopeless days without wind or sun (and to drive the dive compressor). Hot water for shower is on hydronic diesel Webasto or with diesel generator. I would increase solar if I could (lack of place on monohull unfortunately) but the rest is sufficient even on cloudy passage so that the genset is almost not used, but this includes often bit of motoring which tops up batteries, say 10% of passage time in average. Hope to cross path on the sea sometime. Salutations de Lagos. Fabule

If you have a Python or Aquadrive aft of the engine (for vibration reduction and alignment tolerance) then you can take that out and replace the belt that way.

Looks like an elegant solution but you are always turning the crankshaft when using the electric motor, which is detrimental to efficiency, especially if you use the electric motors a lot. Yet they don't seem to market that any more and I couldn't find many practical examples.

Wenn Hybrid then serial, so you can earn energie while sailing. The belt Solution seems little dangerous if it breaks when manouvering

Using a diesel engine to turn an electric generator (or alternator) to charge a battery that then powers an electric motor cannot be as efficient as having the engine just turn the propeller shaft.

Large alternators and solar array, with lithium batteries and dc air-conditioning allow most boats to go without ac generator today as well as conventional shore power, requiring only the battery chargers to plug in anywhere in the world any voltage any hertz. What is really missing and offer a great advantage for cruisers under sail with reduced maintenance, is an all-composite retractable drive system, much like Mcconaghy has been installing in racing boats for a few years. No corrosion, no barnacle fouling, no drag under sail, why hasn't some done this yet on a production cruiser?
