I have installed an electric inboard in my Catalina 30 sailboat. The next step for me is to take it on its proto-shakedown voyage.
As promised, a link to the spreadsheet with motor use data:

Amazing job, learning to be able to do this to my own so great videos!!

@openrov272 2 года назад

Thanks!

Great to see the review of the data.

@buzbybaker 2 года назад

Great series on your conversion, It would be good if you could give a lot more tech info on make of thrust bearing, motor, batteries, suppliers etc etc for those of us about to do the same. I am in Europe and need to transfer your specs to something I can buy here. A discussion about why you made your decisions about which bits of kit to use would also be useful. Great stuff, very encouraging.

@openrov272 2 года назад

I'm working on a 'howto' type video which covers this sort of thing. :D I hadn't thought to mention the thrust bearing. I will add that to the list of points. So thanks for mentioning it.

@buzbybaker 2 года назад

@@openrov272 Thanks for your reply. It would appear from the other comments you have really perked up a lot of interest. Thunderstruck seem to have a really good reputation, unfortunately getting their stuff sent to Europe costs almost as much as buying the motors, Because of this I am looking at Golden motors from China with all the risks involved in that. I am in the act of ripping out 2 perfectly good diesels from my 40ft catamaran to be replaced by 2 10kw motors.

@islandman9619 2 года назад

Thanks for making these videos! I'm thinking about converting my boat to electric the next couple of years, but it's probably quite a bit heavier than yours which is a concern I have. Looking forward to more information on how you like this.

@openrov272 2 года назад

I will keep up dating the spreadsheet as I gather trip data. :D It seems that though there is plenty of power available for maneuvering etc, hull speed is, I think impractical, as a cruising speed. Increasing speed by 1 knot doubles the power use. For every knot! Ouch! So traveling at 4 knots uses almost twice the power of 3, and 5 uses almost twice the power of 4 etc.

@islandman9619 2 года назад

@@openrov272 Yes, that seems to be the case for everyone I've seen with electric. You need to have flexibility with time. I'm curious how much solar you'd need to run the boat at say 1.5 knots indefinitely (given sunny skies). It is unfortunate that the range is so limited, but I can probably live with that as long as I get rid of the noise, smell, and all that dirty diesel and oil that seem to end up everywhere. I guess it's possible to have a diesel generator for desperate situations, but I'm not sure if that'd even be a win...Anyway, will be interesting to follow :)

@kentfletcher8539 2 года назад

@@islandman9619 The short answer to the question "how much solar" is basically: More than you can fit on the boat.

@openrov272 2 года назад

Actually, 1.5 knots, for my boat, would be feasible. At least according to the spreadsheet from Thunderstruck: docs.google.com/spreadsheets/d/11nS-zKICpU4-aEOmdiiC_DXrGL1TdEAj/edit?usp=sharing&ouid=117405574190775181504&rtpof=true&sd=true You should be able to download a copy of this google sheet. Then you can change the numbers. I found the numbers to be somewhat pessimistic compared to what I'm getting on my boat. It assumes calm conditions. At 1.5 knots it would draw 170 W. and 2 knots it would draw 400 w. at 2.5 knots it would draw 780 w. But most people won't be happy with 1.5 knots, or even 2 knots. :D So @Kent Fletcher is mostly correct.

@islandman9619 2 года назад

@@openrov272 Most people don't have time and I understand that, but for me that's not an issue. Now, if you can add 1.5 knots and motor sail in light winds, you might not be much worse off than with a diesel on long passages where the sun shines or wind blows. You also don't have to secure any fuel to the deck, which is a major plus (on long passages). Cheers!

Looks good do you have a layout as far as what you are going to be doing for solar and your total battery? Thank you

@openrov272 2 года назад

I do intend to add solar, but I don't have a plan for that yet. :D

@marlonalves1491 2 года назад

Good Job! I'm studying to install this system on My Cal25, what do you think about I use a 5KW motor?

@openrov272 2 года назад

According to sailboatdata.com/sailboat/cal-25 you looking at 4000 lbs (plus your self and your stuff) and according to Thunderstruck: www.thunderstruck-ev.com/sevcon-brushless-sailboat-kit-5kw.html the 5 KW is good for up to 6000 lbs. So the 5 KW looks like a perfect fit.! :D

@RulgertGhostalker Год назад

like the charge voltage is the charge voltage....so the MPPT programming would ask for a nominal voltage and cell type.....and the MPPT then is entirely based on the current output.....and at some RPM, the current would be limited, where the product would remain the same, no matter how fast the prop was spinning.

@danielpowers5946 2 года назад

Hey man I also got a Thunderstruck motor and I am going to be using it on my Hunter 27'. I really appreciated your videos for information and ideas and to see someone else doing this! I was wondering- are your batteries for your motor separate from your house battery bank? Or do you use a step-down converter to go from 48 to 12? How do you handle that situation?

@openrov272 2 года назад

I'm keeping my house bank for now, since I already have it. When it come time to replace those batteries I am leaning towards getting more 48v and using the step-down converter. :D

@danielpowers5946 2 года назад

@@openrov272 So (Im assuming your house bank is 12v), do you have the two systems connected at all? or do you have separate chargers for both systems? If you have separate chargers for each bank, do you split the shore power coming in between the motor batteries' charger and the panel (then to the charger) for your house bank? (and are your batteries the same chemistry?)

@danielpowers5946 2 года назад

I know these are long questions- Im just trying to learn as much as I can before I get started on my install

@openrov272 2 года назад

The house bank is lead acid, 12v. I have separate chargers. I have the house-bank charger connected to the panel, and the motor-bank charger will also be run through the panel, and shore power is to the panel. Currently the motor-bank charger is plugged into a regular ac "wall" socket inside the boat. It is 110v. I will wire that up soon. :) The motor-bank charger draws about 8 amps at 110v (I think. I have not measured, but that's what the math says.) Feel free to ask questions. If I know the answer I will do my best to help. I'm working on a "Howto" video, and I will add your question about the chargers to the list. :D

I'm working on a "HowTo" video right now, but it's not ready yet. Here is where I got my kit: www.thunderstruck-ev.com/electric-sailboat-kits-and-accessories-inboard-motor-ev/ AND here is where I got my batteries: signaturesolar.com/eg4-wp-lithium-battery-48v-100ah I'm happy with both so far. :D

@@openrov272 yeah .. that would be awesome (and get tonnes of views) ... if you could catagorize the expense as well .. looking like upwards of 5,000.00 for the refit to my 31 CAL that cost me 3,000.00 there in lies the rub... thanks again for the reply !!!

@clivestainlesssteelwomble7665 2 года назад

Other option is to find a damaged nissan leaf, use the motor and its controller gear.. Theres one on I tube in a vintage Criss craft motor boat.

@RulgertGhostalker Год назад

prop re-gen is like mapping a maximum load curve....but talk to your controller manufacturers about marine specific software updates, and learn it......i don't know if they have a marine specific software update for it, but the software should function like MPPT in re-gen.....( with an adjustable current limit that lets the prop spin more beyond a point ) so if they do have a marine MPPT re-gen software update, it would be a piece of cake, otherwise you have to work for it, like you're hacking the system to get what you need.. the Sevcon controller re-gen is like a rubber tire on a road.....well it's not quite like that, is it?

A motor , battties and heavy cable wiring …. In a salt water environment 🧐 Interesting

@michaelmccotter4293 2 года назад

I endured your motor install videos and still have not heard a single mention of what company makes the motor or all the components? Is it a kit? Did you source parts separately? Throttle device? Batteries? System HP, KW rating? Cost of conversion? Beside your spreadsheet not much useful info after watching too many chaotic videos. Sorry.

@openrov272 2 года назад

This is valid criticism. Now that the install is complete, I'm going to do a more organized video explaining things. I used the Thunderstuck Motors sailboat Kit. www.thunderstruck-ev.com/electric-sailboat-kits-and-accessories-inboard-motor-ev/ The 10 KW motor. I bought the Wig Wag throttle, because then I could put it anywhere the wires would go. I bought 2 X 51.2v 100 AH (5.12 KW) batteries from signature solar. So total of 200 AH @ 51.2 v (10.24 KW) signaturesolar.com/eg4-wp-lithium-battery-48v-100ah I chose these, in large part, because they were available and the others were not.
