- The Fantasia Sailing conversion to solar electric systems. In episode 1 Fantasia the 15.6m catamaran is introduced, the 10kw Golden Motor unboxed and the system overview explained. Then a test run run of the motor is shown before the de-ICEing of our 30hp diesel is completed. The conversion of the Volvo saildrive will be detailed in further episodes, along with the LIFEPO4 batteries, 48v Solar arrangement etc,
You and Carolyn are amazing Andy. Looking forward to more episodes.
Chat soon.
Thanks Mark! Great to hear from you!
Very clean setup and love the innovative idea.
I was looking at purchasing a very similar motor - a 25kw ‘Paraglider’ electric motor to put into an electric motorcycle build so it’s awesome to see you using this 10kw as an engine for the fantasia 👍
Those Paraglider 25kw motor look very interesting. The open style housing would obviously aid air flow and cooling, but you would need to filter the air. Cooling is a key thing which I will be looking at in detail in my coming videos.
Very impressive to lift the motor up and out, so many boats end up with a hole in the deck
Oh yes, cutting a hole in the cockpit to crane it out would have been easier but more work in the long run!
I installed the same motors on my Cat but I kept the bellhousings and made an adapter plate to mount the motors. I also put both hand throttles into the same housing and got rid of the old cables. If you had taken off the flywheel it would have lightened the engine a lot.
I also had to change the reverse power in the program because was not as fast as I liked. I am now working on getting the motor info on my chartplotter.
Oh yes, I never thought it was possible to get that flywheel off the D1-30. That would have made it a lot lighter!
Thank you for sharing and a MASSIVE congratulations on designing and building your beautiful boat, I don’t think a lot of people know how much time effort and passion go into designing and building a boat, not to mention a high performance catamaran. Well done and look forward to more of your awesome and humble videos.
This is the kind of material that should be all over tv, Netflix eg
Thanks again mate
Thank you Mick! Yes, when you have a passion the work is easy. I did take 9 years designing my boat and 4 years 3 months building it, but in many ways 14 years after its launch it is still a work in progress! If you want to know more of the Fantasia story, all the passion, adventure and romance is set down in "Windward to Fantasia" my carefully crafted book on Amazon. Thank you so much for the Kudos. Regards Andrew
Great work mate. Im looking forward to see the performance comparison with the diesel. Deny
Sorry to not reply earlier Deny, but for sure your super cat will be perfect for some kind of electric drive. Being a solar installer no doubt you will be able to arrange a good system. Cant wait to see the big Key's design up and flying!
Not sure how happy Carolyn would have been getting engine grime on the linen during the removal process.☹. Although I am sure she will be happy about the much cleaner result.. What are the advantages of the 48v system? Such an interesting project, watched the vid 3 times now! Looking forward to the performance test results in terms of distance and run time capacity etc. Well done for now.
Haha, so much grime came out of the engine room! In this first part of the conversion you really notice how much cleaner life will be! 48v seems to be the max voltage for DIY projects. Compared to 12v the wires need only be 1/4 the size. Higher voltages do gain more efficiency though but moving to 48v was enough of a leap for me!
Hello Andrew, great work. I am in Perth, Western Australia. I'd like to do an electric drive for my 38' steel mono. A parts list and supply companies would be awesome.
Hello Steven, thank you. Yes, such a list is certainly on the way.
Glad to see you doing this conversion .. optimising the prop size and pitch is important with e motors as they produce more torque lower down ..
Ive tried persuading Mark from Wilding sailing to power his Wharram.Pahi with a couple of these in the 15kw form . Instead of 9hp two stroke outboards.
I thought Golden motors only introduced the Axial flux motors recently ... and these were the radial motors. I will go back and read it again.
Looking good mindyou ..theres a guy in the UK with a Heavenly twins cat with twin these motors... and it performs exceedingly well.
Hello Clive. The prop aspect is interesting, but not something I have a huge grasp on! I have been running tests and noted yesterday that the 10kw actually develops thrust faster than the 30hp diesel, which relates to this low down torque. I'd say these motors would be great on 9hp outboards.

I ve just seen this I will see if I can supply you with some comparative information tomorrow..
The extra torque of electric motors puts them ahead of most ICE motors. So they can swing larger props with more blades usually. .. they are also more controllable as you don't have to rev to generate a given thrust.
@@clivestainlesssteelwomble7665 thank you that would be very appreciated. Just getting a handle on the differences between electric and ice seems tricky. So I can see they have more torque early, while the ice needs more revs to generate torque. Any info would be great.
Will be interesting to see the performance.
I'm doing a similar thing 14m powercat, ex sail boat, initially was going to go with a 48v possibly 96v setup but have now gone with nissan leaf motors - 150hp outboard conversion and will most likely use Tesla lfp batteries.
Yes, 96v gives better efficiencies. I wish you good luck with this project. Plan things well and press on.
The other super safe option and easier to maintain is the Blade lfp batteries that were originally developed by BYD..
@@clivestainlesssteelwomble7665 I'll check them out, cheers

They come in various lengths now .. from the original long Rhino ones are half or a vehicle width to a very short briefcase length version or what looks from the outside as a prismatic.. it helps with voltage and space fit. On a boat you should have less restrictions on space.
The other person who was headed down your route was a German guy converting a cat lifeboat. .. Heart of Gold 🥇 but he hasn't posted for some time.
Theres a uk guy whose built a converted Al fishing cat hull with Leaf motors.. its featured in PBM.
I was fearful that the motor was going to spin off the bench.
Haha, yes have seen many people with theirs carefully bolted down for testing! This 10kw motor was remarkable stable and smooth running like this unsupported.
I have the same battery bank and plan to use the same motor... I'm really keen to see how this works for you!
I think you will be pleasantly impressed. I have all the content and will be releasing new videos soon with all the interesting details.
Oh yes, it'd be it'd be cool it you could subscribe, which would help us. All the best.
What was your reason for choosing a box-type enclosure for the motor? Is it intended to provide some type of protection against water flooding the motor, in the event of a leak?
Yes, the box enclosure is quite important . For one it distributes any loading on the saildrive over a large area, so in case of grounding the box takes the pushing load into the forward engine mounts. It means the set-up is just as strong as when a diesel was mounted there. Also as you point out it it protects the works in case of engine-room flooding. I have sealed it and the top of the box is well above the waterline and the engine bay is also sealed from the rest of the boat. Yes, I have seen Oceanvolt owners building guards in front of their saildrives which are only supported by a small radius.
I have the same motors and controler in my cat
Great! They seem a pretty good build. How are you finding it? Do you have water cooling?
@@AndrewStransky-cc2dr yea water cooled, they are powerful enough but atm I'm using potentiometers to control them and I can't figure out how to make a dead spot in the middle so it easier to find the off position. Looking at a way to use hall effect instead and make something with levers and detents. The bought ones are either very cheaply made or extremely expensive
@@Sailingon interesting to be using potentiometers. I used the foot type throttle attached to my morse controls that the diesel used, to keep it simple. I was surprised how little travel it had when I tested the motor, but now that it is under load it is fine and the position of the lever is fairly similar to the diesel side. Yes, they are a very simple thing these throttles as I had mine apart hoping to adjust it, which lead to to trouble which I had to set it back to how it was. They just look like some kind of magnet passing over a sensor. I am quite happy with my throttle now, having made some adjustments via the EZekontrol app and a slight tweaking of the throttle insides.
Are you going to have any sort of fire suppression system on the motor or battery? Wouldn't want any sort of overheating problem or short to cause any damage.
Hey Maximitz! I will certainly be dealing with this important aspect of electric motor installs in my coming videos. Thank you for reminding me.
hello , great work ! can you tell me the prop details please? pitch and diameter
Yes, I have 16.5 inch diameter and 13 inch pitch. 2 blade folding Gori prop. We did originally have a 17 x13 and this may well have offered a bit more thrust.
Question : Catamaran and only one motor?
Sorry if I wasn't clear enough but no, we have a motor in each hull. We have just converted one of them so the other 30hp diesel is still there... So we basically have a hybrid system now.
where did you get the motor?
I purchased it direct from the manufacturer, Golden Motor. They have a comprehensive website and are very helpful. Delivery was very quick.
