How do i know.
In my spare time I’ve been designing in 3D CAD a modular hull of prefab sections and each section to hold large battery packs(decided to stay in 50volt zone), each 70kwh. The smallest boat @ 44’LOA is multi-utility platform on the water and can fit three BESS modules all connected to a central BMU. So, these fully charge power packs can feed both the ac load panel… as well as the propulsion system when desired. Each 4’ hull module assembly added to the boat length will allow another 70kwh of stored energy. So, although the PV is small, storage is high. The banks can be charged twice as fast using shore connection but that’s cheating. The project’s goal is zero emission on the waterways.
The ePropulsion looks cool but from what I can tell from their site, the outboard and battery is sold together.What for brand .
My self looking for a hybrid systeem.
So i have look in to this systeem
So i can use the diesel engine to make power and charge the battery with it
But the systeem is on 48 volt .
This is the model my self looking for.

Not for the Navy and bigger series. They come with just a battery cable you can connect to pretty much any 48V battery. I have a Navy 6 and have it connected to 48V of Li-time
Love the thought of an electric boat, but also love the thought of 20-foot-long-class boats that plane, so let me know when 100HP-ish electric jet modules are available...
They already are available. How thick is your wallet is more the question.
Not that thick.
It’s something new my organization is working on, a low displacement zero emissions cabin cruiser with ample space for battery packs. Given the corrosive sea environment and the limited options for power conversion equipment made for it, I decided to stay at 50v zone for battery packs. I can push the envelope only so far and sometimes innovators have to be patient for the gear to become available and reliable. I know about the Elco 48v options and two might be enough, but only testing on the water will tell us.
Awesome! Do you share some details somewhere?
So you’re a sailor, doing a retrofit. Great! I have too long of a history working on boats to imagine any possibility of customizing pre-existing. I’m starting totally from scratch, even patenting a composite hull material to circumvent the need for one-off molds and brittle, glass/resin or below waterline cavities, thru hulls… that tend to let water in either slowing or catastrophically. Also has to be ADA compliant. Might sound ambitious but to me it’s just another puzzle to solve.
A big enough flat bottom or catamaran might be your answer. They don’t rock like traditional hulls.Electric car parts.com has both a 96v mppt and a battery charger listed on their website.
For the bms - consider Batrium- it can handle a high number of cells in series.
I have thought about doing exactly what you are doing - I only have two issues 1. $$$ 2. Boats rock and my stomach doesn’t- I would likely be sea sick a lot.
Hull type does make a big difference as to rocking. I’ve found that the thing that helps with nausea better dramamine or prescription meds is ginger root. Gnaw on some slices or buy candy like Gin Gins. Comes in lots of flavors. It doesn’t leave your mind in a fog like meds do and I think it works better. The money part I can’t help you with since all boats are a hole in the water which you pour money intoElectric car parts.com has both a 96v mppt and a battery charger listed on their website.

Absolutely does the bottom of a mono hull make a difference on stability. My boat was 43’ long and was much more stable than some others that were bigger and heavier like trawlers. There were numerous times when it was tied up on the same dock with yachts, all receiving the same broadside waves. When you looked down the row of boats it was easy to see how much more stable it was. Would I take it out in heavy seas with that hull design? Hell no! That hull was more for inland waters. It had a sharp bow that reasonably quickly transitioned into a very shallow V or almost a flat bottom. My personal belief is the most efficient hull type for electric propulsion is a displacement hull catamaran ( think two canoes spaced apart). My boat was planning hull and I usually had it just on stable plane for best efficiency but that’s not what a eco electric boat needs.

So true… which is why I’m designing a big hull that makes only a shallow hole. The yachting market is a big racket ripping of guys for a hundred years.Hull type does make a big difference as to rocking.

You have the right idea, Sky. Also, by placing the majority of ballast (tanks, battery) inside the chine area the roll motion is less due to inertia. But in this 43’ motor yacht’s case most of the mass is right near centerline in the form of 2ton diesels…. so ignore what I just said about ballast and chew some ginger root.
