Converting a boat to electricity
Discussion
(you know what I mean!)
27' GRP cabin cruiser, currently powered by 40hp inboard diesel. It's noisy and vulnerable to weed clogging.
Top speed required is 7mph (normal cruising speed 4-6mph), and enough power for a weekend trip - say 12 hours' cruising between charges.
Possible? And if so how much and where to get the bits?
(If the motor needs to be water-cooled that would spoil the plans a bit though)

Couple on YouTube from USA using a Tesla motor and battery bank conversion on there yacht.
Learning the lines is there channel name I think. Although they are just starting the conversion but it does look like it’s going down the route of a bodge it job though but I will have to wait and see.
In theory it seems like a good idea if you can charge the batteries from solar, wind generator and towed generator and keep it all dry and functioning in a marine environment.

This is what you need.

In a home conversion I would say keep the system voltage low 48V or so.
You will need to work out how much power kw you need to push your boat at it's cruising speed and calculate kwh capacity of batteries reqd.
Get a rugged industrial air cooled motor and controller package.
Use old EV batteries leaf etc... To cruise for 12hrs is quite a big ask , so say your boat uses 6kw then you will need an 80kwh pack..
48v pv and wind generator stuff is all over e-bay so fit as small pv/wind system to keep it all charged up when not in use.
Presumably it will be days between jaunts..

Thanks folks - I should point out that the boat is inland, and the marina has shore power, so recharging isn't an issue.
The Elysian 27 is very close so that would be worth pursuing. Also the Vetus link; my boat has quite a few Vetus bits.
Apparently 40hp is 30Kw... so if my sums are right that Vetus 2.2kW motor is only 3hp - that can't be right surely? Another website says 'The Oceanvolt AXC series is a modular system available in four power configurations 10kW, 20kW, 30kW or 40kW; the latter of these provides power to the equivalent of up to 100hp'. In which case I'd need 16kW...
PS That NauticExpo link looks very interesting; it's clear I need someone with experience to help me pick my way through the jungle. Unfortunately I don't think there are any!

Sailing uma also using one on theirs. Learning the lines is there channel name I think. Although they are just starting the conversion but it does look like it’s going down the route of a bodge it job though but I will have to wait and see.

No association with the company other than they have a picture of my boat!

I found that but they seem to be hybrid systems, ie they retain the original engine.Simpo Two said:

Many of these websites seem to be a page of guff, a CGI image of a boat - and no actual real life examples at all!
