Do you think it's a crime to change engines for something different?

Dear all

I read you for a long time now, even before forum changed or crashed if I remember well, in 2010/2011, after I bought Jaquenetta, a Freeman 30 from 1964.
First, I'm french, so apologies in case of miss understanding.

Before make Jaquenetta presentation, i'll allow myself to ask you all if you think it's a crime to change original engines by something really different and "new"

To clarify a bit, perhaps some of the oldest members remember my first presentation? But for different reason after some wonderful sailing, I had to let her for quite a longtime and now for 2 years search for a solution to do not let her die in an harbor.
The engines has taken water and seemed out of order. Deck and roof was plenty of holes and leakages and really wet, dashboard was also very critical.
Also, hull was full of osmosis.
But she's so beautiful that it was for me impossible to not to do something

Some pictures, as we had it after interior cleaning

Hi
I am assuming the first four pictures are when you owned her for the first time ? Absolutely beautiful !

The next three are now ? Such a shame she has got into this state.

If l understand, you are now the owner for the second time, and feel you have to bring her back to the original condition.

If this is the case, l applaud you, it will be a massive task but l understand your sentiment entirely. Extremely well done !!
And keep posting progress .

Hope you get her back looking great again. I voted no, it's not a crime to me to bring mechanicals up to date as long as the visual parts of the boat look as original as possible. I would love a modern diesel in mine but ar £8-9k i cannot justify it. 
Best of luck ☺

No, all pictures are "initial" statement. Just we discovered that deck was rotten. 
We review it like : (deck, roof and hull, this last has been treated with epoxide)

I replaced old engines by 2 electric pod 10kW, with twice 10kWh battery.
This system allows 50/60km autonomy at 6 to 8 km/h (perfect for the Britany rivers).
No sound, odors, neither mechanical spares needed on boat.
It's absolutely wonderful.
I didn't try yet on sea, but will once i'm sure of reliability

Wow 20kw to drive a 30 foot hull. I wouldn’t have thought that was enough? That’s like 26hp whereas originally with 2 diesels it would have been 3x that

It’s very interesting. Help me out here. If you have 20kwh worth of battery for 20kw of motor and you cruise for say 50km at 5km/hr that implies 10 hours of cruising, which means you are running at a 1/10 of full power which seems very low.
If you were at sea I guess you would need at least  20kw and then your time is limited to one hour?
One thing is for sure..it’s the future! No reason it shouldn’t be reliable and love the quiet! I guess the only downside is the cost of batteries and the degradation. How do you test reliably for that and what is predicted battery life? It must be a massive cost to replace them all?

First, do not compare theorical power electric/thermic. The equivalent of these electrical 2x10kW is 2x25CV (same « driven », is it the good word?)

And sorry, battery name contain 5000, but real is 5275Wh, 5% more (around Wink )
They’re German and use BMW i3 cells. They’re done for more than 3000 cycles, 

The tests and travels I already made show that I need between 900 and 1500 W to drive 6 to 8 km/h. 
I also did in one step 40km, average speed 7km/h and keep 30% power at the end of the day

The maximum speed is close to 12/14 km/h, and effectively only one hour ! So it’s a non sens. 

The cost is a beautiful car...
