Subject: Re: [Electric Boats] Greetings! New conversion
Hello Steve,
We are in a very similar situation. Our boat is a Moody 425 (Monohull, 10to, 12,70 meter) which we want to convert.
Contacted Oceanvolt and got an indicative offer which nearly put us off the project.
After watching Kika & Dan from Sailing Uma we have decided to go ahead and our plans so far look like:
a 12kw 48 Volt DC Motor along the lines of the

48 Volt LiFePo4 Battery, build from single cells
https://evea-kartmasters.fr/en/lithium-cells/2130-gbs-32v-160ah-lifemnpo4-lithium-cell.html
a solar array of 800 - 1000 WP (maybe more)
a 4kva AC Genset (which was already installed by the PO)
The first step is to learn and decide what speed you want to be able to
do using your motor. If you reduce to 95% hull speed your motor needs
drop to 70%.

And after that you need to figure out your range requirement, or if you
want to use a genset as range extender the size of the genset.
Further thoughts go to replacing the gas cooker with an induction stove
as the engine battery serves as a really big house bank when at
anchor....... and the tender already has a epropulsion outboard. No more
gas and no more outboard fuel reduce our ressources needed to diesel for
the genset if at all. With more solar and our windgen we may already not
need the genset. We will keep the diesel tank for heating purposes........
And most important for us: improve our sailing skills. The more you sail
the less you need a motor......
