Electric Propulsion NC 1095

[captainwanabe]

Has anyone used electric motors on their NC 1095?  Evoy has a large enough electric outboard motor. Has anyone tried their motors on a NC1095?  I am thinking of going all electric but I have not heard of anyone else going that route yet.  I would love to hear of any developments or tests that have been done with electric propulsion, batteries, solar panels, and the like on a Jeanneau power cruiser.

Thanks,
Capt. Wanabe

Evoy’s website indicates earliest availability of 2023 for their 300HP outboards (for which they aren’t yet publishing actual performance specs). 

What electric propulsion options are you considering?

The problem with electric boats is that modern lithium based batteries don't have sufficient energy density to provide the necessary energy for the use cases most boaters demand.

A high-end Tesla has a 100kWh battery.  The 1095 has two 106 gallon gas tanks.  A gallon of gas contains 33kWh of energy.  So a 1095 carries about 7000kWh of energy with full tanks.  In other words the gas tanks on a 1095 hold the equivalent of 70 fully charged top-end Tesla batteries.

Of course, electric motors are roughly three times more efficient at converting energy to work compared to gas.  So really it would only take about 23 Tesla batteries to provide equivalent range to the gas tanks in a typical 1095.

All this is a long way of saying the problem with electric boats is not the motors -- it's the batteries.

If you want to learn more about what electric motors are available I'd suggest this web site.

If you want to learn more about lithium batteries for boats I'd recommend the Facebook group "lithium batteries on a boat".
