Electric Conversion log for Kahleesea
Thus begins my hopefully not-too-eventful conversion of my 1994 Hunter 29.5 to electric.
~10kW motor @48V
~2 hours cruise speed @ ~5kts
Biggest, slowest 2-blade prop with the biggest pitch I can find - target RPM ~600 at cruise for maximum efficiency
Hull speed under motor power alone for short sprints (current Yanmar cannot accomplish this feat, tops out at about 6.5kts WOT. hull speed is 7.2)
Regeneration while under sail
Project completion ~ April 2019.
I'm open to suggestions as to motors, batteries, etc. I'm leaning towards a motenergy 1114 with a 5:1 gear reducer and used Volt batteries, since they're 9.5x9.5x10.5 and it will be easier to fit them in my available space than other lithium batteries.
Step 1 is this weekend - take video of the Yanmar 2gm20 starting up and running to show it's in good working order, and then post it for sale. Hopefully it will sell quickly. I'd like to remove it from the boat and drop it into the buyer's truck, as I don't really have space to store it anywhere.
