Congrats!!!!!! I am at port of Everette converting my 30 Catalina as we speak. Would love to come see your set up and vice versus if your interested. I'm a mechanical engineer by trade, pulled my diesel out on Friday, cleaning and prepping my engine bay, and installing a 48v system as well. Should be motoring by Tuesday, just waiting for thrust flange bearings to arrive tomorrow to finish fabbing my mount! Congrats again!

Hi all,
Just wanted to thank everyone for the valuable information I gleaned from the group to successfully convert to electric. I would like to share what I've done so others can benefit. I started on it in November 2018, worked long hours every weekend and sailed her home from Seattle to Anacortes at the beginning of May 2019. So far I'm very happy with the results. I will post some pics and vids later (spending a lot of time enjoying the results right now). I will also collect and post performance stats to help anyone considering a similar conversion. Here are the basic build details for anybody interested:
Boat: 1972 Buchan 37 sloop (built on Lake Washington in Seattle).
Beam: 10 ft.
Waterline: 27 ft.
Displacement: 13k lbs.
Shaft drive (offset).
Previous ICE: Volvo Penta MD2B 2 cyl diesel 25HP
Electric replacement:
Thunderstruck motors 10 kW Brushless Sailboat Kit
48 CALB 100ah cells arranged in a 3P16S battery, for a total of 15.36 kWh storage, (12.29 kWh useable). For those who prefer amp hours, it's a 300 ah / 48 V battery.
Performance (more to come later):
Top speed between about 5 kts.
Range at 3 kts seems to be way more than I need so still need to push it to see how far. Most of the time I'm running her about 3.5 to 4 kts with no sails and using around 40 amps.
