Phase one of the project was the proof of concept. It showed I could build an e-kayak for under $1,000 that could travel at a walking pace with a range of at least 2 hours. 

I ended up with a range of ~16 miles (4 hours) and a max speed of ~4.5 mph. I was super happy with the results and learned a lot through my first round of testing! Next step is to get my computer out of my lap and build up the oar hardware cluster!
