In the Fall of the year there's a 24 mile electric boat marathon held on the Wye river on the eastern shore of MD. All kinds of boats and electrical systems show up. Of late, lithium batteries have been used, although the second place overall went to AGM batteries. Motors of 8kW and over are classified in the extreme category.
I'd like to compete in the under 8kW category. Efficiency is king, and there are many areas to consider efficiency: hull design, prop design, prop drive, and motor and controller. My question to you all: what specification of motor yields the highest energy output per kW input?
Weight is an important criteria also. Lighter is better.
And finally, what are the sources for lightweight highly efficient motors; who makes them? Thanks in advance for your input.
