Yep. A good rule to remember whether it's electric propulsion on land and water or drugs: "SPEED KILLS"

Yet another example of the generalization below hull speed: Power doubles for each knot.

Sure, mph doesn't equal knots, but you get the point.

Thanks.

Power really goes up with speed. The Lyman 13 is about 400 pounds, plus 130# batteries, plus 40# motor, plus 185# captain, plus 55# dog. Water was calm.

2 mph 50 watts
3 mph 150 watts
4 mph 300 watts
5 mph 600 watts
6 mph 1200 watts

I figure the two Optima batteries have 1800 watt hours capacity.
