  Curve is the word

The graph is not a line, it's nowhere near being linear in nature

Power vs speed kayak graph rockets skyward almost exponentially
due to the frictional forces on hull shapes

The paddling horsepower needed almost doubles going from
5.5 mph to 7 mph due to frictional drag.
Athletes need an ouput of 0.1 0.2 horsepower
to achieve 5 - 7 miles per hour
World class marathon kayak racers can achieve 8 mph and more
at near 0.3hp output.
