In just three years, a solar sail could reach a speed of over 160,000 kilometers per hour (100,000 miles per hour). At that speed you could reach Pluto in less than five years. photon reflecting off the mirror-like surface of a solar sail gives the sail a double kick -- a push equal to twice the photon's momentum (one push from the sail stopping the photon and one from it reflecting the photon and accelerating it away).
All paddle boats are designed to have a maximum speed. This maximum speed is usually only a couple miles per hour, which makes the paddle boat safe for the whole family. When you reach the maximum speed, it no longer matters how fast you pump the pedals. You will not make the paddle boat go faster.
