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).
Speed of an average sailboat Does anyone know just how fast the average sailboat is(when I say average I mean a monohull cruiser). I would LOVE to believe that it is about twenty mph. If anyone here knows how fast the average thirty footer(my preferential lenght) might be, I would love to know.
