White fish are further sub-divided into: 1  Round White Fish. Examples include cod, haddock, hake and pollock. 2  Flat White Fish. Examples include plaice, lemon sole, brill, turbot, black sole are common examples of this category. 3  Cartilaginous Fish. Ray, rock salmon and shark are examples.
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).
Now if you add a 10hp motor, you can plane the boat. The speed might go up to 15-25mph. This is because the boat is no longer using all of the hp to make a big wave.... As stated above, some motors may be rated at 1/2 - 3hp, but the usable power in these motors is more like 1/2 to 1hp. Without gear reduction, most electric tolling motors really do not produce much additional thrust above about 1hp.
