yes
If there is no wind and the sailboat has no auxiliary engine
It would be, yes, because we need wind for many things, but there is no ethical problem, as it is physically impossible to do this. It can be unethical to use anything faster than it can be replaced, depending on what it is. To do this with trees is unethical, but with coal it is not.
Light
No. Nothing is faster than the speed of light. Even the fastest wind doesn't come close.
By controlling its flow across the sails: If the boat is light enough, it WILL move faster across the water than the wind does.
by wind force
No, ocean waves cannot move faster than the wind that generates them. Waves are a result of the energy transferred from the wind to the water's surface, so they generally travel at a speed proportional to the wind speed.
A westerly wind means that the atmosphere is moving faster than the Earth spins.
Neither is faster than the other. A twister and a tornado are the same thing.
Sound does not travel faster than light. The speed of light is 299,792,458 meters per second The speed of sound is 343.14 meters per second or, light travels at 186,000 miles per second sound at 751 MPH
In general, a rowboat is not faster than a sailboat. Sailboats utilize the power of the wind to propel them forward, which can be more efficient than rowing. However, the speed of a boat can also depend on various factors such as design, size, and conditions.
Although the first steamships were not faster than sailing ships, steampower meant that ships were not dependent on the wind for propulsion anymore, so this meant that ships could go, independent from wind and wind direction. Thus improving the reliability of transport over water.
