Define "fetch" in sailing terms.

The term "fetch" in sailing refers to the distance over which the wind can blow across the surface of the water without encountering any obstacles. This unobstructed stretch of water allows the wind to build waves, which can significantly affect sailing conditions. A longer fetch means that the wind has had more opportunity to exert its force on the water, resulting in larger waves. Understanding fetch is essential for sailors as it can impact boat handling, speed, and safety in various weather conditions. For instance, a fetch that is shorter would likely lead to choppier, less organized wave patterns, while a longer fetch can create more powerful and more consistent waves, which can be either advantageous or challenging depending on the scenario.
