INTRODUCTION
Any time you picture a body of water larger than a puddle, one of the first things that comes to mind are the rolling waves, or the surf lapping at the shore. Well, at least that's what happens with me... But waves are much more than tranquil anomalies, they can be dangerous and destructive to any vessel in almost any body of water. Understanding how waves are made, how they normally behave, and how to predict their response to weather can make the difference between a smooth, comforting time on the water and a bumpy, frightening experience.
The first rule of waves, especially in the open ocean, is that there are no rules. Kind of a hypocritical statement considering the intent behind this article, but it is a hard, cold fact. There are simple physical factors that makeup the "normal" wave, but within the forces of nature, there a myriad of other factors that need be considered into the equation. Regardless, an understanding of what makes a "textbook" wave can be of considerable merit to the sailor. What we will examine here are the laboratory examples of wave creation. How, in a perfect world, waves would behave. In reality, alternating weather patterns, varying water depths, opposing currents, fetch obstruction and a multitude of other factors may change the way waves in a particular area react.
