I have been unable to find definitions for the many different chart layers. For example, what is the difference between Waves, Swell, Swell 2, Swell 3, Wind Waves. Same questions for Wind, Wind Gusts (self explanatory), but what is Wind Accumulation.
It would be great if there was a page to provide an explanation of all layers and when/how best to use them.
Other than that ... this is an awesome website.
