Wave height question?

[bowguy84]

I guess I just don't understand how this works. Why does the buoy only measure up?

I don't know the answer to that . Thays just what I've been told by a lot of captains around my marina maybe tincan can tell u why

Actually I just read post 12 on the new weather buoy it takes a average of the trough to the top of the biggest 1/3 of the waves so people usually double that because there are likley waves that big out there becaused of the average thing.
