Composite Keel How To - Eureka

[LarryA]

I have, on numerous occassions over the past couple years, gone to the composite keel section and never understood what it was attempting to depict. I finally get it. It is so simple I can´t believe I did not get it immediately. If you have changed the page, congrats, it clearer. If not, well, glad I finally got it. (I was starting to think it was like statistical mechanics - took it twice in undergrad and once in grad school and never really got it).
