Points of Sail . . . Is this Right ?

Most Points of sail diagrams I have see are like circles and have the wind coming from one direction while the boat moves around it. Thats backwards to me because I want to have the boat pointed in one direction and have the wind move around in relation to the boat. I also want to add the windex on the mast into the equation in relationship to the beam. I wanted to see if there was any correlation between the angle of the windex and the angle of the beam, a quick way to determine the reach. I am very good at close hauled, seems to be the easiest, its when I am reaching that I am in a not sure zone. So I made this diagram to show the relationship between the wind and the windex and the beam and jib...is this correct?

Slightly off topic, but what book is that if you don't mind me asking.

The reason i ask is the pages you have put up are very familiar, but i can't place the book....

It's mine, not even a book yet just papers, that I started years ago but never finished, so it was not in circulation. I typed it out on and IBM Selectric w/hand drawn pictures, in the 80's.

BTW Cuajota, the Windex will be different/variable to the wind direction because of the forward motion of the boat, which is called 'Apparent Wind'.
