In the interest of others who may be confused with wind direction in relation to waves or angles you are expected to use in certain winds, here's something I made yesterday. Hopefully it makes sense and is correct...I'm sure if it's wrong I will be told. Feel free and I'll amend.

I've opted from using sailing terminology as much as possible as, like myself, many don't use most of it. But if you want to know Google "Points of Sail".

NOTE: I'm not a wavesailing expert but was knowledgeable in the field in a previous life.

EDIT: (1) In Key changedd what the red X means also added to Key "All angles in between". It doesn't mean 'go in that direction'. (2) New pic title.
