Hi Kris and Don,
Hope this is a little clearer than mud. The point is the Wave likes a windward, then long reach out, long reach back and a windward/leeward,
While the Rave likes a windward, then a really long reach (unless it is light air -- they need somewhere over 10 to begin to fly at decent speeds), then back to either a Leeward mark and then to finish, or just to a finish. They are not at all interested in the weather work or leeward work -- a pure reaching machine.
I don't know or remember what we had last year, but two windward marks would be fine, and two reaching marks -- one for a beam reach or a little lower that is about twice the distance as the upwind leg, (FOR THE WAVES), and another a mile or two past the Wave Reaching Mark (FOR THE RAVES).
If you don't want to use a C (Leeward) Mark, I think that would work for most of the classes.
Below is some of the artwork we use for the Tradewinds Midwinter Open Cat National Championships, which is usually over a hundred boats of all makes and kinds of cats, tris and foilers. What a mess!:
