The colors came about from the colors of the water (blue) and the race flags or buoys(orange/red). They do vibrate a little together. I see your point. Also, more colors means more screens, and likely more money. It depends on the process used.
I also think that around the circle we could write "Catamaran Association of Biscayne Bay" and even maybe geographical coordinates.
Sure, we could combine ideas. This would make it relate more to the stickers and banners. It would make sense.
So... lets wait for more opinions on the design to move forward.
PS. John better have some extra stickers left over! I just sent in my membership dues!
