The old WillyT and the Kodiak Queen are white balls available for anyone. They do change colors as they tend to use whatever is available for replacement. In Jan they were all white balls. It’s not all that hectic. The key to the balls is just be courteous. If we are diving and come out of the water if a boat waiting we drop our gear on the deck and get off the ball. Then we sort out the gear. The commercial boats tend to do most of their diving from 9 to noon. Occasionally might see a boat out at 1. Same applies to snorkeling. We don’t sit on a ball for hours having lunch and sunbathing if others are waiting. You will find much of the time however no one is waiting. The Baths and Indians after about 8 am to noon or so being the exception.
If we don’t win the boatyball lottery at Cooper we will often just get there around lunch and grab a FCFS ball. There are multiple dive sites that can be reached by dinghy from Cooper. If it’s a nice day going to the Rhône is not even a problem by dinghy.
