How many chase boats are needed and how many cats are expected?
I see that there will be boats that finish fast and boats that lag behind. You will need several chase/rescue boats. There has to ba a boat taking uo the rear to insure (ensure)complete safety. I think at least 3 power boats, 1 to watch the front, 1 to watch the middle and 1 to watch the last boat, all with cameras to document the action.
