Kokua Line: Is SUP ‘rule’ at Ala Moana in writing?

Question: Is there anything in writing about where the stand-up paddlers should paddle at Ala Moana Beach in the ocean (the side with the buoys, not Magic island)? I’ve heard of an unofficial “rule” that the stand-up paddlers should paddle on the outside of the buoy. However, especially on Saturdays, the stand-up paddlers are on the inside of the buoys where the swimmers are swimming laps, and it can get gnarly sometimes.
