Treading water gently here(not trying to be a jerk):
If it was in fact you(group of 6 or so) it looked like you were having a good time, but you were oblivious to an approaching boat(mine) as your group snorkled and dove for a toy between and in front of anchored boats.
We patiently waited for your group to move on so we could safely pass by you and tie up with our friends not sure which way you would turn next.
My wife thought I was getting too close but I thought by being a little closer someone might notice us(or our motor noise) and move on.
