There's always a few knuckleheads who have to go and ruin the fun for everyone else.

Here is a simple recommendation, allow the fun to continue but ban the use of floaties. Floaties are hugely detrimental to our environment and make party goers feel more secure than they are. It is not the canoe paddlers, SUP surfers, boat captains, or sailors which are the issue. It is the inexperienced and disrespectful "floaters" who are a menace and simple don't belong. 

I make my recommendation as someone who has participated in the "floatilla" many years but has always been appalled by the general idiocy and lack of respect for our oceans. 

Personally, I would support a perma-ban of floaties in Hawaii waters or at least Waikiki. They tend to encourages folks to get in "over their heads" in rapidly changing ocean conditions and create tons of trash.
