A sea of booze, bikinis and blow-up floaties.

From an emergency management standpoint, the 2017 event was too much. 

"What happened last year, can't happen this Fourth of July. Our resources were completely maxed out by one group in one particular area," Shayne Enright, Honolulu Emergency Services said. 

The annual ocean party in Waikiki turned into chaos:  hundreds of rescues and about a dozen people who wound up in the hospital. All in one concentrated area.

"The number of rescue assets available on this island were essentially all deployed to this event at great taxpayer expense and to the detriment to all the other people on the island who may need these rescue assets," Petty officer Eddy Crochetiere, U.S. Coast Guard said. 

The Coast Guard, DLNR and Ocean Safety lifeguards will be back at it again this year. Their message: leave the alcohol off the beach and out of the water. 

"One of these years, one of these days, something terrible could happen. So we're there to ensure safety of life at sea," Crochetiere said. 

They'll also be going boat-to boat, checking for people boating under the influence, drinking underage and operating illegal or overloaded charters. 

"Anyone who happens to be operating a boat overloaded with too many passengers, there voyage will be terminated and sent back to shore immediately.... The fines that go along with boating under the influence on the federal side go up to $5,000 in fines. The boat may be confiscated and then of course there are state and local laws that also apply," Crochetiere said. 

It all comes back to manpower and concerns emergency crews will be stretched too thin.

"With the thousands of people who attended Flotilla, the rescue resources will be overwhelmed like last year and it may not be possible to cater to the thousands of people that attend," Crochetiere said. 

"We have an entire island of nearly one million people that we need to be available for... it's not about managing it. It's not about having the resources," Enright said.
