City Island residents are growing increasingly frustrated with Jet Skiers and boaters they say are putting swimmers at risk and keeping residents up all night.

The City Island Civic Association has written a letter to police, including Commissioner Dermot Shea, about what they see as "rowdy and reckless behavior" on the water after dusk.

They are urging officials to construct a permanent harbor patrol base, saying that the Bronx is the only borough without one.

Residents tell News 12 that on average, they've witnessed harbor patrol boats leave City Island every night at around by 8 p.m. They say by 8:05 p.m., the waterways become a "free for all."

"It's totally out of control," says Maria Sutherland of the City Island Civic Association. "This is our fourth year working with harbor patrol and the NYPD on this and we have been with our local legislation and really been trying to get someone to hear us."

On Monday, there was a fatal Jet Ski accident that took place near City Island. Members of the civic association say they fear more accidents will take place if officials don't take immediate action.
