State crews were out in waters at Ala Moana Regional Park on Friday installing new buoys that separate swimmers from stand up paddleboarders.
The original buoys were installed four years ago and some had become saturated with water and failed. Another one is missing.
The new ones are mooring buoys designed to be more resistant to water infiltration and built to last.
"They're actually a little bigger, a little bit more sturdy. People won't be able to hang onto it. We had some issues with some people hanging onto the buoys," said Meghan Statts with the Department of Land and Natural Resources Boating and Ocean Recreation Division.
DLNR first installed the buoys to separate swimmers and paddlers as stand up paddleboarding gained in popularity.
The department says altercations between the two groups dropped sharply after the buoys were installed.
