HONOLULU -- Plans to keep swimmers and standup paddle boarders separate -- and therefore safe -- at Ala Moana Beach are making waves.

Ala Moana has long been designated a swimmer's beach, but the resurgence of standup paddle boarding has sparked controversy over the safe use of the beach.

The protected waters make Ala Moana an ideal location for both swimmers and paddlers alike -- but the two groups are quite literally on a collision course.

Vernon Knight was hit in the head two months ago while swimming.

"It caused a lot of blood and caused me lots of concern," said Knight.

Knight was one of about 100 people who turned up at an informal meeting to discuss the best way to keep out of one another's path.

The state has been reluctant to hand down rules that might either ban paddleboards or be difficult to enforce.

"For us, it comes down to, 'How do we get these two groups to come together and come up with some sort of resolution?" said Shane Kapea, a standup paddler.

Paddleboard enthusiasts said the sport has taken off because it provides a way for both old and young people to get active.

"It's good exercise," said Meaghan Stotts, with the DLNR Safe Boating Division. "You got your health and it's bringing families together."

Both groups realize that things can't continue as is, but they also realize that they will need to compromise as well.

The state plans to try to set out buoys along the shoreline so paddlers stay toward the reef while swimmers stay toward the shore, and hopes to enact the plan for six to eight months. However, the state still has to work out some issues with the city about posting signs, and must also evaluate what role lifeguards may play in educating beach users.

"The paddlers who have been out here for awhile -- even the swimmers -- we all need to educate these people," said Reid Inouye, with Paddle Core Fitness. "Learn how to do it first and be safe about it -- and stay away from the crowds."

Inouye has a state permit to operate a paddleboard business at the beach. Other operators who used the beach called upon one another to take responsibility for the people they introduce to the sport.

Some swimmers still prefer splitting the beach park, allowing one side for swimmers and another for paddlers. Yet, both groups agreed that option could pose a problem with access and parking.
