Firefighters rescued 13 people Friday night after the sailboat they were on ran aground outside Ala Wai Boat Harbor.

Honolulu Fire Department Capt. James Todd said the keel of the 46-foot sailboat Boomerang got lodged on the reef near the surf spot Ala Moana Bowls about 7 p.m. The crew, which was participating in a boat race, lost the ability to steer and oncoming waves from a south shore swell continued to push the boat towards shore.

Firefighters used surfboards to bring all 13 — nine men and four women — back to shore where some were treated by paramedics for hypothermia, Todd said. All were released at the scene.

Todd said firefighters asked Hilton Hawaiian Village to hold off on its fireworks show until the rescue could be completed. The fireworks were delayed about 20 minutes.
