The commercial tour catamaran involved in an accident that killed a 13-year-old boy Friday had been cited for numerous safety violations in its most recent inspection but corrected them immediately and had a valid certificate to operate at the time of the accident, according to Coast Guard records.

Coast Guard and state officials yesterday were continuing to investigate the safety records and condition of Na Hoku II, whose metal mast snapped off Waikiki on Friday, pinning the boy and injuring two women.

The Honolulu Medical Examiner's office yesterday identified the dead boy as Jordan Loser, 13, of Riverside, Calif., who was visiting the state with his parents as part of a tour group.

Na Hoku II was towed to a fuel pier at Ala Wai Harbor, where investigators were checking for structural, engineering and navigational problems, as well as looking at past safety inspection records, said Coast Guard spokesman Michael De Nyse.

The Coast Guard's Maritime Information Exchange database shows that Na Hoku II was last inspected May 23 and 24. Officials cited a long list of minor problems, but none appeared related to the mast that failed on Friday.

Among the problems noted in the inspection report were poor sail winch mounting bolts, improper maintenance of the navigation, stability and lighting systems, improperly installed lifebuoys, and operating without a valid certificate of inspection.

Most of the violations were immediately corrected at the time of the inspection, and on May 24, the Coast Guard issued the 14-ton Na Hoku II a new certificate of inspection that will not expire until 2011.

Peter Young, chairman of the state Department of Land and Natural Resources, said state and Coast Guard officials were cooperating in the investigation. He said the state also would start its own investigation.

Since Na Hoku II is a passenger vessel under Coast Guard jurisdiction, the state had not conducted its own inspection of the ship before Friday's accident, he said. Young said Friday's accident was the first one in his memory in which someone had been killed by a broken mast in Hawai'i waters.

"We will also follow up from our side to look at how we can continue to keep recreational boating safe," he said.

The accident occurred about 4:20 Friday afternoon while Na Hoku II was about three-quarters of a mile off the Elks Club, according to the Honolulu Fire Department. Northeast winds were in the 17- to 21-mph range.

Federal records also show that there were only seven boating fatalities in Hawai'i in the past five years. Five of those deaths came in 2005, according to U.S. Department of Transportation databases.
