Juneau police have arrested a longtime whale-watching boat captain for operating under the influence with more than a dozen passengers aboard his tour boat, after he was detained by the U.S. Coast Guard Wednesday.

In a statement on the case, Juneau Police Department Sgt. Chris Gifford says officers received a report from the Coast Guard at about noon Wednesday that 67-year-old Lawrence O. Dupler had been detained as an “intoxicated boater,” for operating a 52-foot tour boat out of Juneau’s Auke Bay with passengers and crew aboard. Officers met Coast Guard crews when they docked.

“(Dupler) failed field sobriety tests offered by Juneau police,” Gifford wrote. “He was arrested, and later provided a breath sample revealing an alcohol concentration of .115.”

Reached by phone Wednesday afternoon, Gifford provided a head count of the people aboard at the time of the incident.

“There were 13 passengers aboard, and two crew members in addition to the captain,” Gifford said.

Gifford declined to identify the tour boat’s operator, citing a decision not to do so by JPD Chief Bryce Johnson.

A spokesperson for the Coast Guard, Petty Officer 3rd Class Diana Honings, confirms that 13 passengers were aboard at the time of the Coast Guard boarding. She didn’t have word about what maneuvers the boat was making at the time, but was able to identify Dupler’s company.

“The Coast Guard received a tip from a crewman aboard the vessel,” Honings said. “He was working for Orca Enterprises.”

Orca Enterprises’ website says Dupler has more than 35 years of experience as captain and chief engineer on vessels ranging from fishing boats and tugboats to diving boats and pleasure craft. The company, owned by Carol Pitts, offers three whale-watching tours daily to the coastline of Admiralty Island; ticket prices run from $59 to $119 for children or adults.

“Captain Larry, an internationally renowned whale watching captain, accompanied by a professional tour guide/naturalist, bring years of knowledge and experience to your personalized excursion,” a description on the website reads. “Come with us for the whale watching and wildlife adventure of a lifetime.”

A woman who answered the phone at Orca Enterprises Wednesday afternoon said nobody was available to comment on the case.

Dupler is being held on $1,500 bail at the Lemon Creek Correctional Center, with any Coast Guard disciplinary measures against him or the company pending further examination.

“Right now it's still under investigation, and any punishment will come after a hearing,” Honings said.
