Norwegian Cruise Line President David Herrera has left the company, with the head of its parent company taking over for now.

Harry Sommer, the current president and CEO of Miami-based Norwegian Cruise Line Holdings, which oversees NCL as well as Oceania and Regent Seven Seas, will assume day-to-day responsibilities for the company’s marquee cruise line effective immediately, according to a statement from the company.

“Aligned with our continued strategic evolution and focus on our charting the course strategy and 2026 targets, NCL is entering a transformative chapter in its nearly 60-year history that will elevate the guest experience even further,” Sommer said in an emailed statement. “Marked by seven next-generation ships on order, major enhancements underway at Great Stirrup Cay, the greatest private island in the Caribbean, and an expanded Caribbean presence, the brand is well-positioned for meaningful growth.”

Sommer had previously served as NCL president after taking over for Andy Stuart in late 2019. He then took over the parent company when Frank J. Del Rio retired in 2023.

“I am excited to work closer with the team at NCL to capitalize on the many opportunities ahead as we embark on our search for the next leader who will guide the brand into the future,” Sommer said. “David Herrera has been a dedicated member of our leadership team, and we are grateful for his decade of contributions to NCL’s growth and success. We wish him the very best in his next chapter.”

The change is effective as of Wednesday, and the company is working with an executive search firm for a new cruise line president.

The line did not reveal the reason for Herrera’s departure.

Herrera oversaw the launch of NCL’s last two ships, Norwegian Viva and Norwegian Aqua, as well as recent announcements for the expansion coming to the line’s private Bahamas island Great Stirrup Cay.

He was previously the brand’s chief sales and marketing officer and held other roles since joining the company in 2012.

As a U.S. veteran who served in the National Guard in Florida, Texas and New York, he helped develop NCL’s military appreciation program.
