Indigenous-owned Alaskan Dream Cruises ended operations on Feb. 4, a decision owner Jamey Cagle called "intentional and necessary."
The company is processing refunds for guests with reservations.
"We have had the privilege of sharing the wonders of Alaska and the richness of our Alaska Native heritage with incredible passengers from across the globe," said Cagle. "It has been an honor to work alongside extraordinary communities, partners and crew throughout this journey."
Alaskan Dream Cruises operated four small ships for 40 to 80 passengers. It was established in 2011 by a Tlingit family and described its cruises as having a "casual expedition atmosphere" that offered a local's perspective.
Its founders also own a boat-building company and a day-cruise tour company, Allen Marine Tours.
"After careful evaluation of our long-term objectives, we determined that concluding cruise operations allows us to responsibly focus our resources where they will have the greatest impact," Cagle said.
Cruises were inclusive of meals, shore excursions and airport transfers. The cruise line did not offer WiFi, saying the sailings were "a time to unplug and enjoy nature."
