US owner Lindblad Expeditions has cancelled the first voyage of its new cruiseship National Geographic Quest.
It said the vessel, being built at US yard Nichols Bros, has a technical problem that needs more time to address, according to Travel Weekly.
"During our launch, the shipyard team encountered circumstances in which the vessel began moving out of alignment, forcing the operation to halt," Lindblad said.
"The ship remains poised to launch, but the nature of tide cycles, and the need to realign her entry in the water, caused delays that will affect the yard's ability to deliver the vessel to us in a timely manner."
Quest was due to head to British Columbia and Alaska from Seattle on 26 June.
The next trip on 8 July is expected to go ahead.
