After the American Cruise Lines vessel grounded Thursday, tugs were called in to assist.
A spokesperson said work is progressing well but the effort is taking longer than expected.
'We are working with the Coast Guard to disembark guests this morning via tender and have them proceed to Nashville, where they will be able to participate in regularly scheduled shore excursions. There remains no damage to the vessel, no pollution and no other resulting areas of concern,' the spokesperson said.
She added: 'American Cruise Lines has been operating in Lake Barkley for almost 10 years and while we regret this incident, we look forward to continuing to visit and explore the wonderful ports and communities along the Cumberland River with our small riverboats.'
American Jazz accommodates fewer than 190 passengers. The spokesperson declined to say how many people are aboard but local news outlets are reporting 120 passengers and 54 crew.
The ship is on an eight-day 'Music Cities' cruise from Memphis to Nashville.
