Fathom, the new impact travel unit in Carnival Corporation & plc group, had to cancel its first cruise that was due to sail on Sunday from Florida to the Caribbean due to issues that arose during safety inspection by the US coast guard, Cruise Critic reports.

The new venture is using the 710 passenger Adonia, which was transferred from sister company P&O Cruises in the UK. The 30,277 gross ton ship continues to be managed by the Southampton based company and it flies the British flag. It was built in France in 2001.

"The vessel had run into some issues; the main issues were that the fire screen doors, approximately 30 of them on one of the decks, were inoperable. We're working with the cruise ship to make sure that this is taken care of before they can get underway,” a Coast Guard spokesperson was quoted by Cruise Critic as saying.

"The ship arrived in Miami directly from dry dock and re-fit offshore and underwent rigorous operational tests with the U.S. Coast Guard that took longer than expected. Unfortunately, the company has learned additional testing will be required and as a result must cancel the soft-launch sailing," according to a statement from Fathom.
