MIAMI — Carnival Corporation’s new cruise line Fathom has been forced to cancel its first cruise due to delays incurred when the U.S. Coast Guard’s inspection of fathom’s ship, Adonia, took longer than expected.

Fathom’s first passengers were supposed to set sail Monday from Miami, for a seven night cruise to the D.R. According to CruiseCritic.com, more than two dozen fire screen doors on the ship were inoperable. The ship had been in dry-dock and immediately began operational tests under the direction of the U.S. Coast Guard. The tests took longer than expected, according to a statement from Fathom, leading the cruise line to cancel its soft-launch inaugural sailing.

Fathom is offering passengers refunds for both the cost of the cruise and airfare, as well as out-of-pocket expenses.
