Royal Caribbean's Explorer of the Seas was docked next to Star, and passengers aboard both ships reported minor contact between the two.
Cruise Critic learned of the incident from Chris't'ian Swan, who was in Bermuda at the time and e-mailed about the event.
Winds reached speeds of 45 knots, and flooding occurred throughout the area.
"At approximately 1:30 p.m. EDT today, a high wind squall caused Norwegian Star's aft mooring lines to break while the ship was docked in Bermuda. There were no injuries, and after a short time of being at anchor, the ship re-docked alongside at the pier," a Norwegian Cruise Line spokesperson said, according to the Bermuda Sun.
Star was on a seven-day cruise to Bermuda, and it is expected to depart as scheduled, the spokesperson said.
