The wave hit Crystal Cruises' 1,070-passenger ship Crystal Serenity while it was en route from Spain to Monte Carlo.
According to a Cruise Critic member who is posting live reports from the ship on the Cruise Critic forums, the wave struck Serenity during the early hours of Saturday morning (April 26).
Member Keith1010 wrote: "… at around 1:30 AM a rogue wave likely hit the ship because three windows in the Crystal Dining Room were blown in and of course water also came in."
Crystal confirmed the report to Cruise Critic.
Crystal Serenity "was cruising the southern coast of Spain en route to Monte Carlo when the wave struck," a Crystal spokesperson said. "Temporary repairs were made to the windows during the night by the ship's crew. Most guests on board were unaware of any disturbance until an announcement was made to the entire ship to keep everyone abreast of the situation and to advise that dining room would not be open for breakfast or lunch.
"During the day, the windows were permanently fixed, the carpet was cleaned and dried, several other restaurants were open for breakfast and lunch, including Prego that was opened for lunch. The Crystal Dining Room resumed service for dinner."
According to Keith1010: "Portions of the carpeting got wet. A few tables are out of commission for the short term but given that several people are dining at other venues and even off the ship there are no issues.
"Again, kudos for the hard work of the Serenity crew and for working so hard to make this as transparent to the guests as possible," he said.
Crystal Serenity is currently on a 13-night Mediterranean cruise from Southampton to Rome.
