Three passengers were injured when a “freak wave” struck the side of MSC Cruises’ ship MSC Divina.

In a statement, MSC Cruises said the incident happened at 11.40pm local time yesterday as the ship was sailing from San Juan in Puerto Rico to Nassau in the Bahamas.

The incident damaged a small cabin porthole.

The statement said: “One of two Mexican guests staying in the cabin sustained minor abrasions, while an Argentinean guest in another cabin slightly injured a finger when closing a balcony door.

“The safety and wellbeing of guests and crew are MSC Cruises’ number one priority, and onboard technicians immediately sealed the damaged porthole. As a further precaution, MSC Cruises has given alternative cabins to the guests from the affected cabin and those adjacent to it.”

The line said the ship will continue on its itinerary.
