You might want to hold your breath while this — now record-breaking — cruise ship squeezes through a tight canal.

A ship from Fred. Olsen Cruise Lines, named Braemar, became the longest boat to navigate its way through the Corinth Canal last week, CNN reported.

The ship is 22.5 meters (just under 74 feet) wide and 195.82 meters (about 642.5 feet) long. It weighs 24,344 gross tons and carried approximately 929 passengers while it sailed through the waterway that separates mainland Greece from the Peloponnese and connects the Gulf of Corinth with the Aegean Sea.

Additionally, according to Britannica, the width of the canal is around 25 meters (82 feet) at the water’s surface and is 6.3 kilometers (3.9 miles) long. The bottom of the canal only measures 22 meters (about 72 feet) wide.

“Guests on board Braemar able to get so close to the edges of the Corinth Canal that they could almost touch the sides, we know that this will be a holiday that they will never forget,” said Clare Ward, director of product and customer service for Fred. Olsen Cruise Lines, in a statement.

“This is such an exciting sailing and tremendous milestone in Fred. Olsen's 171-year history, and we are thrilled to have been able to share it with our guests,” Ward added. “We have already had an exceptionally high interest in our second Corinth Canal cruise in Spring 2021 and we can’t wait to do it all over again.”

The Braemar was sailing on a sold-out, 25-night Corinth Canal & Greek Islands cruise at the time it broke this impressive record, according to the statement by Fred. Olsen Cruise Lines. The next voyage is slated for mid-April of 2021.
