Olsen Cruise Lines promises to get you "closer to the world’s most remote and picturesque destinations." In this case, right next to jagged walls of a VERY narrow canal.
According to Thrillist,
Fred. Olsen Cruise Lines is a Norwegian-owned company with four cruise ships based in the United Kingdom. The company's ship MS Braemar was sailing through the Corinth Canal in Greece, which, as previously mentioned, is just 24 meters wide at its narrowest point. The canal is four miles long and was built to allow for faster travel around the peninsula.
In the video above, thousands passengers on the ship were able to touch the sides at some points.
In order to accomplish the feat, the ship navigators required help from a small tug boat. This ship was the largest to ever successfully pass through the canal.
