Stampfli Express - a 24-seater, 131-foot rowing boat is the longest in the world. The boat is all set to be a part of the Paris 2024 Olympic torch relay on Sunday. Just days before the start of the Olympic Games, the impressive shell will take 23 rowers and an Olympic torch bearer down a section of the River Marne, just east of Paris. It will not be a part of the official competition - rowers are only allowed to compete alone or in teams of two, four or eight in the Olympic Games.
