The Arcadian is a river cruise vessel.
River day cruises are day excursions ranging from 30 minutes to a full day. They can be on boats carrying as few as 10 people or as many as a few hundred. Such a cruise is typically based in a city with a river flowing through the centre (e.g., Amsterdam, Bangkok, London, Paris) or an area of natural beauty, such as on the Hudson River, Rhine, or Thames.
River cruise ships with accommodation facilities offer longer cruises.
According to Douglas Ward, “A river cruise represents life in the slow lane, sailing along at a gentle pace, soaking up the scenery, with plentiful opportunities to explore riverside towns and cities en route. It is a supremely calming experience, an antidote to the pressures of life in a fast-paced world, in surroundings that are comfortable without being fussy or pretentious, with good food and enjoyable company.”
River cruising is a major tourist industry in many parts of the world.
