Funnels are smoke stacks, of course. Chimneys for the diesel exhaust. In the days of steam, they were very tall, as tall as the ship itself sometimes, in order to direct the black soot and cinders away from the passengers. At the turn of the 20th century, funnels were a status symbol. The first to have four was Kaiser Wilhelm der Grosse in 1897. For two decades, four stacks would be a symbol of size and speed. They reflected the necessity for many boilers to produce the steam to power them across the Atlantic. The Titanic, the Mauritanea, the Lusitania and many more had four funnels, tilted at a rakish angle to communicate style and luxury. With so many funnels, intakes, coal bunkers, and equipment, the decks were a mess of mechanical objects with little room left for passengers. Eventually only three funnels were needed, although a fourth dummy funnel was sometimes added. Then two funnels and finally, one, allowing the interiors and the upper decks to open up. Here, the funnel is mostly disguised, wrapped by the Crown Viking Lounge on three sides with the climbing wall on the aft side. AT the top, where it is exposed, Royal Caribbean puts their crown and anchor symbol.
