It was decided that the ships would be true liners, their accommodations divided into three classes. For some reason it was also decided that the three bottom-most passenger decks would not have any portholes. It has been claimed that this made the ship's sleek hull shape, but that seems unlikely to be true as ships of similar length/width ratio have been built with windows along the entire hull. Whatever the shortcomings in their initial design, though, the new sisters were very advanced on the technological side. The most striking feature in the ships were their Turin polytechnic-designed funnels, which consisted of an intricate trellis-like pipework (instead of the traditional even surface) to allow wind to pass through the funnel, and a large smoke deflector fin on the top. Although much criticised, the funnel design proved to be highly effective in keeping smoke off the rear decks. The smoke deflectors became popular in ship design during the 1970s and 1980s, whereas the idea of allowing wind to pass though the funnel was picked up again in the late 1980s and is almost the norm in modern shipbuilding..
