How the ferry grew up: Ro-pax ferries are bigger than ever, but how did the industry manage to increase their scale, while ensuring they can still safely navigate narrow harbours and operate in all weathers?

The article discusses the increase in size and capabilities of ro-pax ferries over the past 60 years. Despite their larger size, these ferries are still able to navigate narrow harbors and operate in all weather conditions. The industry's desire for larger vessels with more capacity and better facilities has driven the development of technical advancements in ship outfitting and equipment. These advancements include access equipment, stern access ramps, bow thrusters, variable pitch propellers, improved bridge controls, closed-circuit TV sensors, and azimuthing propellers. These developments have allowed for the safe and precise handling of large ferries, even in extreme weather conditions. [Extracted from the article]
