The company's Aurora Botnia ferry also transported more private vehicles, up 126% on the 2021 result to 55,661 units.
On the freight front, Wasaline carried 22,191 ro-ro cargo units between Umeå and Vaasa, an 4.4% year-on-year increase.
"We have a historical year behind us in many ways. It was the first whole operational year for Aurora Botnia, and the ship and its crew have exceeded all our expectations. We have continuously improved our offering and grown our share in all segments," Peter Ståhlberg, Managing Director of Wasaline, commented.
He furthered, "We were also able to reduce energy consumption by 21% per trip and our CO2-emissions by 19.6%. The strong financial result enables future investments in actions that benefit the environment. We are also on track to becoming climate neutral by 2030."
