Ireland's ICG has posted bigger profit for 2017 as volumes grew.
The London-listed owner of Irish Ferries, which also has feederships and ports, said net earnings were EUR 83.3m ($103m), against EUR 58.8m the year before.
Revenue grew to EUR 335.1m from EUR 325.4m.
Chairman John McGuckian said: "2017 was another successful year for the group, despite the headwinds of increased fuel costs and weaker sterling."
Group fuel costs increased by 25.2% to EUR 40.3m, against EUR 32.2m in 2016.
But trading conditions have remained favourable.
Irish Ferries recorded strong volume growth of 1.7% for passengers, 2.4% for cars and 0.5% for ro-ro freight.
In the container and terminal division, overall container volumes were up 5.9%, while port lifts were up 3%.
This year, car and passenger volumes have benefited from additional high speed ferry sailings.
Irish Ferries carried 35,600 cars in the first three months, up 9.1%, while the number of passengers carried increased to 135,500, up 4.5%, compared with the same period last year.
It transported 43,800 ro-ro units in that period, which is down 3.3% on the prior year.
