The operator, part of Irish Continental Group, is planning to transfer its Isle of Inishmore ferry on to the busy cross-Channel route where it will compete with existing firms P&O Ferries and DFDS.
Services are due to begin in June 2021 with Irish Ferries planning to add more capacity on the Dover-Calais route in the “coming months”.
“We are very excited about launching our services on the best short sea ferry market in the world and we believe we can bring more choice for customers in the years ahead,” said Irish Ferries.
