Finferries, Innamo

The latest ferry of Finferries, Innamo, operates in the Turku Archipelago. The ferry operates daily between the Nauvo main island and Seili, Innamo (giving the ferry its name), Ahvensaari (known for the old limestone quarry) and three other islands. The ferry began to operate on 1 May 2023. The ferry’s nitrogen emissions are low thanks to the urea-utilizing catalyst, so the vessel complies with the Tier III emissions of the IMO. The vessel was built at the Oy HL-Metal Ab shipyard in Parainen. Comatec implemented the electrical designs for all systems of the vessel. Follow the ferry here.

Starting point and goals:

  • Very fast timetable (construction period less than 12 months).
