Epsilon is a ROPAX ferry that operates for POLSCA Baltic Ferries on the Baltic Sea.
The Cartour Epsilon was delivered in 2011 to Sicilian ferry operator Caronte & Tourist.
In 2013, the Epsilon was chartered to Irish Ferries to expand their Dublin–Holyhead route, crossing the route twice a day from Tuesday to Saturday, opposite the Stena Superfast X, before running Dublin–Cherbourg from Saturday and returning to Dublin.

On 11 February 2016, Epsilon sustained damage to her cargo, after sailing into Storm Imogen while en route from Cherbourg to Dublin. Afloat.ie reported that the ship met steady forecasted wind speeds of 60 knots, with gusts of up to 105 knots (almost 200 km/h) at times.
Her charter ended on 4 December 2023, the ferry had already been sold to Unity Line.
MS Epsilon entered service with Polish operator Unity Line in January 2024 on the Świnoujście - Trelleborg route. On 30 January 2024 Epsilon collided with quay no.7 during mooring maneuvers at Trelleborg port in heavy fog. No human injuries were sustained, however the vessel had to be docked.
After the consolidation of Unity Line and Polferries under the POLSCA brand, the ship continued service on the same route with her new operator. In April 2026 she received the POLSCA livery.
The vessel has capacity for 500 passengers and 2860 lane metres.
