Welcome to the Irish Ferries Enthusiasts forum.
IOI left Birkenhead at lunch time and has being doing some fancy circles in the mouth of the river mersey since then. Take a look at her AIS
Oscar heading North, just passed Curracloe, ais destination is Milford Haven, probably on way to Liverpool.
When the ships come out of liverpool drydock they have to wait a while while the bunders heat up before they can proceed on full power. IOI was in Dublin for Stocking prior to traveling to Rosslare overnight.
