The 1997 Dutch built vessel was first launched onto the central corridor route between Dublin-Holyhead but was transferred to the southern service after the introduction of Ulysses in 2001.

Rosslare-Pembroke Dock sailings only began in 1980, firstly operated by the B+I Line which competed with rival operators Sealink / British Rail (now Stena Line) on services running out of Fishguard.

This route was well established having started operations in 1906 and in an era when the railway companies (in this case the Great Western Railway) developed and owned the ports plus the operation of shipping services on the Irish Sea.
