@davidships: that is the same as I found but I can add: 33.600 kW, 22.5 knots. That's all. In the past the FSB-yard had nice datasheets on the website.

Not a lot yet.
50400gt** 15120nt 10000dwt
194.0 loa x 31.8 x ??m

Four diesels geared to two cpp, but no details found

**At launching Irish Ferries said 54985gt

I'm surprised to see that she has a lower hold. Is that much used on the Dublin - Holyhead run? Perhaps it will be used more on her Cherbourg runs

Thank you Gena Anfimov for the inside W.B. YEATS pictures. But do anyone know the full dimensions (loa/lbp x b x dr x d, GT, NT, dwt) of this vessel and what is in the engineroom (engine builder, type, power)? A datasheet is not found on the internet (so far....).
