Booking SailRail via Liverpool?

[bangor-toad]

It's time to book another trip and as I'm a bit bored of flying, it's worth looking at SailRail. To fit in with actual work requirements I'd like to take the overnight Liverpool(Birkenhead) to Belfast Stena ferry. (On 30th March)

Whilst I can see all of the other SailRail ferry combinations, I can't get any tickets to show for this particular ferry. Does anyone know if these tickets are available or has there been some odd, ill thought out, restriction put on them which actually prevents thier sale (again)?
Does anyone know which booking sites might actually be able to sell me this ticket?

Cheers,
Mr Toad

Try the Arriva Trains Wales website for booking: it could offer me a Chester-Birkenhead-Belfast ticket for your date (Chester was just a starting point chosen at random) although only for the day sailing (or for Chester-Birkenhead-Holyhead-Dublin-Belfast). The Scotrail site comes up with the same.
