Thanks matey, I can't see them running both boats (but I hope they do!), I don't think they could muster 2 sets of staff!
The other thing I thought is, what happens to all the consumable stuff! i.e. the Ben wasn't taking passengers so wouldn't have had anything in the shop, any food &,  most importantly. the bar wouldn't have been stocked!! 
Have they transferred everything?
Will they carry it all back to Manxman tomorrow & then back again next week when it goes into drydock?
With a bit of luck I'll find out this afternoon!
