Just so you all know, a "Folk Special" has not been arranged for several reasons, as Gnomad has pointed out:-

A. There is no bar on board.
B. There is no toilet on board(3 hours at sea someone is going to want one)

and the bugger didn't mention

C. The engine noise in rather distracting and would diminish the singing somewhat.

Maybe next year there will another more suitable vessel when he and I can whisk you off to Staithes in comfort, nay luxury.
