In this week's "All Things Considered" (Sunday 7 June at 8.30am repeated Wednesday 10 June at 6.30pm) Roy Jenkins visits the world's largest floating bookshop. The 12,500 tonne vessel Logos Hope has been attracting thousands of visitors to Cardiff Bay this week, with a wide range of events.

Until a few years ago, she was a car ferry, plying between the Faroe Islands, the Shetlands and various Scandinavian ports. Now with a crew of 280 - from 50 different countries - all of them unpaid volunteers - she's a key tool in the work of the Christian mission organisation Operation Mobilisation.

Roy takes a whistle-stop tour of the ship to hear about its work and meets some of the families and crew to discover what life is like on board.
