Captain Dominic Read runs the Magna Carta, a five-star floating B&B in Windsor. Stephen Bull and Joanna Harris are bowled over by the former working barge and Rayne and Chris Deal are impressed with the girth of their berth. But Trish and Tom Brock Morgan struggle to detect that five-star feel in their cabin. Over an afternoon of drumming, the group unleash their inner rock gods, with Trish really letting rip. The Captain hosts dinner on board, but his thunder is slightly stolen when one of the guests makes an epic rousing speech of epic proportions. At breakfast, the guests observe that it's Captain Dom's staff putting in the hard graft, and a cracked teapot almost rocks the boat. Come feedback time, one couple's criticism takes the wind from Dominic's sails.
