Ian Carmichael ("Jack") and his fiancée "Peggy" (Janette Scott) fall foul of her rather fastidious landlady and are soon looking for a house. As luck would have it, they discover a houseboat and for a mere £750 they have their dream home/yacht. Not long after moving in they meet their landlord "Watson" (Dennis Price) who wants to double the rent for their mooring. Extortionate, so he - a mechanic, encouraged by his pal "Sid" (Sidney James), decides to get the old tub mobile again, and off they go for some fun folics on the river with "Sandra" (Liz Fraser) along too. It's a very gently paced nautical comedy, this - it is all very predictable with some easy humour that pokes a bit of fun at the "Commodore Classes" whilst leaving you knowing just what is going to happen - and what the outcome will be, too. Noel Purcell is quite entertaining, Dennis Price gets a well deserved ducking and we certainly discover that life on the ocean waves is not for everyone.
