Rent Sink or Swim: Series (1982)

Peter Davison headlines this well-remembered BBC sitcom, starring alongside 'Hustle' stalwart Robert Glenister in his TV debut. They play brothers Brian and Steve Webber, whose attempt to strike out in business involves a soggy narrowboat and a dubious decision to ply the Thameside tourist trade. Unfortunately, Steve is as loutish and lazy as Brian is charming and ambitious - and the latter finds both his enthusiasm and his relationship with idealistic girlfriend Sonia (Sara Corper) severely hampered by his brother's persistent presence!
