After their two previous nautical outings Griff Rhys-Jones, Dara O Briain and Rory McGrath return for a third one. Having previously recreated the famous journey of Victorian author Jerome K Jerome, and come perilously close to trading blows over Griff's prized yacht The Undina, 2009 sees the trio let loose on a variety of vessels in Rory's home county of Cornwall. Setting off from Plymouth with a plan to make it all the way to the Isles of Scilly, the three men are hampered by the fact that Rory is in charge of getting the boat, a subject he unfortunately knows nothing about. When their first vessel nearly kills them they are forced to beg, borrow and steal boats for the rest of the journey. En route they manage to crash into one harbour, charm their way on board a round the world racing yacht, do their bit for lobster repopulation, lend their voices to an amateur production of Pirates of Penzance and, true to form, indulge their competitive spirit (with a little help from an Olympic gold medal winner).
