Each themed cruise will feature a different pair of dancers appearing on five different ships from May to October, 2013. The professional dancers include: Ian Waite, Natalie Lowe, James and Ola Jordan, Pasha Kovalev, Robin Windsor, Camilla Dallerup, Kristina Rihanoff, Darren Bennett and Lilia Kopylova.
The cruises will be split between the Canary Islands and the Mediterranean and will be on Azura -- (whose godmother, Darcey Bussell, is also a judge on this year's show) -- Aurora, Ventura, Arcadia and Oceana.
Passengers will be able to see the costumes worn by the dancers, watch them perform, participate in the show -- and get judged by Revel Horwood.
It is the second year of P&O's hugely successful Strictly cruises, which all sail from Southampton and start from £1,179 for a 13-night Canary Islands cruise.
