Britain's rowers have fared well at the previous two World Cups this season, placing second overall in Sydney and first at Eton Dorney, however the field is set to be much bigger on the Rotsee.
Olympic champions in the four from London 2012 Alex Gregory, Pete Reed and Andrew Triggs Hodge headline the leading of two British men's eights entered with 650 rowers from 43 nations set to take part in Lucerne.
Britain sit top of the overall World Cup points table with Helen Glover and Polly Swann and Frances Houghton and Victoria Meyer Laker leaders in the women's pair and double scull respectively.
And, with next month's World Championships in South Korea fast approaching, performance director Tanner is expecting the racing in Lucerne to be the hardest of the season so far.
He said: "Lucerne will be our toughest test in this post Olympic season with a strong entry and World Championship selection at stake. It's a great chance for our rowers to step up again after a solid season so far."
