The initial one-year sponsorship deal includes ITV4 TV coverage, the chance to engage with 150,000 spectators every season and a PR platform.
The Airwaves Pro campaign also includes an interactive website at where sports professionals including rugby player Lewis Moody and England cricketer Liam Plunkett share their opinions about their favourite extreme sports.
Toby Baker, Wrigley's marketing director, said: "Over the past two years, Wrigley's Airwaves relationship with Ducati GSE Racing has granted us a broad range of benefits and our new relationship with Claygate Powerboat will enhance this. Many Airwaves consumers are thrill seekers, and our continued association with extreme sports allows us to bring Airwaves brand communications to life."
Mel Streek, joint managing director at Airwaves Claygate Powerboat racing, said: "Powerboat racing is one of the most exciting sports on the water and the support of Airwaves will help us to take the sport to a whole new level."
Last month, Wrigley shortlisted three agencies for its £100m global creative account, ending its relationship with Leo Burnett and Grey. The finalists include Omnicom Group's DDB, Publicis Groupe's Saatchi & Saatchi and Interpublic Group's DraftFCB.
