Former Team USA CEO and skipper Jimmy Spithill will take the wheel of Team Australia's “Flying Roo” foiling catamaran in SailGP's Dubai regatta on Dec. 9-10 while friend and countryman Tom Slingsby is on paternity leave. Slingsby's wife, Helena, is expecting the couple's first child. Spithill, a two-time America's Cup champion, is available to fill in for Slingsby after leaving Team USA prior to its sale to a private American group on Wednesday.
