As Gitana 18 and the Kiwi 's AC75 debut, speculation grows over a late challenger for AC38

Two big launches at opposite ends of the world. On top, the 32m Ultim trimaran Gitana 18 headed out from her base in Lorient on the west coast of France for her maiden sail. Down under the Kiwis slipped their dock lines in Auckland to take their newly reconfigured AC75 out for its first sail. Both are big steps forward, both were carefully choreographed affairs and both represent the first steps in two new generations at the very leading edge of the sport. Matt Sheahan reports on these and considers whether there may be a late entry into the 38th America's Cup. Plus, another helping of Docktalk.
