si TNZ n’a qu’un seul AC45, c’est certainement parce que les Kiwis ont deux catas SL 33 sur lesquels ils peuvent naviguer autant qu’ils veulent et développer des ailes, des appendices et tout ce qu’ils souhaitent en vue de leur premier AC72. Ainsi, avec ces catamarans de moins de 10 mètres, ils contournent la règle qui n’autorise à chaque équipe que 30 jours de navigation sur des bateaux de plus de 10 mètres autres que des AC45 en 2012. 30 jours qu’il vaut évidemment mieux réserver à l’AC72 que chaque équipe pourra mettre à l’eau à partir du 1er juillet. Malins les Kiwis…
