AC45 F Yachts Prepare for First Foiling Fleet Races in Portsmouth
New Rudder and Daggerboard Foils

July, 2015



Emirates Team New Zealand's AC45F on the crane in Portsmouth, providing a good view of her appendages.  The ACWS July 25-26 will mark the debut of standardized one-design foils in competition for the AC45F Class, the foiling variant of the AC45.  Note angled daggerboard (in retracted position, right of center) and t-rudder (facing camera at center).  Scroll down for close-ups of the parts.
