Emirates Team New Zealand today tested a wingsail on one of the two SL33's on the Waitemata Harbour.
She launched at 0800hrs this morning, spent about 40 minutes testing and making adjustments off Westhaven marina and her club, Royal New Zealand Yacht Squadron, before being towed (quicker due to the wind direction requiring her to gybe down the harbour) by her tender for a testing session off Takapuna.
She returned later in the day before the offshore wind increased substantially.
The wingsail appeared to be different from the AC45 in profile, and from what could be observed is a two element wing.
Emirates Team NZ are believed to be the first team, entered in the 34th America's Cup to test a wingsail outside of the AC45's.
We hope to have some on water photos later
