A second video from Emirates Team New Zealand explaining how the hydraulic system will work and charge up to enable the the foiling monohull to raise and lower her foils and also how the system will charge up between tacks it takes 15 seconds in the shed.

The AC75 foil cant system has been in design for the past 6 months led by Emirates Team New Zealand Project Manager Peter ‘Brush’ Thomas, with PLC Engineer Ryan Thomas and Carsten Mueller who has led the hydraulic development.

“The design is essentially an electronically controlled hydraulic system which controls the 40 tonne hydraulic cylinders which lift and lower the foil arm,” explained Peter Thomas.

While this video will have many scratching their heads and longing for much simpler times, remember the AC75 is a third of the weight of her older monohull sister the International America's Cup Class, with more righting moment than the AC50, and will be the fastest monohull that ever sailed.

As the canting arm - being developed by Luna Rossa's design team and the foil canting system is a one-design supplied part to all competitors, there are no issues with showing how this mechanism works - unlike the usually highly secretive engineering and hydraulic systems which remain under the bonnet of most America's Cup Class yachts.
