The 36th America’s Cup, which will be held in Auckland (New Zealand) from January to march of 2021, he enters into the decisive phase of preparation of the equipment, with the launch of the second generation of the monohulls, AC75, that can change everything seen until now in the sailing of high competition.

In these moments, both challenging, the INEOS UK británic, the American Magic american, and the Luna Rossa Italian, as the defending champion, Emirates Team New Zealand, trained with the AC75 first generation.

it Is expected that both in the World Series, which will be held also in Auckland from 17 to 20 December, as in the Prada Cup or tournament challenging and will challenge the defender, which will be held from 15 January to 22 February, because it will compete with units of second-generation.

it was in New Zealand, in August 2012, when the candle high competition took a dramatic turn when a catamaran of 72 feet (21,95 m of length) ‘flying’ materially in the Hauraki gulf. The Emirates Team New Zealand had brought ‘foiling’ (navigate with ailerons) to the Copa America and forever changing the high-level competitions,

Since then, the increase in the performance of the boats of the America’s Cup has been greater than at any time in the 170 year history of the event.

Six years later, in 2018, the publication of the rule class AC75 marked the beginning of a new era of navigation. Today the ‘foils'(spoilers) are common, but the techniques of engineering and navigation necessary for the AC75 ‘fly’ are completely different from anything I have seen before.

For starters, the AC75 is has a length greater: 75 feet (22,90 m) and a beam of 16 feet (4,90 meters), but is also lightweight, which is vital, because the AC75 is designed for ‘flying’ (to sail above the surface of the water)

there is Also a new concept that raises the boat: the Foil Cant Arms (spoiler arm moveable) moves under or out of the water to provide the boat to provide the support it needs to stay high.

Some parts of the AC75 as the tube of the mast, the rig, the arms of the aileron and its hydraulic system are all common components. However, there are still a number of areas with which designers can experiment to find a winning edge in the races.

A new evolution of this America’s Cup is the sailing of two skins. This double candle combines with the mast to form a wing, generating the power that the AC75 needs to rise and gain speed.

The system of wing mobile is a new technology, a unit of hydraulic power driven by batteries that suministram the energy to lift and lower aluminium arms immensely strong and heavy.

as the boat begins to turn, the mobile system is active, placing a wing of hydropower in the water, and rising up in another, where its weight becomes a burden.

at The end of the arms of the ailerons are the secret weapons of the teams – the wings of aluminum. Apart from the basic rules that govern the dimensions and the weight, it is a territory open to the designers, and each team has given them a different way. Some have taken the form of a whale’s tail and other gull wings, different settings and revolutionary.
