135-145sqm mainsail 90sqm jib 200sqm code zero.

Ac75 hull material. The ground-breaking concept is achieved through the use of twin canting T-foils ballasted to provide righting. 207m plus 2m bowsprit. 1 10 Oct 2018 64 101 1112 1114b 125 1310 2011 231 1915 34 3574.

But the foils can serve another purpose too. AC75 Class Rule 91 Proposed amendment. Nowadays foils are commonplace but the engineering and sailing techniques needed to get the AC75 to fly are completely different from anything seen before.

The AC75 mainsail will have a different flying shape from the IACC monohulls sailed from 1992-2007 Americas Cups class and the hard wingsails used on the AC72 and AC50 in 2013 and 2017. 91 Except as permitted in Rules 95 and 96 the outermost layer of the hull foils excluding foil systems controlled by. The leeward skin is more curved and therefore the leech is further forward.

Americas Cup AC75 Class Rule specifies basalt in mould construction. In the case of the AC75 the rules Fischer says are actually very open. As explained in the article a year ago the hull of an AC75 in foiling mode should have zero lift zero heel and almost zero distance between the bottom of the hull and the water surface.

The requirements listed in Rule 64 material certificates are not required for FRP for which the only fibre content is glass fibre. Amend language to refer to the hull shell opposed to hull surface. Exceptions added to component in the maximum elastic modulus table.

THE AC75 AT A GLANCE. - Strict limitations on the number of components that can be built including hulls masts rudders foils and sails thus encouraging teams to do more RD in simulation and subsequently less physical construction and testing - Supplied foil arms and cant system to save design time and construction costs. With the AC75 sailing on its foil drag is dramatically reduced vast amounts of power can be generated and so speeds rapidly increase.
