The major difference between this race and Race 1 sailed on Friday is the two reaching legs. Sailing at 120° angle for 13 miles will be more of a challenge for both competitors.
Multihulls are not made to sail at such tight angles and they will be massively overpowered with their genoa. These are the most dangerous legs of this America’s Cup Match as the leeward hulls will want to bury itself underwater.
USA thanks to their huge width and natural lateral stability (righting moment) should feel comfortable meanwhile Alinghi will compensate that with their ballasts.
However the danger is the faster you go the riskier it is to nose dive. At this angle the leeward hull will want to go underwater and the trick is to know whether you bear away fast or come up hard to depower –
The crews will also have to be pretty quick to adapt their trim in order to avoid the windward hull to take off too much always synonymous of speed loss.
A very interesting day here in Valencia with hopefully both boats returning safely home tonight.
