Let's find out how the hydraulics work and what they control on board Luna Rossa, with department head Massimiliano Carbone, Davide Pescuma and Nicolas Starc. Oleodynamic systems are certainly nothing new in the nautical world, but those in an America's Cup foiling yacht require unprecedented levels of perfection, and thus a team of highly specialized technicians who are always ready to innovate and look ahead. They will explain the three main systems on board, the power and forces involved, and the importance of a constant control. The AC75's hydraulic systems, where oil is pushed at a pressure way higher than ordinary industrial pressure, are subject to enormous stresses. To ensure that there are no leaks or malfunctions, technicians perform detailed checks, several times a day, both when the boat is on shore and also during training sessions on the water, monitoring flows and balances on their PCs.
