Among the rugged commercial designs are rotary-actuated rack-and-pinion steering, robust pumps and waste treatment, lifesaving and electrical systems. On the electrical side, Aquila possesses a specialized cascading bus system. When the larger of the two generators (27 kW) is operating, the yacht has enough electrical power to run every appliance. "We've [also] got 6 kW of inverters aboard driven by two large alternators that eliminate the need to run a genset during most crossings," Taricco said. Switching to the smaller generator limits the number of appliances the crew may run. The Jacuzzi won't turn on, for example. But when the yacht plugs into shore power, whether it is in South America, North America or wherever, you are good to go. Another compelling facet of the electrical system is the sophisticated Allen Bradley programmable logic controller, which turns on the 64's running lights and any pump on the boat; it also monitors current draws and trends in exhaust temperatures and performs many other functions. "From the electronics to the electricals, we have emergency and backup systems backing up the emergency systems."
