* Data supplied is measured with instrumentation and under the supervision of engineers, and refers exclusively to optimal test conditions for configuration of the vessel at half load. A variety of factors such as the condition of the props, weight aboard, sea conditions, as well as air and water temperature may result in lower performance figures. During construction, production reserves the right to make modifications and take technical decisions without altering the basic concepts. The Cruising Speeds are chosen by the owner according to preference, the only limit being the maximum rotation speed maintenance time established for the engines, stated and recommended by the engine manufacturer.
