An abacus is the value of a continuum variable according to the couple TWS/TWA.This could concern the value from a captor, from the heell, or from the obvious wind.The abacuses give target values of setting. They are represented by a succession of curves, differentiated by the putting step of this value. The difference between Sailect and Abacuses is that the Sailects represent a distinct element of the boat configuration. The abacuses and the Sailects can be overlayed in creation mode or during display.
