The Science Behind Wing Sails

Revolutionary Design

ISTEC’s wing technology represents one of the most significant innovations in sailing over the last century. The system combines advanced aerodynamics with practical sailing solutions.

Wing geometry

Compared with its predecessor, the external dimensions of the new hybrid wing are far more compact. The most striking element of the new wing is the combination of a long, continuous top sail and a shorter lower sail layer. This way, the top sail forms a single-sail section at the trailing edge. The outcome of this design is the combination of a dynamic-pressure wing and a single-skin wing. The characteristics of this hybrid have many advantages that we will look at here in more detail.
