“Junoplano” paved the way for the creation of fast cruising yachts with a canting keel as a righting element to increase comfort and safety as well as performance. The experimental purpose of “Junoplano” is obviously also a challenge. The canting keel system, together with the two bow-stern appendages, pivoting with a vertical axis (“Twin Foils”), in fact aims to solve the problem of the traditional keel, i.e., the conflict of interest between the two basic functions – righting and capacity. The result is the dream of every yachtsman: close haul or broad reach without side slip. Therefore, being able to count on the entire righting movement, it has been possible to design a hull with a lower waterline area, limiting the “hull resistance” effect of every displacement mono-hull. Form an aerodynamic viewpoint, the choice of pivoting mast means a sail plan with greater useful thrust and lower tilt effect, while the centre of gravity of mast and rig is about 3 m lower than a classical shrouded mast, which reduces lurching on the waves.
