    Background: Italian engineer, Glaugo Corbellini, after years of research, has designed and is testing a revolutionary new "slatted" sail.

    Mr. Corbellini, 60, of Grado, near Venice, has been sailing since he was 12, and over the last few years has used his sloop as a laboratory for his sail designs.

    He said he has always been interested in the problem of finding a sail which ensured full manoeuvring, even in the roughest weather.

    And the result of his work is this "slatted" design, which also has many other advantages over a conventional sail.

    It can be raised and taken down more easily, its aerodynamic return increases as the winds get stronger, and its most interesting characteristic is that the boom is fixed. The slats move with the wind and a yacht fitted with the sail needs only to be steered to do full 360 degree turns.

    This also means fewer crew members than with conventional sails.

    Mr. Corbellini tested his various designs measuring wind pressure and using wind test flags to test the flow across the sails.

    He has now patented his revolutionary new design and has put it into production.

    SYNOPSIS: This sloop is owned by Italian engineer, Glaugo Corbellini, of Grado, near Venice, and it is different from all the others because of its revolutionary new sail design.

    Mr. Corbellini has been trying for years to perfect a sail design that gave a Yacht full manoeuvring even in the roughest weather. He has used his sloop as a sailing laboratory. to test each of his designs. And he has finally settled on this venetian blind-type "slatted" sail.

    Using equipment to measure wind pressure, and flags to check the flow across the sails, this new sail could revolutionise sailing. The boom is fixed and the many slats move with the wind. When turning the yacht needs only to be steered.

    This eliminates the dramatic sweeping boom of a conventional yacht when it tacks. It also needs fewer crew members to sail it. But the new sail was designed to overcome many of the problems of sailing in rough weather. The sails can be raised and lowered more easily in a strong breeze, and their aerodynamic return is increased as windows get stronger. The angle between the wind and sail is no longer critical.

    Here the helmsman puts the sloop through a full turn. The sails are fixed in the centre, and the craft keeps a steady speed. Mr. Corbellini, who is sixty, has been sailing for forty-eight years. He says he decided to get to work on a rough weather sail design when he was stranded in port once because the winds were too strong to take out his yacht. Boating is his second life, after his engineering and electronics business, he says. Mr. Corbellini has patented the new design and has put it into production.
