The film shows a variety of ways of gybing a dinghy with the mainsheet fully let out, even for less experienced sailors. Gybing is tacking before the wind. The boat turns with its stern through the wind and the sail goes over to the other bow. On keel yachts, the so-called block gybe is common, where the mainsheet is pulled in by the blocks and then let out again after the mainsail has passed over. This is often taught on dinghies in license training. However, gybing with the mainsheet fully let out has long been popular on dinghies in particular, as it is easier and quicker. On the downwind course, you grab all parts of the long mainsheet tackle and pull the sail over by hand (sheet pull), or you steer so far beyond the downwind course that the mainsail passes over (oversteer), or you combine the two. Since the mainsail passing over the boat causes the boat to turn during all gybes, this must be compensated for by the rudder (counter rudder, support rudder). Summary: The film shows various boat paths and sailor actions when gybing a two-man dinghy with the sheet fully released. To practice, the sailors usually do a series of gybes in a snake shape. When moving from one curve to the next, a counter rudder occurs automatically. The active role of the foredeck crew in maintaining balance can also be seen. In the first part, the sailors gybe with different curve radii and in different wind strengths. The fully released mainsail is brought across either by pulling the sheet or by oversteering or by a combination of both. The changing of places in the boat with a change of hand on the sheet and tiller is shown in particular, something that is rarely seen in textbook series of images. The second part shows simple learning situations for less experienced sailors. Hand and place changes do not take place at first. Then the demands on boat control and spatial orientation increase. In the third part, other options for jibing with a released sheet are shown. The film also contains tips on equipment and trimming the boat to enable safer practice. Wind bands on the shrouds and a jib to indicate the wind direction are also generally helpful, as is the ability to reef the mainsail to sail with less wind pressure. Since almost all dinghies are built without one these days, a sailmaker can subsequently add a tying reef to the mainsail. © Hamburg, 2018 Authors: Gerhard Müller, formerly of the Department of Sports Science, University of Hamburg.
