Definitions

• the present invention has for its object to solve the problem mentioned in a completely different way.
• it is necessary to use a hitherto customary mast, and also a customary tree.
• the invention solves the problem by the characterizing features specified in the claim.
• the lower or middle part of the sail thus corresponds to the corresponding parts of the previous sails.
• the leeches of the sail sections preferably extend freely up to the top of the mast, where the main leech ends.
• the sailor gets a sail in his hand that combines the properties of different sized sails. In the event of gusts of wind or when there is a strong increase in wind, even up to a storm, there is an automatic partial freezing.
• FIG. 1 is a schematic side view of an embodiment of the sail according to the invention.
• Fig. 2 is a plan view of the sail of FIG. 1 in a purely schematic.
• the universal mainsail shown in the figures is identified as an overall sail with the reference number 1, with further sail areas divided off as so-called “compartments" 2 and
• a main figure of leech 4 trims the entire sail.
• Other independent sail edge figure 5 and 6 put the separate “compartments” 2 and 3 under trim pressure.
• the leeches 4 to 6 are under different trim tension, the one of the main leech 4 being the largest and that of the leech 6 the smallest.
• the sail is provided with Stauerlatte ⁇ 8 and held in the usual way between a mast 9 and a boom 10.
• the universal mainsail according to the invention automatically acts "reefing" with increasing wind strengths when the sail pressure becomes too great, the full sail size also being automatically restored when the wind subsides.
