HABER 800C4 - self course-keeping sailing yacht We have developed a system of separately operated centerboards that allow you to achieve full directional stability on nearly any course and under any sailing conditions. Simultaneously, we have been working on additional solutions concerning gaff rigging. They increase the HABER 800’s ability to sail in heavy storm conditions on the sea. All these features make HABER 800 a unique, efficient and comfortable yacht with particularly small draught, a yacht which is suitable for longer journeys. It is for cruising on shallow inland waters as well as on the open sea.
