多少世纪以来,风帆一直作为船舶的主要动力受人珍爱。但在十九世纪末叶,开始推广使用船用螺旋桨、蒸汽机和柴油机后,风帆受到冲击,帆船一时受到了冷落。近年来,为了节约能源和开发新能源,许多国家对风帆重又产生了浓厚兴趣,进行了一系列的试验和研究,获得了喜人成果,风帆重又枯木逢春,跨入了新的历史时代。古帆古帆就其性能来说,有直帆(“死”帆)、纵帆(“活”帆)和多桅多帆之分。 For many centuries, windsurfing has been cherished as a major force for ships. However, after the promotion of the use of marine propellers, steam engines, and diesel engines in the late 19th century, the sails were hit and the sailboats fell off. In recent years, in order to save energy and develop new energy sources, many countries have renewed their interest in sailing. They have conducted a series of experiments and research and achieved gratifying results. The sails are heavy and dead wood, and they have entered a new historical era. In terms of its performance, Gufan Gufan has straight sails (“dead” sails), vertical sails (“living” sails), and multiple sails.
