MetadataShow full item record
In the long history of mankind, there was no machinery, Since wind is an abundant power resource in the open sea, vessels and boats in fisheries, trade, and warfare were installed with sails for propulsion. For several hundred years, humans had always applied wind energy in most of their water-related activities. In the last hundred years, technologies on internal combustion engine have been enhanced. Promoted for active propulsion in water cruising, the engine practically replaced the functions of the sail, until the sails have become less visible especially in fisheries activities.
