Title:
A WATER FRICTIONAL DRAG REDUCING STRUCTURE FOR THE WATERCRAFT
Document Type and Number:
WIPO Patent Application WO2005030568
Kind Code:
A3
Abstract:
The present invention relates to a structure that will reduce waterdrag for watercraft moving on the surface of water, thus will enable such watercraft to move at greater speed, consume less fuel and bear less action from waves. A water frictional drag reducing structure for the watercraft comprising:at least two rows of flat circular disks, each of flat circular disks is linked at the axis of center thereof, and the axes of center of the said flat circular disks are connected to hulls of the watercraft, or the axes of center of the said flat circular disks are linked to frames disposed between axis of center of the said flat circular disks, these frames disposed between axes of center of the said flat circular disks connected to the a hull of the watercraft moving on the surface of water in the form of symmetrical rows through a longitudinal axis of the hull of the watercraft.
