※ An Explanation of a Product

As vessels are becoming more and more larger and their speed is becoming faster, a problem of the decline of propulsion efficiency and adjustment capability tends to occur owing to erosion made by cavitation. TWISTED SPADE TYPE can minimize the erosion of cavitation by minifying an incidence angle taking notice of the difference of angle of attack flow of the upper and lower sides of a propeller, being asymmetric TWIST-type up and down.
