20% - 50% less resistance than other fins, results in virtually no loss of speed and thereby no added fuel consumption.
All fins are prepared for high efficiency in "Any Speed" - 2:1 size ratio, also "At Anchor".
The fins are made as a "one shot" vacuum injected vinylester process over pre-shaped core material in a closed mold method.
Designed with rowing and math layers to ensure maximum strength and minimum weight. Can even withstand small damages without totally disintegrating afterwards as traditional production methods often allows.
Fins have zero weight in water. US Patent US9527556 - Australian Patent AU2013335369 - Patent pending PCT/NO2013/050067
