I was reading an old Pacific Longboard Mag and came across the Wavegrinder Fins. The article and the website www.wavegrinder.com claim that they reduce drag and create lift. They also claim to increase paddle speed with the foils.
Has anyone tried them or have an informed opinion. I was wondering about the application to downwinders and also the thruster set up for the short board SUP.
The blue image below is for the downwinder or longer SUP and the red image is for a thruster set up.
Not expensive either so may be worth an experiment if it doesn't get a roasting here.
Cheers for the feedback
