MANDALA AK4 QUAD FIN SET - CLEAR FIBERGLASS
This is the original AK4 quad template that I cobbled together back in 2004. When I was a kid my favorite tri-fin was the Merrick template, which had the perfect balance of drive and release. I re-sized this template and altered the rake angle for all the quad fish I was shaping during the first Fish Renaissance. Since then, they've been working very well with the continually evolving family of Arctail Quads, Arc-Swallowtail Quads, Superchunks, and other iterations of the Mandala Mini Board.
