The Ahi Twin is a performance oriented upright twin, designed by Duke Aipa, for his Dark Twinn model as well as other high performance twins and twinnies. The wide base provides loads of drive and the upright template and refined tip provide increased maneuverability over more classic twin fin outlines. These fins are ideal for increased speed and fluid rail to rail transitions.

G10 is made by compressing layers of fiberglass and epoxy resin and baking it an autoclave to have the maximum strength of any fiberglass available.
