Well, I´m into fins, right now. so, anybody made or use an "arc" type fin? I don´t think that I dreamed this fin... i´m not sure, but i think that this fins was used in the sixties. or may be in my designs dreams..
nobody meet this fin.. ? It´s like an arch, but soften and flaten, thinner, with rounded corners. the bases can be smaller or bigger than the "top".. with a vertical "elypse" hole in the middle of each base, i think lesser drag will be
