These keel fins were designed to be an ideal template for high performance fishes.
The idea was to marry the classic keel outline with more modern, high performance characteristics. This template pairs beautifully with most twin fins and performance fishes.
Tried a bunch of different fin setups for my 5’9”Machado Sunday. Nothing really felt fantastic and I almost sold her. Threw large Marlins in and bam, it really came to life, becoming a magic board. The quality of manufacturing and stiffness of this keel are fantastic. Also took a couple rock bumps with zero damage. Highly recommended.
