Cosmic Keel

Interstellar Speed & Drive. 

Pure, unadulterated down-the-line projection. The Cosmic Keel is built for wide swallowtails, open point walls, and surfers who want to fly past flat sections without fighting the board. Designed with an extended base and low-aspect foil, it maximizes surface engagement along the rail to convert wave energy into raw forward momentum.

Laid up in 35 layers solid fiberglass to smooth out bumpy surface chatter, this fin delivers unshakeable hold at high speeds. It’s not meant for hacking tight, vertical tail pivots in the pocket—it’s designed to bury the rail, draw out massive, unbroken carves, and carry effortless glide all the way through to the inside.
