Dave Rastovich Twin Keel's.
 
The Rasta Keel was designed by Australian free-surfing icon Dave Rastovich, as he developed his own refinements to the classic keel design, it is undoubtly based on the highly rated Sea Sheaperd Keels.  Incorporating a layer of natural fiber jute there is an undeniable organic aesthetic, while increasing the stability of the base and leading edge. Rasta is known for riding alternative boards and this is his go-to fin for down the line speed in any twin fin that suits a keel fin.
