What people say
Combines a tri fin setup with classic keel twin fin inspiration — the shallow depth reduces drag for tremendous down the line speed and projection, and the side fins give serious spring off the bottom for wide tail surf craft.
Reach for this on a wide-tailed board with thruster boxes when you want keel speed and spring off the bottom but more hold than a twin gives. If you'd rather slice long, drawn-out two-fin arcs, the Sidecut Fish Keel is the call — this set trades some of that loose glide for projection and control.
More About This Fin
The Mackie Mini Keel Thruster is a three-fin set designed by Mick Mackie and made by True Ames, sold here in the Futures-compatible solid fiberglass version. The two side fins use a wide base, minimal depth, and a flat inside foil, while the rear trailer is slightly smaller with less rake and a shorter base. The set is intended for wide-tailed fish and hybrid grovelers fitted with thruster boxes.
