( 3 Fin Set ) FCS Compatible: What do you get when you combine a tri fin setup with some classic keel twin fin inspiration? .....The Mackie Mini Keel Thruster! These wide based keel designs with shallow depth create a thruster setup that is designed to provide maximum drive and projection. The keel shape side fins, combined with the slightly smaller trailer design will provide plenty of hold and will also give you some serious spring off the bottom wide tail surf craft. Especially suited for wider tailed surf craft, the shallow draw of these fins will reduce drag and allow for tremendous down the line speed.
- Rear trailer fin has slightly less rake and less base length in order to loosen things up slightly
- Front fins have a flat inside foil, rear fin has a standard 50/50 foil
- Solid fiberglass construction, flat matte finish
