The Fin
The RDM Twinzer is Derrick Disney's primary twinzer setup for the Midzr, Roe, and Egg models. This set features 70/30 foiled, stout rear fins with a wide base that seamlessly transitions into a fuller drop tip. The canard, working in conjunction with the precise rake and double foil of the rear fin, provides effortless drive and exceptional smoothness through turns. The RDM's double foiled canard fin features a wide base and striking curves similar to a Gephart 2 keel fin. This low-profile canard is available in multiple angles to achieve the optimal cant of approximately 13°, perfectly suited to the RDM Twinzer formula.

What people say
Effortless drive and smoothness through turns — stout, wide-base rear twins with a fuller drop tip, built around Disney's Midzr, Roe and Egg models.
The double-foiled canard is shaped with curves he likens to a Gephart 2 keel, working with the rear fin's rake and foil to smooth out the turn.
Run the full RDM set on a fuller-outlined twinzer egg or mid-length with matching canard boxes — it drives and holds through turns for surfers drawing lines and leaning into rail rather than flicking the tail. If you want a snappier twinzer for a shorter board, the DST Twinzer is the move, and if you want traditional keel-twin drive without canards, go Gephart 70/30 Keels.
More About This Fin
Derrick Disney's primary twinzer set, manufactured by True Ames in solid fiberglass with FCS- and Futures-compatible bases. The set pairs two wide-base rear twins, whose foil runs into a fuller drop tip, with a low-profile double-foiled canard set at a fixed cant; the canard is offered in multiple angles. It was designed around Disney's fuller-outlined Midzr, Roe and Egg board models and is meant for boards with matching canard boxes.
