The Fin
Derrick Disney’s RDM canards, FCS compatible solid fiberglass in ivory — the lead fins of the RDM twinzer he runs on his Midzr, Roe and Egg models, sold as a pair.
A twinzer runs four fins, but not as a quad: each main fin gets a small canard set just ahead of and outside it. The canard sheds a vortex over the main fin, which lets the main fin hold at a steeper angle than it otherwise would. Canards are sold as a pair; the rear fins come separately or in the twinzer sets.
This template
The RDM canard is the wide-based one: 3.15" of base under 2.53" of depth, a low profile with a keel-like curve. Disney’s formula puts the canard at roughly 13° of total cant, which is why it comes in 0°, 4° and 9° — pick the angle that gets you there on your plugs.
Specifications
What people say
Fast and loose (but not too loose).
Effortless drive and exceptional smoothness through turns.
These are the front end of the twinzer, not a side-bite upgrade. On a mid-length twinzer like the Midzr or Roe Fish the canard and rear fin operate as a unit — the canard breaks water tension and sets up the flow, the rear fin drives off it. Run them with the RDM Twinzer rears as a matched set.
Replacement canard fins for Derrick Disney's RDM twinzer system, made by True Ames in solid fiberglass with an FCS-compatible base. The template uses a wide base similar to a Gephart 2 keel, a flat inside foil, and a 6.50 sq in area sized for Disney's mid-length twinzer boards (the smaller DST canard runs 4.79 sq in). Cant comes in 0°, 4°, and 9° options, chosen so canard plus rear-fin cant totals approximately 13°. They fit boards with purpose-built twinzer canard boxes such as Disney's Midzr Egg, Roe Fish, and Egg.
