Fins prevent squirreling and keep the wakeboard going in the direction it is pointed. By creating drag, the fins pull down the tail of the board to track in the water. The shape and size of the fin will have a huge impact in how it performs. A large fin creates more drag than a smaller fin because it is digging into the water more, making the board more stable. A shallower fin will allow for quicker reaction times and sharper turns.
Fin Configuration
The most important thing to consider is the fin configuration. There
are singles (one center fin on both ends), quads (four fins, with two on each end and no center fin), six fins, and molded-in fins (with a removable center fin).
- Twin Tip
The twin tip with a single center fin will give the most predictable ride. Turns will be easier to initiate, and the fins will be less likely to catch than on a multi-fin board. In rough water, single fins should be larger. - Quad Tips
Quads give tight, quick turns, but will feel looser than other fin styles during turn initiations. - Six Fins
or added control and hold, helping the rider to accelerate through turns, six fins come in handy. Because there are six fins in this configuration, shorter fins can be used even in rough water. - Molded-In Fins
Molded-in fins maximize the edge hold because of the big edge channel/fin, allowing the rider to remove the center fin for sliders or smooth water, yet retain control.
FINS AND WATER CONDITIONS
Some riders prefer to choose their fins based on water conditions. If so, consider that in rough water, a larger fin gives the rider more traction and control in the water. In smooth water, the freedom of movement of a smaller, shallower fin is preferred by most riders.
FIN MATERIALS
The fastest fins are made of machined aluminum. Since the material is so structurally strong, the fins can be smaller without flexing. Fins are also made of fiberglass, which provide a steady and predictable ride.
