The sweep, or rake, is how far the front edge of a fin arcs backwards. Rake or sweep angle is a measurement that determines how far back the fin curves in relation to its base. Fins with a small rake (large offset) help propel the board, are very stable and predictable but are not ideal for making sharp fast turns.
How is fin Rake measured?
The fin's base length is measured at the widest point of the fin, where the fin meets the bottom of the board. The base length determines the board's speed and drive. Fins contribute more speed and greater drive with longer base lengths.
