☞ Fin Theory 101:

● DRIVE & ACCELERATION: The larger the base, the more drive and acceleration. This is called the “BASE” measurement.

● DEPTH: This is the height of the fin. The more depth, the more holding effect the fin will have on the board. This is called the “Depth” measurement.

● PIVOT: The more sweep or rake on a fin, the less pivot feeling a board will have. The more upright, the more pivot. This is called the “Width/Rake” measurement.

● MATERIAL: Various materials are used for fins. RTM Honeycomb, Carbon, Carbon/Honeycomb, fiberglass and composite (polymer) are the main options available.
