The CF Series was designed for reliable performance in a variety of conditions and is a favorite amongst the Captain Fin team. The side fins have a wide base that narrows out at the top of the template. This provides drive and speed while the slightly more narrow tip makes it more responsive. The rake allows for drawn out turns and the slightly smaller center fin gives you that release off the top. If you can only have one set of fins, the best selling CF Series is a great choice!
