From True Ames

There is a reason this is the most iconic, functional and versatile single fin available...it works on just about anything! The Greenough 4-A has been our bread and butter for close to 40 years now, and is still the most popular single fin design there is.

A truly well-balanced fin...the full base coupled with the tapering, moderately flexible tip provides a solid amount of drive off the bottom, and an acute responsiveness through arcing turns. Designed for both speed generation and spending time surfing in the pocket, the 4-A is a fin that will hold when you need it to and release when the time is right. A fin that can do it all, throw one in your board and feel the success!

Our Volan fins are fine tuned with a precision foil as well as proper flex. They are handcrafted in Santa Barbara, CA and go through the strictest quality control. Fins made with Volan fiberglass and properly aligned for optimal weave orientation have very high performance flex characteristics — with the flex coming more from the body of the fin rather than just at the tip.

Fantastic fin for a 7’0 Christenson Huntsman

I went to San Diego for a full week to test out my 7’0 Hunstman egg fitted with this fin. From small 2’ onshore close outs, to chest/ shoulder high glassy mornings, the fin allows for pivotal turns when moved forward in the box, to long drawn out bottom turns when slid all the way back. Very stable,
just the right amount of looseness to where I could actually get a nice initial snap off my bottom turns. Plus, it looks cool!

This fin is awesome in my 6’10 smooth operator. loose and groovy feel but not too crazy, holds well in the tube. Volan material is nice and stiff with just the right flex. a great fin to add to your single fin quiver.
