Jeff Grennan has been working on the design of his templates for years.Over the last year NVS has been working with him to add a high performance foil in order to increase the flow and speed of his fins. The Grennan fins are part of the Specialty family.
Jeff's idea was to pair a narrow base with increased rake in order to decrease drag while retaining control down the line and through turns.And boy was he right; his template has become a favorite in the San Diego glider scene and is used by the likes of Skip Fry and Bob Mitsven as well a tons of others.

Product Construction
Apex Series - G10
Part of the NVS Apex G10 Construction; made with a solid piece of precision Foiled G10 Fiberglass for the ultimate in performance and durability. The combination of highly durable Construction and precision Foiling yield a fin that is stronger and has a more ideal flex pattern than your traditional Honeycomb or composite fins.
Additional Info
NVS Apex Series Fins
NVS Apex Series Fiberglass Fins: The Pinnacle of Performance.
Better Materials:
- Apex: Made using G10; an industrial grade fiberglass, which is manufactured to the highest quality standard. Made by heating special fibers with epoxy resin under intense pressure in order to make a perfect panel; they eliminated the errors which can occur by using a hand layup. By heating the fibers and resin under pressure NVS is left with the ideal resin to fiber ratio in order to maximize strength and decrease weight.
- Apex Flex: Made using Volan Fiberglass for increased flex through the body of the fin.
Better Foiling:
One of the main benefits to NVS' Apex line of fins is that each fin is cut on a CNC machine using the exact foil profiles NVS developed.
- SeriesIII: The benchmark of high performance. NVS uses a very specific foil that was derived from a series of NACA foils whose purpose was to increase laminar flow (speed) while decreasing turbulent flow (drag). This translates to a fin that allows for faster/easier generation of speed and has a wider angle of attack, which means you won’t lose as much speed while bottom turning or going through hard cutbacks.
- Concave: or inside foils are used on board where you want easier rail to rail transitions. Concave foils will generate more hold at slower speeds but will not be able to go as fast as flat foiled fins.
- Retro: Used on some longboard fins such as the Da Clutch and Gypsy which feature a more period appropriate foil to suite the classic board designs.
Better Manufacturing:
By using cutting edge CNC machines and precise designs they machine cut each fin in order to have the perfect foil and finish. All NVS fins are designed 100% in house using advanced 3D software.
This is what makes the Apex Series G10 fins the strongest most high performance fins in the world. Of course performing better than anything on the market isn’t enough for NVS, so they left these with a unique and sexy tree ring finish that is sure to turn heads.
