There are seven fins listed here. They are each rated for the type of action that they do best, which is listed above.

Measurements

Each of the fins was measured and weighed for dimensions, area, and weight.

H= Height     

Height is key in determining surface area in fins. Distribution of surface area is critical in determining how well a fin tracks

B= Base   

The base width is another key factor contributing to surface area and tracking.  Typically a broader base tracks straighter, while a narrower base allows for more pivot. The shape of the fin tip can also contribute to ease of pivot.

R= Rake

The rake in a fin is one of the most critical elements dictating fin performance. The  “leading edge curve” and “foil” combine for efficiency cutting through the water and reduction of drag. More upright fins will pivot (downwind fins), but may increase drag or snag sea grasses.

A= Area

calculated by:   A= Base x Width x Height  (adjustments are made to compensate for curve)

*GENERALLY SPEAKING, more surface area in a fin offers more resistance to pitch & roll.  The placement of that surface area relative to the bottom of your board results in varying levels of tracking &/or drag.  More area deeper in the water = more tracking + deeper draft (increased drag).  More area closer to the board = less tracking + shallower draft (less drag).

Wt= Weight

Fin weight is dictated by construction method.  Fiberglass lay-ups are durable but heavy.  Foam core + carbon construction is more expensive, but optimize strength to weight ratios.

 

Flatwater Fin Descriptions

#’s correspond to fins  (see rating scale at top of page)

1. Triangle Cutaway (Med) : H= 8.85”  B= 7.75”  R= 6.87”  A= 52.3  Wt= 10.25 oz

This fin is great for heavier paddlers or paddlers that have less experience with regard to stroke technique. The generous area deeper in the water column provides a tremendous amount of tracking even in the choppiest of conditions. The swept back leading edge help to mitigate the drag resulting from the fins height.

Best for: beginner to intermediate paddlers, paddlers +190 lbs, or for extremely choppy conditions.

 

2. “The Runner” by John Becker   H=8.25” B= 7.02”  A= 58.93” Wt= 13.125 oz

A great fin to maximize strokes per side.  Works well in a narrower board to aid in  reduction of pitch & roll. Available now!

 

3.Triangle Cutaway (small):  H= 7.85”  B= 7.25”  R= 6.68”  A= 44.0”   Wt= 10.125oz

One of the best selling race fins, the Triangle Cutaway sm complements a wide range of paddlers.  The swept back leading edge reduces the fins profile, while the well distributed surface area helps to maximize strokes per side.  This fin tracks well in all conditions, helping to maximize paddle stroke efficiency.

Best for: paddlers of all levels that race in a broad range of conditions.

 

4. Karen Wrenn fin:  H= 8.125”  B= 7.87” R= 4.0” A= 39.91” Wt= 9 oz

The most agile of the flat water fins, the Karen Wrenn fin relies on a big base to track well in

a variety of conditions.  The low volume fin tip is crucial for quick buoy turns, and riding waves

to the finish in ocean races.

 

Best for: technical races with lots of buoy turns, or racing in and out of the surf

 

5. Byron Kurt fin:  H= 9.0” B= 7.25” R= 3.44” A= 43.2”  Wt= 8.75oz

This is a great all around fin that fits all levels of experience. The Byron Kurt fin is the best ocean race fin, outside of the specialty downwind fins.  The broad base allows for great tracking in all conditions, without being so tight that you can’t surf in for the win.  

Best for: technical racing with buoy turns and ocean races through the surf

 

6. Jamie Mitchell fin:  H= 9.25”  B= 6.0”  R= 3.25”  A= 40.0”  Wt= 7oz

This more upright fin template allows easier directional changes in the open ocean.  The nimble feel makes it a great choice for downwind runs, ocean racing, or hanging ten in the surf.

7. Keel:  H= 6.438”  B= 7.0”  R= 5.875”  A= 44.4”  Wt= 8.5 oz

The race Keel fin keeps a low profile with a highly raked leading edge and a lot of surface area

packed in close to the board.  By concentrating the area shallow in the water column, the Keel minimizes drag and maximizes speed.  The Keel fin tracks best in flat water conditions, however more experienced paddlers can use stroke technique to compensate while capitalizing with the added speed. The added agility comes in handy in races with multiple buoy turns.

Best for: flat water conditions, or intermediate/ experienced paddlers that have a good grasp of stroke technique.
