Windsurfing Fins
Since 1987, our staff has helped our customers choose literally thousands of fins to help them get the most performance, and fun out of their time spent on the water. Let us do the same for you. Call us. We’re your fin experts.
Some general thoughts on choosing a new fin:
The fins that come “stock” with today’s boards are significantly improved over even a few years ago. Often the stock fin will be just the ticket for most of the conditions that the board was intended for. However, to maximize the performance range of any board, you may want to add a second (or even third!) fin. In some cases the stock fin may be a bit small for the average sailor. Ask one of our fin experts for advice on adding another fin or two. It can often be the least expensive way to upgrade and expand the performance of your board.
When your fin is too big for the conditions, it will generate too much lift, reducing board control.
When your fin is too small, you will have problems going upwind or getting on a plane. And you will feel your tail slipping, or skidding sideway. Your ability to go upwind will be compromised.
Sailing in lighter wind conditions, such as freeriding, you can get away with 4-6 cm between each fin size. But in the waves or in hi-wind sailing 1-2 cm can make a big difference.
Here are a few things that are good to know about a fin:
Span (length): The dept of a fin is measured vertically from the base of the fin to the tip, excluding fin box.
Maximum cord length: The widest point on the fin. A fin that is wider will help get you planing earlier.
Rake angle: The angle a fin is from vertical. A fin with more rake is usually more maneuver-oriented and smaller than a more upright fin. Most surf and high wind fins have a pronounced rake angle. Larger, more upright fins offer better light air and upwind performance.
Trailing edge: The back edge of the fin.
