Case study

The pictures tell you a recent story in simplified graphics. Note the fast speed of the windsurfer with FRPGear hydrofoil Fly-Fin, while the same windsurfer with a traditional fin can not even go. The secret of this dramatic difference is FRPGear Fly-Fin.

FRPGEAR Fly-Fin and traditional fin perform very similar during strong wind.

You can see on this picture Fly-Fin lifts the whole board up (not just the behind of the board). Water meets the Fly-Fin equipped board behind the mast—similar to the traditional fin board on the right. Notice that Fly-Fin sailor is standing in front of the foot straps. This indicates that Fly-Fin board goes faster with the wind and the sail feels light. 20 knots wind for Fly-Fin equipped board feels like 15 knots for a traditional fin board.

The wind died very fast when the traditional fin windsurfer was about a mile away.

Traditional fin makes it very difficult to go upwind if not on planing.

FRPGEAR’s Fly-Fin keeps you sailing well up wind at any wind speed.

The traditional fin sailor is walking back to the beach and fly-fin sailor is planing.

It is a good idea to have Fly-Fin while on vacation so you can have more planing days when vacation time is limited.

It is a good idea for windsurfing rentals to offer Fly-Fins in order to do more rental business during light-wind seasons.

Fly-Fin equipped windsurfer is faster compare to a kite foiler.

The sailor who goes home is using a traditional fin. The sailor who keeps planing is using Fly-Fin.

No need to use different boards for different wind conditions. Just use different Fly-Fins with your smallest board for better results.

Sailors who cannot get on planing are wondering why is one windsurfer still planing fast. People in the car cannot see Fly-Fin.

Fly-Fin looks simple but it took over 40 years to make it work right.

The pictures show carbon fiber exterior layer with UV epoxy coat. After abrasive use in sand you can easily refinish the surface by wet sanding and finished polishing.

Carbon material looks better compared to glass. Carbon delivers more stiffness.

Use links below to review discussions about Fly-Fin on independent forums. These are good Forums acting for non-profit and allow all the opinions. We found that some forums like these limit discussion about Fly-Fin——Some participants have 60000 posts. Do they have time to windsurf?

http://directwind.comEmotions driven French speaking forum with much fun in conversations but little technical specifics.—Typical American situation when it starts nice but ends vulgar.—A person from Canada is trying to look important in windsurfing. But still interesting to review.

Our picks:

1.—The best forum about windsurfing if you are looking for top experts in aero- and hydrodynamics. Very good source if you need a free engineering suggestion.

2.—This is not a very popular forum. This is why we consider this forum to be democratic. They will allow any posts for increase of popularity.

3. - very good discussion about frpgear Fly-Fin videos

4.—Also very technical German forum as expected.

5.—Very practical. While all forums in the world have been talking about Fly-Fin, this Bulgarian forum simply reverse engineered and made a working copy. Will see how it works.
