Tired of swinging?
The V-Shape FinDelta anchoring sail holds your boat steady with
less strain on your anchor rode.
When the wind increases, does your sailboat tack back and forth -- causing chafe, anchor strain and discomfort aboard? You can take control with our sail. As soon as your boat begins to swing, a fin directs a firm correcting force to a windward wing, and your boat is pushed back into alignment. Simple and effective. So effective, this advanced design has earned a U.S. patent and a "Best Choice" by Practical Sailor Magazine.
The FinDelta is designed to fit most boats. All you need is a way to haul it up. No backstay is necessary. Sheeted in firmly, it takes a taut three-dimensional shape that is very quiet. The sail features an international orange fin -- an added safety feature making your boat easy for others to see in rainy, foggy anchorages. Rigging only takes a minute or so.

To test the FinDelta concept, the NASA-funded Space Alliance Technology Outreach Program (SATOP) assigned the University of Central Florida Mechanical, Materials and Aerospace Engineering Department to do an analysis. The test verified that the FinDelta is up to 26 percent more effective at realigning a boat -- especially in those critical moments early in the swing. The fluid dynamics analysis screenshot at top of page shows how at only a 5-degree angle of attack the FinDelta forces air to the wing on one side while cutting it off entirely to the other.
The sail is made of heavy 7 oz. sailcloth strongly reinforced at all corners.
A free storage bag is included. Size: 6' 4" along the bottom; 6' 4" high (1.9 x 1.9 meters).
