StingRay Hydrofoil Stabilizer

StingRay Hydrofoil Stabilizer

For most boats 40hp and up.

Eliminates bow rise, porpoising and bouncing. Significantly improves planing time, top speed, handling and safety. Unlike simple curved or flat planing aids, the StingRay™ actually creates lift. By raising more of the hull out of the water, reduces wetted area, thereby reducing drag. Greatly improves safety by allowing better visibility to the driver and passengers. Gives tremendous banking and cornering ability, no uncontrolled sliding or pitch-out.


The StingRay™ eliminates the need for troublesome trim tabs. Its patented high-tech shape causes water to flow over its surface, thus hydrodynamically creating upward thrust pressure on the underside surface. Scientific principles go to work the moment the propeller starts turning. Upward pressure lifts the hull, resulting in less drag since less of the boat is in the water. StingRay’s wings then stabilize the water pressure, keeping the boat stable and safer.


Now made with SPEED-XP™, an extreme performance hydrophilic material, making the world’s fastest hydrofoil stabilizer even faster!


SPEED-XP™ is a clear hydrophilic (water-absorbing) material that is thermally bonded to the base polymer material of the hydrofoil. The surface of this material is hard when dry and looks like a new wax job, however the “magic” of its performance is released when the surface becomes wet…SPEED-XP™ acts like a microscopic sponge when wet and will bind a very thin layer of water to the surface of the hydrofoil. The result is running water on water - a dramatic reduction in hydrodynamic drag and improved performance.


With a StingRay™ Hydrofoil Stabilizer, you’re up on plane in less than half the time it normally takes.
When it comes to getting a boat out of the hole, nothing else comes close. Water skiers are amazed at the difference. They’re up and skiing faster and easier than ever before. What’s more, the smoother wake makes skiing more enjoyable for beginners and experts alike.


Eliminates Chinewalking
By their very design, “V” bottom boats are susceptible to chinewalking. This dangerous side-to-side rocking lessens control and performance. Again, the StingRay’s™ wings go to work. The stabilizing action balances the boat to keep it upright and moving forward without a hassle.


StingRay™ stops a boat from porpoising
Porpoising is the name given to the forward and back motion some boats make while riding on the water. Picture a porpoise leaping through the water and you get the idea. It may be fine for them, but it’s murder on a boat’s performance, comfort and safety. This pounding causes many people to ride only in the back of the boat. StingRay™ corrects this action, providing you with more comfort, safety and performance.


Installation is quick and easy. All the hardware you need is included: four bolts, four self-locking nuts, four stainless steel washers, and four rubber washers. Simply drill four (4) quarter-inch holes in the cavitation plate on the lower drive unit and bolt the StingRay™ on. Pre-drilled holes in the StingRay™ serve as a guide for drilling the four holes. Place the StingRay™ on top of the cavitation plate, insert the bolts from the bottom up. Place the rubber washers on the bottom side and the stainless steel washers between the top of the unit and the self-locking nuts. Use a socket wrench to tighten the nuts. In a matter of minutes you’re ready to enjoy unmatched performance. Available in Black (pictured), Grey or White.
