I've been searching the web and I could not find any results for an independent Stingray Hydrofoil Stabilizer before and after performance test. Maybe if I asked nicely the good folks at Marine Dynamics Inc. might throw some real numbers my way. Although, perhaps the "magical cure-all" is a better and more profitable marketing approach. Keeping weight to a minimum, sufficient horsepower with power tilt trim along with a properly matched ss prop has always worked for us albeit quite a bit more expensive than an ugly whaletail is.
