Swept back Delta-wing profile


The StarFire sports a swept back Delta-wing profile and has a unique, inverted trailing edge designed to relieve drag. While competitor hydrofoils pull their wing tips forward, the StarFire’s extended wing tips were specifically designed to be fantastic stabilizers once the boat is up on plane. Another patented characteristic of the StarFire is its inverted trailing edge. Other hydrofoils have flat or convex trailing edges that extend outward and farther back behind the engine – creating drag, increasing fuel usage, and lowering top-end speed. StarFire’s inverted concave trailing edge relieves drag, increasing fuel economy and top-end speed!





As you can see, the StarFire’s overall profile was designed to be super-sleek. We don’t want you to hassle with clips, clamps, and bolt-on adapters during installation. We’re giving you a hydrofoil that installs in under 10 minutes with little effort. Because StarFire doesn’t require clips, clamps, or adapters it hugs the cavitation plate extremely close, preventing the excess drag other competitor hydrofoils experience due to their bulky, add-on installation adapters. Furthermore, we’ve patented the StarFire’s curvature which was perfectly optimized through the use of computational fluid dynamics analysis! The result of this optimized curvature is a hydrofoil that provides maximum performance every time it’s in the water!



The StarFire contains one of the most revolutionary design elements ever built into a hydrofoil – an Optional-Drill attachment feature. Highlighted in the yellow circles above are Optional-Drill points that boaters can use to bolt on the StarFire to the cavitation plate. Although we certainly don’t require or recommend bolting the StarFire onto the cavitation plate we felt it was important to satisfy every consumer’s installation preference, both Drill and No-Drill. However, for those boaters wanting to drill the cavitation plate, we’ve reduced the number of holes needed from the conventional 4 to only 2! That’s right, competition requires 4 holes to be drilled in the cavitation plate, while StarFire only needs 2 holes for installation! In the end, having options is better than not having options, and 2 holes is faster, easier, and less invasive than competition’s 4 holes!
