Vortex size is also affected by proximity to the ground. If youre flying low enough to be in ground effect, the vortex isnt able to fully develop. This lateral movement takes place at a speed of about two or three knots. As at higher altitudes, the vortex movement near the ground is affected by crosswinds.

With as much as 25 knots of tailwind, we made the flight from Sodus to Alton Bay in only two hours. An observation of salt stains on my hangar floor ultimately led to the fire department hosing off the entire 4,800 foot long runway. Unfortunately, this also meant meager ground speeds topping out around 85 knots.

We routinely taxi at 1200 rpm due to the low spray…[we] can cruise at 10 knots” in displacement mode, something a Goose can’t do. Early on a speed restriction of 130 knots was applied as a flutter issue. This was resolved on the kit version and led to cruising at 50% power and 120 knots, which proved to be the Gweduck’s sweet spot.
