Floatplanes are not noted for being good gliders. I refined the gliding technique for the 182 amphibian as a part of preparing to train the owner. The most safe glide, for the purpose of landing at the bottom was 85 KIAS, with a 12 degree glide path angle. It's kinda like a helicopter autorotation, you gotta time the flare perfectly. But, once you perfect it, it works the same way onto a runway as on to the water.
The Teal, and a Lake Amphibian both glide nicely at 80 MPH. But done right, you can get very pleasing power off landings. These two aircraft, being flying boats, are best landed on the step, rather than full stall landings. Floatplanes like full stall landings, flying boats, much less so. The Lake is a delightful flying plane, much better than the ill informed rumours which seem to circulate. The Teal is not as nice to fly, but is superior to the Lake on the water in a number of ways - it's always a compromise....
