I've heard of pilots landing on sandbars so short that they skip in on the water. I can't figure out how they take off if the sandbars are so short.
Takeoff is usually shorter than landing. So when landing these guys will use the water which will get them slow enough and hit the sanbars that are enough to finish rollout but also long enough for short field take off.
Yep those are the guys from Big Rock and Long Props. Great DVD, amazing the places they get in and out of.
BTW - I had my first expieriance on floats. Frikking awesome and man is that water hard. You really feel it.
