I was once told by my brilliant boss Krazy Bill, that the Cessna 185 if it floated AND got airborn: It will climb!
( Ca 10 to 15% overloaded he figured, depending on floats, Edo or Caps)
AS opposed to the the Otter that was unsinkable and if You got it on the step overloaded would stay in ground effect and refuse to climb!
Key to this drift is ACTUAL weight , ground effect and the guaranteed effect of OEI.
