"Robert M. Gary"
I'm told the reason for this is because of the number of items a sea
plane can hit on take off and landing vs. a clean runway env.
Like the shoreline. Thud.
Granted this accident (1997) isn't a rental. Pilot/owner hired a CFI because
the plane had just been purchased - insurance requirement.
"The seaplane base operator reported that the CFI elected to use a shortened
portion of the lake for the takeoff run, and could have extended the takeoff
run by a half a mile by changing the takeoff heading by ten degrees."
We live near this seaplane base.
