Dehavillanddriver,
I'm not certainly going to get into a debate about long, greaser, short and hot landings as this is outside my sphere of expertise (pity Dick Smith didn't do the same).
However, I must reiterate that weight of the vehicle has no effect on the aquaplaning speed, according to the experiments conducted by NASA. Whether the mass (weight) of your acft is partially supported by the lift of the wings, this should not affect the aquaplaning speed of the acft...according to the theory I was taught.
