Seaplane Landing Question

Hi,

Probably a silly questio, but I was wondering about how seaplanes land in a
sea with waves running fairly close together ?

e.g., does the pilot try to put down parallel to the wave motion (this would
be along the trough of the wave) or does he
attempt to go perpendicular to the trough on landing ?

My "guess" is that the first is correct, but if so, wouldn't this tend to
flip him over easily) ?

The second would be analogous to the term "pitch-poling" used for sailboats
if they are flipped fore and aft by heading directly into a breaking wave.

Any explanations would be appreciated.

Thanks,
bob
