So, never land/ditch across swells, always along them. If only waves, land/ditch into the wind (which is probably into the waves also).
There is no "along them". Unless you can predict their velocity, and movement relative to the flight path. They are similar to the deck of the carrier, except not only do they move up and down, they travel sideways....so I'm told....
