Just see what happens when you are trying to launch/retrieve and someone goes past the ramp 'on the plane'.
I would respectfully suggest you go 'off the plane' when passing ramps.
As I launch and retrieve solo, I can tell you that having craft go past 'on the plane' and thus creating a healthy bow-wave, is a pain in the a## and does nothing to make operations easier or safer.
