The frames are Galilean: at 200kt, relativistic corrections are at the one-in-a-trillion level.
The only frames that matter are i) that of the deck/concrete on which you stop, and ii) that of the moving air in which you are flying. The ship should be steaming relative to the wind so that its angled deck has a direct headwind of at least 30kt.
You can pick any other frame you'd like too; but you don't need to know what the energies are in any of those.
