I suppose it has to do with how many frames of reference you're juggling in a task/profession. With boats, others mentioned that wind provides its own frame, and there are separate words still for "left" and "right" in that frame.
Then there's space, where it gets even more fun, as the relevant frames - the ship, the orbit (or the "centre of gravity" of everything pulling on you) - are completely independent. That is, your orientation doesn't matter for the travel direction. Now, not only "right" and "left" are ambiguous - but also "up", "down", "forward" and "backward".
When in orbit, you have "prograde" and "retrograde" to refer to the velocity vector's direction and its opposite; if we dub that "forward" and "backward", then "radial" and "antiradial" are "down" and "up" (i.e. towards / away from the center of orbited body), and then "normal", "antinormal" for "left" and "right", which you can get from the cross product of "forward" and "up".
