I was sketching a glass of red wine and I got thinking about the glass as a vessel. After some time down a google-rabbit-hole, I landed on the nautical term under way. Under way is used when a vessel is not anchored or fixed to anything. Making way is used when the vessel is in movement in water. Under way is also used any time the vessel is in water, no matter whether the vessel is moving or still. Only needing to satisfy the condition not anchored. It is possible for a vessel to be under way, but not making way.
For example, if the engine failed, when the vessel was at sea. In that situation, you would frame a sentence, ‘The vessel is under way, but not making way.’ I’m struck by this definition as a metaphor to existentialism.

Is your vessel making way?
