When Morning Winds Had Not Yet Come

[M. Warrens]

I liked the flow of it, and personally I like abrupt endings. A suggestion I do have however would be for the second to last line:

Now trucks arrive. Their floodlights shine,
and men pour out as well as fumes.
But I untie my skiff, unknown,
and slip away to sea: alone.

instead of but, what about

Now trucks arrive. Their floodlights shine,
and men pour out as well as fumes.
So I untie my skiff, unknown,
and slip away to sea: alone

Though that might change your original meaning for the ending lines. Either way I like this one.
