Raw SVG originals of the Pirate Party logo; source:

original: http://press.piratpartiet.se/stock-footage-logo/pressbilder/
Shrunk logo to its primitives.
Shrunk a bit by moving the decimal point.
Rescaled to a 10k origo-centered viewBox. Extracted mast rect path.
Round to integers. Rejoin mast to avoid painter's algorithm rounding errors.
Folded a v segment into the z one.
Pure black actually seems to be the logo intention.
