# A buoy is mostly the part you never see

> A cardinal buoy's chain runs off the hem because it's as long as the water is deep — this print is about the part underneath, not the part that floats.

A cardinal buoy sits high on the chest, marked SC in block letters. Below it a chain runs the
full length of the shirt, four heavy links near the collar shrinking, link by link, until they
disappear off the hem.

Everything above the waterline is the small part of this object.

## What is actually printed on this shirt?

A buoy and its own mooring chain, drawn as one continuous vertical object rather than two.

The buoy sits in the usual place a print goes, high on the chest, but the chain is what carries it
the rest of the way down — collar to hem, in one run, instead of stopping where the buoy's shape
stops. Most things printed on a chest are self-contained shapes. A buoy on its chain isn't; the
chain is doing half the telling.

## Why does the chain run off the bottom edge instead of stopping at an anchor?

Because the chain is exactly as long as the water is deep, and cutting it off anywhere would be
inventing a depth nobody supplied.

A buoy's mooring is sized to the seabed it sits over — too short and it's dragged under on a
rising tide, too long and it wanders off station. There's no chain length that's correct for a
buoy in general, so drawing one that stops at a tidy anchor shape would be claiming to know a
number that isn't there. Running it off the hem says the honest thing instead: the chain keeps
going, further than the shirt does.

## Why do the links get smaller instead of staying a constant size?

Because that's the only way to show depth on a flat chest print with no horizon anywhere in it.

There's no ground plane here and no sky, so the usual tricks for distance don't apply. Four large
links shrinking to nothing does the same job [a scatter of birds at many sizes does with no sky
either](/stories/storm-petrel-scatter) — one shape repeated at a shrinking scale, and the eye
supplies the rest. Here it runs down instead of across, because a chain has a direction a flock of
birds doesn't.

## What decision actually separates a good buoy print from a flat one?

Whether the topmark reads as a shape or blurs into a smudge at print size.

A cardinal buoy's black cones — pointing up, down, both, or neither — tell a sailor which side of a
hazard is safe, and on a real buoy they're small enough that a print has to choose between
simplifying them into a clean silhouette or losing them into ink. The colour bands do less work at
this size than the topmark does, which is the opposite of how the same buoy reads at sea.

## Can I put a real buoy's number on it?

Not somebody else's without asking, though the buoy and its marking system are free to draw.

Cardinal and lateral marks are an international convention — nobody owns the shape of a cone or the
rule that black over black means keep to one side. What a harbour authority does own is the
identity of one specific buoy: its assigned number, painted on a particular piece of steel over a
particular hazard. If a real one is the point of the shirt, that's the authority's mark to license,
the same way [a boat's own name is somebody's to give permission
for](/stories/boat-name-transom). The invented SC sidesteps the question rather than answering
it.

## Does this work for anything other than a fishing mark?

Yes — any mooring is the same object underneath.

A private mooring buoy, a diver's shot line marker, a swim buoy anchored off a beach: a float sized
to be seen, tethered by whatever chain or line the depth needs. For somebody who moors their own
boat, or dives off one regularly, the print reads as their actual relationship to a specific patch
of water rather than a generic sea reference.

## How is this different from the shirt built around a life ring?

The two objects have opposite jobs, and the compositions are built to look opposite too.

A buoy's whole purpose is not moving — the chain runs off the hem here because staying on station
is the entire mechanism. [A life ring's whole purpose is being thrown](/stories/life-ring-open),
which is why that print draws it broken open at one quarter, mid-flight rather than moored. One is
a shape you tether down. The other is a shape you let go of.

## Does it print well?

Yes, as flat colour with a hard engraved line rather than a soft render.

Cream for the buoy body and rust orange for the bands keep it to two inks beyond the shirt, and the
chain links want drawing slightly larger and fewer than a photograph would show — fine hatching on
metal at this size fills in on fabric rather than reading as texture.

## How do I get one made?

Describe the mark at [JustOG](/) — the topmark, the bands, and how much chain to run. Pick a
direction, drag the crop frame, see it composited on the real garment, and it's made to order and
shipped.

Designs other people have published are in the [shop](/shop).

Below the last drawn link, chain the print doesn't show keeps going all the way to the seabed.
