Spar buoy

Buoys & beaconsCore

A long narrow chart glyph identifies a spar or spindle buoy.

What it means
A long narrow body leaning away from the small position circle is the paper-chart form of a spar or spindle buoy.
Why it matters
Spar form is neutral. Use the colour, topmark, light, and charted function to identify how to pass it.
