Conical buoy

Buoys & beaconsCore

A triangular chart glyph identifies a conical buoy body.

What it means
A triangle standing on the small position circle is the paper-chart form of a conical buoy.
Why it matters
Body shape is only part of the mark. Confirm colour, topmark, light, and the applicable IALA region before deciding the safe side.
