My vessel is stopped and making no way through the water.

Blazon: Azure, a saltire argent
Single-flag meaning: My vessel is stopped and making no way through the water.
Drawn from: The blazon above and nothing else. The description specifies content and never specifies drawing — which is the whole argument of the Heraldry entry. Where this differs from an official chart, the difference is the blazon’s ambiguity.
