Which practice should be avoided under Rule 21 — Definitions (Lights)?
A
Not recognizing the cylinder day shape.
B
Confusing the arcs of visibility for different light types.
C
Making short blasts too long (2-3 s) — that is neither short nor prolonged, so it is wrong.
D
Sounding bell and gong simultaneously — at anchor in fog they go in succession (bell forward, then gong aft).
