Aids to Navigation

Where is the safe, marked channel in relation to a pair of red and green buoys?

Answer

Between the red and green buoys

The navigable channel lies between the red and green lateral buoys. Staying between them keeps you in the deeper, marked water and clear of the hazards the buoys guard.
