Inland Signs and Marks

• Classify a CEVNI board by its sign family, then use its exact symbol and scope to choose an early, observable action.
• Distinguish no entry, no overtaking, no passing, no berthing, no anchoring, no making fast and no damaging wash without collapsing them into one generic warning.
• Differentiate mandatory direction, side, crossing, stop, speed, sound, lookout, main-waterway and radiotelephone instructions.

A self-guided revision companion that explains essential concepts, then helps you practise and test them. It supports—but does not replace—recognised instruction, practical training, assessment or certification. Access is a one-time payment, not a subscription.
