Some sound signals that you should be familiar with are:
- Restricted Visibility
- One prolonged blast at intervals of not more than two minutes is the signal used by power-driven vessels when underway.
- One prolonged blast plus two short blasts at intervals of not more than two minutes is the signal used by sailboats under sail.
- One prolonged blast is a warning signal (for example, used when coming around a bend or exiting a slip).
- Five (or more) short, rapid blasts signal danger or signal that you do not understand or that you disagree with the other boater's intentions.
