Nearing a blind bend in a channel, what sound signal should you give?

One prolonged blast.

  1. Five short blasts
  2. One prolonged blast ✔
  3. Two short blasts

Why: Inland Rule 34(e) says a vessel nearing a bend where other boats may be hidden sounds one prolonged blast. Any approaching vessel that hears it answers with a prolonged blast.

Huh, didn't know that: In fog, a power-driven vessel making way sounds one prolonged blast at intervals of no more than 2 minutes.
