Canadian Boating Practice Exam

When a vessel is anchored, it is required to produce sound signals to inform nearby vessels of its presence and location. Option A, one long blast every minute, is the sound signal made by a vessel under restricted visibility. Option B, three short blasts every minute, is the sound signal made when a vessel is being towed. Option D, continuous ringing, is used by small vessels such as canoes or kayaks. The correct option, C, is five seconds of rapid bell ringing every minute, which is the required sound signal for an anchored vessel.
