previous next

Explanation:

According to maritime rules, a powerboat anchored during restricted visibility must sound a prolonged blast (lasting 4 - 6 seconds) every 2 minutes. This helps other vessels detect its position. Option A matches this requirement. Option B has an incorrect time interval (5 minutes instead of 2). Option C (rapid bell - ringing) is for sailing vessels at anchor. Option D (2 prolonged blasts) is not the standard signal for a powerboat at anchor in restricted visibility.

Answer:

A. A prolonged blast every 2 minutes
