Explanation
Rule 35(a) requires a power-driven vessel making way in restricted visibility to sound one prolonged blast at intervals not exceeding 2 minutes. 'Making way' means the vessel is actually moving through the water, not merely underway. Compare to Rule 35(b): underway but stopped uses two prolonged blasts.
