Wouldn't the one prolonged on be under inland rules? I this case, I believe its only 3 short blasts. Why am I wrong?

Inland Rule 34(g)

For International and Inland rules 3 short blasts on the whistle mean you are operating astern propulsion, so if your leaving the slip you would be operating astern propulsion therefore you need to sound 3 short blasts.

Is one prolonged blast for getting underway only covered under inland rules. Why would this not be one prolonged followed by three short for operating astern propulsion.

Rule 34(g) is inland only. "When a power driven vessel is leaving a dock or berth she shall sound one prolonged blast"

Doesn't specify anywhere that the vessel is "operating astern propulsion." Could've been worded better.

It states that "Your vessel is backing out of a slip"...that all but says directly that you are operating astern propulsion.

in practice its one prolonged to signal intent of exit from slip and 3 short to signal astern propulsion.... dumb question

Rule 34 (g) INLAND is what requires one prolonged blast when leaving a dock or berth. There is NO Rule 34 (g) International, and the question specifies INTERNATIONAL ONLY. The question is fine.
