One prolonged and two short blasts is 'D' in Morse signals. It is a signal to be used in restricted visibility by a vessel not under command[NUC], a vessel restricted in her ability to manoeuvre[RAM], a vessel constrained by her draught, a sailing vessel, a vessel engaged in fishing and a vessel engaged in towing or pushing another vessel.
They are indicating a dangerous situation exists
They intend to pass starboard to starboard side.
Two short horn blasts from another vessel typically indicate that the vessel is maneuvering to overtake or pass you on your port (left) side. This is a signal used to communicate intentions between vessels to ensure safe navigation and avoid collisions. It’s important to respond appropriately by maintaining your course and speed, allowing the overtaking vessel to pass safely.
3 short blasts
Means it's about to turn to port.
Two short horn blasts from another vessel typically indicate that the vessel intends to overtake you on your starboard side. This is a communication signal used in maritime navigation to ensure safe passing between vessels. It’s important for both parties to understand these signals to maintain safety and avoid collisions. Always respond appropriately to such signals to ensure clear intentions are communicated.
Two short blasts from another vessel typically indicate that the vessel is intending to overtake or pass on the starboard (right) side. This is part of the navigational signals used to communicate intentions between vessels to ensure safety at sea. It's important for mariners to understand these signals to avoid collisions. Always refer to the International Regulations for Preventing Collisions at Sea (COLREGs) for detailed guidance on sound signals.
Rules of the RoadSound and light signalsRule 34Maneuvering and Warning SignalsInternational (Signals of Action)(a.) When vessels are in sight of one another, a power driven vessel underway, when maneuvering as authorized or required by these rules, shall indicate that maneuver by the following signals on her whistle.-One short blast to mean "I AM altering my course to starboard";-Two short blasts to mean "I AM altering my course to port";-Three short blasts to mean "I AM operating astern propulsion".Inland (Signals of intent)(a) When a power driven vessels are in sight of one another and meeting or crossing at a distance within half a mile of each other, each vessel underway, when maneuvering as authorized or required by these rules:(i) Shall indicate that maneuver by the following signals on her whistle: one short blast to mean "I intend to leave you on my port side" (turning to starboard.); two short blast to mean "I intend to leave you on my starboard" (turning to port); and three short blasts to mean "I amoperating astern propulsion"(This is the ONLY action in Inland)Read more: What_do_two_short_horn_blasts_from_another_vessel_mean_in_a_meeting_situation
In the Navy, it means there is an eminent collision.With all due respect, this is an incorrect answer.From the 1972 Convention of International Regulations for Preventing Collisions at Sea.InternationalSounds and Light signalsRule 34(D) When vessels are in sight of one another and from any cause either vessels fails to understand the intentions or actions of the other, or is in doubt whether sufficient action is being taken by the other to avoid collision, the vessel in doubt SHALL immediately indicate the doubt by giving at least 5 short and rapid blasts of the whistle.
