Two prolonged blasts of a ship's horn typically indicate that the vessel is operating in restricted visibility and is making a turn to starboard (right). This signal is part of the International Regulations for Preventing Collisions at Sea (COLREGs) and helps communicate the ship's intentions to other vessels nearby. It is essential for maintaining safety and awareness in foggy or low-visibility conditions.
You need to transmit the Morse letter D (-..) with either a fog horn or hitting a bell every 2 minutes. Long blasts need to be 3 times as long as short blasts. The space between blasts is as long as the duration of a short blast. So the sequence goes like this: Blow the horn or hit the bell for 6 seconds, wait for 2, hit it for 2 seconds, wait for 2 seconds, and hit it again for 2 seconds.
I intend to pass you on the starboard(right) 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.
Well, honey, three long blasts followed by two short blasts from a Great Lakes ship means they're backing up, just like your ex trying to come back into your life after they realize they messed up. So, keep your distance and let that ship do its thing before it ends up in hot water.
you better get off that ship!!Two short blasts means that the vessel intends to leave you on it's starboard side. If you are in international waters it means " I am altering my course to port"
passing on the port side from behind

It has several meanings depending on circumstances.A vessel not under command or restricted in its ability to manoeuvre, or constrained by her draught, or engaged in fishing, or towing or pushing, or a sailing vessel.
There are particular sound signals that are to be used when you first get underway. One prolonged blast signifies that you are about to get underway. If you are going to make way in reverse, you need to signal an additional 3 short blasts.
The sound signal of one prolonged blast followed by two short blasts every two minutes indicates that a vessel is restricted in its ability to maneuver. This signal is used to alert other vessels in the area of the restricted vessel's presence, especially in low visibility conditions like fog. It is important for nearby vessels to be cautious and maintain a safe distance from the restricted vessel.
