A vessel may communicate its lack of understanding by using visual signals, such as displaying a specific flag or light pattern, or by sounding its horn in a particular sequence. Additionally, it might attempt to establish radio communication, using phrases like "I do not understand" or "Repeat your intentions." If these methods are ineffective, the vessel may alter its course or speed to indicate uncertainty regarding the other vessel's actions.

its easy sound signal
When vessels in sight of one another are approaching each other and from any cause either vessel 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 such doubt by giving at least five short and rapid blasts on the whistle

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.
The stand-on vessel has the duty to maintain its course and speed when encountering a give-way vessel, which is required to take action to avoid a collision. The stand-on vessel should be prepared to take evasive action if it becomes apparent that a collision cannot be avoided. It is essential for the stand-on vessel to remain aware of its surroundings and communicate its intentions if necessary. Overall, the stand-on vessel should prioritize safety while following the navigation rules.
It stands for United States Ship
If you encounter a vessel displaying only a visible white light, it is most likely a power-driven vessel that is underway. In this situation, rules of the road require that you keep to the starboard side and pass at a safe distance. Be cautious and keep a lookout for any other lights displayed by the vessel to determine their course and intentions.
Three short blasts of a horn on a boat typically indicate that the vessel is operating in reverse. This signal is used to communicate the boat's intentions to other vessels in the vicinity, ensuring safety and preventing collisions. It’s important for all boaters to understand these sound signals as part of navigational rules.
Depending on which side they intend to pass you on, they should give you and audible horn blast. One blast indicates passing on the starboard and tow blasts indicate passing on the port. Remember to return the same audible horn signal to let them know that you heard them and are aware of their intentions. One blast from them gets one blast from you and so on. The vessel being passed will remain the Stand - on vessel, which means you do not alter your course or speed. They, being the Give-way vessel must alter speed and course to pass.
