boating sound signals

While boating sound signals are rarely used in everyday boating, it does pay to know them. They prove to be especially useful once the fog gets too thick, for example, or in any other scenario wherein visual signals aren’t as effective.  

Sound signals for boats can be produced either by horns or even bells and depend on factors such as the vessel’s type, whether it’s power-driven, its current state and position, and possible danger. The said factors determine how these sound indicators should be used.

Continue reading in order to know every pertinent detail about maritime sound signals.

Signal Meaning
1 prolonged blast, not beyond 2 minutes For a motor-driven vessel to make known its presence in low-visibility conditions
2 prolonged blasts, not beyond two minutes with a 2-second interval between blasts Denotes a motor-driven vessel that’s free-floating plus not using its engine (e. g. not anchored or not tied to anything)
One prolonged blast followed by two short blasts every two minutes If the vessel is any of the following in low-visibility conditions:

  • A sailing or fishing boat
  • Towing vessel
  • Constrained by draft
  •   No commanding personnel present
  • Can’t maneuver properly

Ring the particular bell every 5 seconds every minute Vessel is at anchor in limited visibility
Ring the bell rapidly for 5 seconds every one minute. Afterward, the aft gong must be sounded for 5 seconds as well. Vessel that’s 100+ meters at anchor in limited visibility
1-second single short great time (US Inland Rules) Vessel wants to alter course to port
2 short blasts (US Inland Rules) Ship wants to alter course to starboard
3 brief blasts Vessel is operating astern propulsion (i. e. reversing)
5 short blasts Alarm or danger signal; vessel wants to know the other boat’s intent

Horn signals for boats are pretty straightforward, and the table above proves as much. Now that you know about them, it now falls in your hands to use them correctly and respond appropriately if another vessel happens in order to send them to you.

I want to make this clear that I prioritized the American inland rules and meanings of the sounds since that’s where I reside. Do take note that inland plus international rules overlap inside some of their signs and respective meanings because well.

If you happen to plan to boat in another country, like let’s say England, know that there are other shipping horn signals that they use.

Now that will we’ve touched on the particular topic of maritime guidelines abroad, it’s only right to tackle the confusion that arises sometimes when it comes to inland rules in the US compared to international ones.

For example, in international rules, the respective meanings for 1 short boost and two short blasts are reversed. Moreover, some boaters believe that three short blasts are the right signal to give when going astern, but to others, it’s actually prolonged.

I hope that with the above marine sound signals chart centering solely on US rules, you’ll be able to get a clearer, more reliable reference as an American boat owner or aspiring skipper.

What Do Boating Sound Signals Mean?

As can be readily construed from the table I shared above, the ship whistle signals and marine horn signals a watercraft sends can mean any of the following intentions listed in the correct column. Feel free in order to return to the table if you get confused about any of the respective meanings of the bells and boating horn signals.

Frequently Asked Questions

What are the legal requirements with regard to boating sound signals?

Boats that span less than 39 feet should carry a single horn or bell. Those that reach 40 ft to 65 feet should have two appropriate sound-signaling tools, namely a bell plus whistle. The tools should be audible within almost 1 km.  

When do you make sound alerts on your boat?

Boat car horn sounds as well since bell and gong ones should only be created to communicate to nearby vessels your intent, the boat’s current state, your position, and how far you are. In short, only make these sounds if a specific maritime scenario calls for them.

Conclusion

The numerous boating sound signals we’ve discussed here, as well as the particular variations that they have depending on where you’re cruising, proves there’s a solid system in place to keep sailors and ships safe. Overall, using sound signals isn’t the norm, especially if boaters are just navigating the waterways.

However , we can’t deny that their value doubly increases during an emergency, and if you’ve spent enough time sailing, you’ll agree that adopting a “better safe than sorry” attitude goes a long way. Remembering these signs is a good step in that direction.
