In federal waters, vessels that are 20 meters (approximately 65.6 feet) or longer are required to carry both a bell and a horn. The bell is used to signal in restricted visibility, while the horn serves to communicate intentions and warn other vessels. Additionally, vessels under 12 meters (about 39.4 feet) must have a sound-producing device, but the requirements for a bell are not mandatory for them. These regulations are part of the International Regulations for Preventing Collisions at Sea (COLREGs).
Vessels greater than 20 meters in length are required to have a bell.
All vessels are required to have a sound producing device, such as a horn, whistle, or bell, that can be used to signal warnings or communicate with other vessels on the water.
Vessels greater than 20 meters in length are required to have a bell.
A whistle or bell, AND a horn audible for at least 1 mile.
Vessels 65.6 feet or more in length
On federally controlled waters, vessels that are 12 meters (39.4 feet) or more in length are required to carry a whistle or horn for signaling purposes but are not required to carry a bell. This includes power-driven vessels, sailing vessels, and other types of vessels within this size category. Smaller vessels, those less than 12 meters, are not mandated to carry a whistle or horn, but it is recommended for safety.
In Missouri state waters, all vessels that are 16 feet or longer are required to carry a whistle or a horn, but a bell is not a requirement for these vessels. This includes motorboats, sailboats, and other types of vessels within that size range. Smaller vessels, those under 16 feet, are not mandated to carry any sound-producing devices. However, it is recommended for safety purposes.
In federally controlled waters, vessels that are 12 meters (39.4 feet) or more in length are required to carry a whistle or horn and a bell. Additionally, vessels of 20 meters (65.6 feet) or more must have both a whistle and a bell on board to comply with navigation rules. These sound signaling devices are essential for communication and safety during navigation.
Vessels that are required to carry a whistle or horn but not a bell typically include recreational boats, such as small sailboats and motorboats under 20 meters in length. These vessels are often subject to specific regulations based on their size and type, which may not mandate the presence of a bell. Instead, a whistle or horn is used for signaling in situations where audible communication is necessary. Always check local regulations for any variations.
In Pennsylvania state waters, all vessels are required to carry some type of sound-producing device, such as a whistle, horn, or bell. This regulation applies to motorboats, sailboats, and other vessels, particularly those over a certain length. The sound-producing device is essential for signaling in situations where visibility is limited or to communicate with other vessels. Compliance with this requirement helps promote safety on the water.
In most navigational districts, commercial small craft are required to carry those items.
