Bells

Why Every Boater Needs a Marine Fog Bell

A marine bell may seem like a piece of old-world seamanship, but it remains a critical piece of safety equipment on the modern water. Under the International Regulations for Preventing Collisions at Sea — widely known as the 72 COLREGS — vessel bells are not optional on larger boats. Any vessel 20 meters or more in length is required to carry a bell in addition to a whistle, and those 100 meters or more must add a gong as well. These aren't bureaucratic formalities: when fog, heavy rain, or other conditions reduce visibility, sound signals become a vessel's primary means of communicating position and status to other mariners.

Under COLREGS Rule 35, a vessel at anchor must ring its bell rapidly for about five seconds at intervals of no more than one minute in restricted visibility. A vessel aground adds three distinct strokes before and after that rapid ring. These standardized signals allow other mariners to detect your vessel's scale and status through the dark of a foggy night — something no GPS app alone can replicate. Even smaller recreational vessels that aren't strictly required to carry a bell are wise to have one aboard as a reliable, battery-free backup signal device.

What to Look for in a Marine Bell

Not all bells are created equal for the marine environment. When shopping for a boat safety bell, keep these factors in mind:

• Material: Brass and chrome-plated brass are traditional choices that resist corrosion in saltwater and freshwater environments alike. Stainless steel options are also available for long-term durability.
• Tone and resonance: COLREGS Annex III specifies sound characteristics that compliant bells must meet. A quality bell produces a clear, carrying tone that can be heard at a meaningful distance.
• Mounting hardware: Look for bells that include a sturdy removable bracket and appropriate fasteners for clean, secure deck installation.
• Size: Bells commonly range from 6 inches to larger diameters. Vessel length requirements and deck space will guide your selection.
