Although they are not required, all boats should carry whistles and they should be a part of every crewmember’s personal safety gear. Kahlenberg Industries, Inc., a manufacturer of marine equipment since 1895, designed and produced its first marine air horn nearly 80 years ago. Choose from 146 royalty-free Ship Fog Horn sounds, starting at 2, royalty-free and ready to use in your project. For personal use, a boat whistle is more effective than yelling when you need help. Instead of relying on a disposable canister of compressed gas, it can be refilled with compressed air using a bicycle pump. One interesting handheld horn is the EcoBlast™ Rechargeable Signal Air Horn. /rebates/2fhorns-whistles2f&252fhorns-whistles252f26tc3dbing-&idwestmarine&namewestmarine&ra2. This single bell horn measures 37 inches and provides a deep, classic brown note sound unlike typical high-pitched air horns. Coast Guard engineers have solved the problem turning the horn on and off by using an automatic fog detector. While most boat owners are familiar with manually sounding a fog signal when the fog lowers, human control is, of course, impossible at an unmanned site. Capable of producing 119 decibels of sound, they work great for signaling your intentions-and are a blast (pun intended) at sporting events! Fixed-mount trumpet horns, like those seen on larger boats generate sound by releasing compressed air, or in some cases by electronic means. Experience the low and powerful tone of a tugboat horn with the HornBlasters TUG-37. The reinstalled fog horn will be operated and maintained by volunteers. Handheld compressed gas horns consist of a canister of compressed gas that is attached to a small plastic trumpet. Marine signal horns are used to indicate your intentions to other boaters (“I am turning to port”, “I am aground”.) There are several designs of signal horns. Horns are required on boats from 39 to 65 feet in length.
