Kahlenberg Air Horns Come Down In Size There is an informal tradition at boat shows, where at the close of the last day of the show, when its time to break down the exhibits and untie the boats, everyone blows their boats horns. It is a fun thing we all enjoy after days of talking to people walking the docks. At the fall Newport show some years back, my former trawler, Growler, was on hand representing the latest example of the Zimmerman 36. Steve Zimmerman was on board to show the boat and explain its value to potential buyers intrigued by the idea of a Downeast-style cruising boat. At the close of the show when the noisy bellow of horns began, Steve went to the helm and pushed the horn button. Nothing. The horn just clicked. Over the course of owning Growler I replaced that horn three times, finally removing it altogether, and I relied on a handheld air horn I kept at the helm. Lobster boats can be wet when the conditions are just so, and I guess it wasnt a horn-friendly platform.
