A horn cleat is the traditional design, featuring two “horns” extending parallel to the deck or the axis of the spar, attached to a flat surface or a spar, and resembling an anvil. A cam cleat in which one or two spring-loaded cams pinch the rope, allowing the rope to be adjusted easily, and quickly released when under load.
Initially, small boats were fitted with bells and anchored. The first true bell buoy was developed in 1852 by Lieutenant Brown, who worked at the Lighthouse Establishment. He took a buoy and constructed a mount for the bell, under which he placed a plate with radial grooves on which a cannonball rolled and, moved by the swell, struck the bell. [7]
In most horns it also determines the pitch of the sound. When vibrated by the diaphragm, the column of air in the horn vibrates in standing waves. The length of the horn determines the wavelength of the sound waves generated, and thus the fundamental frequency (pitch) of the note produced by the horn. The longer the horn, the lower the pitch.
On the smallest surface vessels, such as a sport fishing boat, the flying bridge may have controls permitting the ship to be piloted from the flying bridge, but will lack the full range of controls of the pilot house. On larger small vessels, the flying bridge may actually be enclosed, in which case it is more properly called an "upper pilot ...
The vuvuzela / v uː v uː ˈ z ɛ l ə / is a horn, with an inexpensive injection-moulded plastic shell about 65 centimetres (2 ft) long, which produces a loud monotone note, typically around B♭ 3 [2] (the first B♭ below middle C). [3] Some models are made in two parts to facilitate storage, and this design also allows pitch variation.
