Buoy

A buoy is a spherical, conical or barrel-shaped float which is anchored in general. Depending on the size and use of buoys are made of a hollow body made ​​of metal, plastic or solid cork. Buoys for mooring of vessels, etc. used as marking the location of anchors ( " buoy " ), as signal buoys for diving ( often made of inflatable bladders of foil or textile ). Buoys chains also serve as boundary markers, especially as marking the boundaries of protected areas, which may not be run over by watercraft.

To anchor the buoys on the basic heavy weights made ​​of concrete are often used. Is not a buoy anchored, it is called a drift buoy. Drifting buoys found in shipping, for example, as carriers of distress signal transmitters use ( emergency beacon ). To anchor can - as usual earlier - even a reasonably large block of natural stone are used in a hole is carved to pour about a ring beam by means of lead. To screw or a stiff Blechöse which must remain rotatable.

Serve as a navigation mark buoys for navigation, they are referred traffic laws as " tonne ".

Station

In the Exploration of the Sea Buoys serve as a floating instrument panel for the detection of oceanic and atmospheric data as well as for some other research purposes. Working alone in the project Argo several thousand robotic buoys on the oceans, who may be drop to 2000 meters deep and after surfacing a few days later, her measurements (water temperature, salinity ) on satellite radio.

Mooring buoy and mooring buoy

The advantages of mooring of vessels (eg, boats) to buoys opposite the anchors are:

• Less effort
• Independence from anchorage and water depth
• High security ( with adequate size and maintenance of the anchorage )
• Lying without long anchor rope or chain and thus better utilization of space (low schwojen )
• Conservation of the reason, as retraction and break out of the armature omitted.

For the use of such buoys is payable usually a fee.

Mooring lines

Buoys chain systems, such as the Albano - system for boat routes mark on water areas usually several parallel paths to perform synchronous sporting competitions. They float on the water surface of swimming pools, water bodies or waterways and serve the sports of swimming, rowing, canoeing.

In a pool The buoys are only about 6 cm in diameter very close to each other, are like pearls strung on a rope and secured against slipping, damp short waves a little and a swimmer can easily swim through underneath. Each rope is hooked to the pelvic start and end and can easily be obtained by winding on a round reel.

For boats buoys a chain are typically 10 m apart. For boats, such as when a team gives up, also can pull out the side, anchoring each buoy must be passed down at least to the maximum expected depth of an oar or paddle shock, before a continuous tense underwater cable ensures the linearity of the chain.

Mooring lines that delimit the exit zones of marinas or moorings or entry corridors for water sports ( kite surfers, water skiers, ...) as in lakes of areas with bathing for swimmers are anchored in the rule with stones on the ground, so also can form curved boundaries and are often more than 10 m apart.
