spar buoy การใช้

• In 1962 the FLIP ( Floating Instrument Platform ), a 355-foot spar buoy, was first deployed.
• It is aligned in an east-west direction and is demarcated by a white spar buoy, marked " Koserow Steingrund N . ".
• This was made apparent when a pair of spar buoys marking the entrance to a shallow fishing channel appeared ahead of " Missouri ".
• The Pioneer Buoys are spar buoys anchored to the bottom, with custom electronics attached to the mooring lines monitoring data from sondes, temperature sensor strings, and other sensors as needed for research purposes.
• When flipped, most of the ballast for the platform is provided by water at depths below the influence of surface waves, hence " FLIP " is stable and mostly immune to wave action similar to a spar buoy.
• This effect is minimised if a small diameter spar buoy is used as the primary buoy to tension the line, as it will tend to react less to the waves, with a large volume safety buoy on a short tether, which will prevent the spar buoy from being dragged down if the tension gets too much.

• When within range, a " hookman " jumped atop the whale's head and stabbed it with a 35-cm-long, 22.5-cm-wide stainless steel hook attached to a heavy line of with a bamboo spar buoy at the end of it  at Camiguin, they harpooned it with a toggle-headed grommet harpoon with a wooden shaft similar to the " dolphin irons " used by American whalemen in the mid-19th century, which in turn was either attached to a rope with a plastic fishing float or a rope with a plastic float or oil drum at the end.
