Sidro ribiškega čolna iz aluminijeve zlitine lahko poleg varnega zasidranja ladje na sidrišču opravlja tudi naslednje funkcije:
1. Zaviranje v sili
Sidro se uporablja za omejevanje potiska ladje naprej. Pogosto, ko se vozilo pelje nazaj, se to dopolni s spustitvijo prvega sidra, da se ladja v sili ustavi napredovanje.
2. Nadzorujte vodoravno gibanje
Ko se ladja približa doku, se pogosto uporablja za odvrženje sidra za nadzor Yuepengbaija, da se premakne bočno do doka, in vrže sidro navzdol za nadzor hitrosti naprej.
3. Pomagajte -obrniti
U-turn in narrow waters, such as the depth of water and the bottom quality of the river bed suitable for anchoring, often can be used to lead the operation method of anchoring to make the ship turn around smoothly.
4. Preprečite odklon
When the ship needs to retreat for a long distance, in order to ensure that the ship can move in a straight line, the bottom quality of the river bed allows it. The anchor chain can be dropped to the end and the anchor chain can be stopped to form a towing anchor and achieve the purpose of restraining the deflection of the ship's breast.
5. Pomagajte, da se znebite
After the ship ran aground, a small boat can often be used to transport the anchor to a distance (upwind, current direction) and drop it, and then twist the anchor rope to make the ship go shallow.
