Udover at forankre skibet sikkert ved ankerpladsen, kan ankeret på fiskerbåden i aluminium også udføre følgende funktioner:
1. Nødbremsning
Ankeret bruges til at begrænse skibets fremadgående trækkraft. Ofte når køretøjet køres baglæns, suppleres det med at kaste det første anker for at få skibet til at stoppe fremrykningen i en nødsituation.
2. Styr vandret bevægelse
Når skibet nærmer sig kajen, bruges det ofte til at smide ankeret for at kontrollere Yuepengbai for at bevæge sig sideværts til kajen, og kaste ankeret ned for at kontrollere fremadgående hastighed.
3. Hjælp dig med at-vende
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. Undertrykk afbøjning
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. Hjælp med at komme af krogen
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.
