Before going to sea, in addition to ensuring that your favorite boat has all the systems and equipment installed in accordance with your needs, there is one more thing to ensure that it operates as usual, and that is the process of anchoring, which is very important to ensure the safety of you and your boat. As the saying goes, "Anchor of a big ship-be steady", it is also a boat. The anchoring of yachts and sailboats is also a technical job. Let us take a look at the steps of anchoring.
First of all, you must know how long you are going to lay down the chain. Normally, you should be equipped with an electronic measuring instrument to measure the length of the anchor required. If this device is not available, then the anchor chain must be painted and marked, with a mark every ten meters. Now suppose you are driving a yacht or sailing boat into a peaceful bay, ready to drop anchor.
1) Remember not to anchor in the wind, because the wind will blow the boat away. Should choose typhoon shelters leeward.
2) Observe the surrounding environment carefully. The surrounding ships that have dropped anchors determine whether you can choose this underground anchor. Make sure there is enough space around your boat. Because the wind may move the ship, if you get too close to other anchored ships, there is a danger of collision.
3) The location of anchoring depends on the depth of the water. It should neither be too deep nor too shallow. 6 meters is ideal. Because it is too shallow, if the anchor needs to be lifted in an emergency, the time is too short to respond. If it is too deep, it is more difficult to prepare a long enough anchor chain. Therefore 20 meters is the upper limit.
4) Make sure you understand the seabed of this place before anchoring. You can get this information from the chart. If it is sand, no problem! If it is rock or coral, then a thin wire should be installed on the anchor head to facilitate the anchoring, so as to prevent the anchor head from getting stuck in the rock.
5) Stop the ship at the place where you are going to anchor, first use a windlass to hoist the anchor tightly to prevent it from swaying and hurting the hull.
6) Then quickly put down the anchor (note that no children are around during the operation). When it hits the bottom, you can feel the speed slow down. At this time, lock the anchor and check the length of the anchor chain to make sure it is consistent with the depth of the water.
7) Then, use the remote control to slowly lower the anchor chain to at least three times the depth of the water (if the situation is complicated, increase the coefficient to 5 to 7 times). The speed should be slow, consistent with the speed of the boat moving in the breeze. The purpose is to avoid piles of anchor chains on the anchors, but to distribute them evenly within the drift range of the ship.
8) When determining the ideal length, for example, a 20-meter anchor chain at a depth of 6 meters (measured by electronic records or the mark on the chain), a movable nylon rope (it can be the kind used for berthing) Cable material). It should be 22 mm in diameter and 6 meters long. There should be a hook on one end that can be hooked to the anchor chain, and the other end to the horn of the bow. This function is equivalent to a shock absorber, which can reduce the tensile load of the anchor chain on the windlass. Of course, if your boat is equipped with an anchor chain lock configuration, you can use this equipment directly.
9) The engine is idling slowly, so that the ship is slowly pulled back to straighten the anchor chain, so that the anchor will sink into the sand, the load reduction device will work, and the windlass will no longer bear the weight.
10) When the engine is idling until the ship stops, increase the RPM to drop the anchor deeper. After that, take the two fixed points on the shore at a 90-degree angle to the ship, and visually judge whether the ship stands still? If one of these two points is still moving, it means that the ship is still towing, which means that the anchor is not stable. Then choose another place to anchor, or stay on the boat at all times to be vigilant to ensure that you can react quickly when the wind speed increases.
11) If the boat does not move, turn off the engine. Congratulations, you have successfully dropped the anchor!
