because the water pressure takes up some of the weight as you lift it in the water
Because there is more buoyant force acting in it and because there's more pressure inside the water. When you lift it into the boat it is harder because the water is pulling it down.
The weight of an anchor is not as important as the type and design of the anchor used. Finding the appropriate anchor will also depend on the type of boat and the composition of the bottom of the body of water it is to be used in. In addition, lighter anchors are (obviously) easier for the boater to handle. Check with local boat shops or experienced boaters to find the right anchor.
Sailing yachts have the anchor at the bow of the boat.
The volume of the displaced water would be less - as you're reducing the mass of the boat. Another viewpoint: I think there's a bit more to this question, but the basic answer remains the same. I think it's all about "Archimedes' Principle". Let's consider the anchor as still part of the boat. Also let's think about it before it gets partly buried in the ground underwater. Archimedes' Principle tells us: The "upthrust" on the boat before the anchor is lowered is equal to the weight of the whole boat. That equals the weight of water displaced. The anchor itself doesn't float in water. It is denser than water. When the anchor is completely submerged it displaces an amount of water equal to the anchor's volume (not the anchor's weight). When the anchor was on the boat it displaced an amount of water equal to its weight. So, when the anchor is lowered, the boat (including anchor) displaces a slightly smaller volume of water.
Move the boat directly over the anchor
A rapidly ringing bell every minute signals a vessel at anchor.
To remove an anchor from a boat effectively and safely, follow these steps: Ensure the boat is securely anchored and not drifting. Put on gloves to protect your hands. Use a winch or windlass to slowly raise the anchor. Keep the anchor chain or rope taut as you lift the anchor. Once the anchor is clear of the water, secure it on the boat to prevent it from swinging. Rinse off any mud or debris from the anchor before stowing it away. By following these steps, you can safely and effectively remove an anchor from a boat.
To calculate the depth a boat is submerged in water, you can use Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the water displaced. By comparing the weight of the boat to the weight of the water displaced, you can determine the depth the boat is submerged. This can be calculated using the formula: Depth submerged = (Weight of the boat) / (Density of water * g), where g is the acceleration due to gravity.
No, an anchor does not have to touch the bottom in order to secure a boat in place. The anchor's design and weight help it grip the seabed and hold the boat in place.
