Sailing yachts have the anchor at the bow of the boat.

A rode roller sailboat anchor pulley is a part that can be replaced on a boat. Some people can find the part on sites such as ebay.
Move the boat directly over the anchor
It is recommended by the USCG that all vessels should be anchored from the bow,{front} and never the rear. In Texas it is illegal to anchor your boat in lakes or creeks and rivers from the rear.
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.
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.
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.
