Holding power is formulated based on environmental factors, like wind speed. As a general rule, a holding power of 90 pounds is sufficient for safely anchoring a 20′ boat in winds up to 20 mph. For the same wind speed a holding power of 125 pounds is adequate for a 25′ boat.
Generally if you have a boat 22′ or less, you have several options, since you aren’t likely to be out in 25-30 mph winds in that size boat – so our 7 lb, 10 lb, or 14 lb could be chosen for boats 22′ or less. But it is recommended that you carry the largest anchor you can feasibly fit on your boat.
How do I choose a boat anchor?
Boaters frequently ask us what the best type of anchor is for their boat and the answer is often “more than one anchor, of different types.” The type of bottom—mud, grass, sand or rock—will dictate different choices of anchors, as will the size and windage of the boat, the wind conditions and the sea state.
What type of anchor is used for small boats?
Danforth or Fluke Anchor
This style of anchor is a good choice for smaller boats because it folds flat and is easy to stow, and has great holding power for its weight. Its wide, sharp flukes sink into sand and hard-mud bottoms, but are less effective in deep mud or a grassy bottom.

It is also referred to as a Danforth anchor or a Lightweight anchor. Fluke anchors have high holding abilities attributed to their wide and flat flukes, commonly made from strong steel.
Do ship anchors touch the ocean floor?
Does a boat anchor have to touch the bottom? Yes, all anchors rest on the seabed. An anchor is designed in such a way that it digs into the seabed and holds the boat from moving away. An anchor works together with a chain.
How long should your anchor line be?
A good rule of thumb is that the length of the line should be at least seven to ten times the depth of the water where you are setting anchor.
Can an anchor sink a ship?

Do you drop anchor in a storm?
If the storm rises when the ship is in a harbor, an anchor is dropped from the bow (front) to secure it to solid ground below. The anchor keeps the bow pointed into the wind as the ship safely pivots around it, preventing the ship from capsizing.
What happens if a ship’s anchor gets stuck?
If the anchor becomes stuck, pulling on the trip line can reverse the anchor out of its position since the line is attached to the head of the anchor instead of the shank. With trip lines, it is very important to account for the tides when determining how much slack to leave when attaching your buoy.
What happens when a ship loses its anchor?
Anchor and chain loss can often lead to collisions and grounding, which can result in additional damage to a vessel. Adding to the costs of anchor loss is the increasingly common requirement from port authorities that lost anchors are recovered.
