A good anchor is essential for a boat, and every boat should have at least one anchor. So, you should be careful while selecting an anchor for your boat. Here are some tips for choosing an anchor for your boat.
While choosing an anchor for your boat, you need to consider the bottom conditions (sand, mud, weed, grass, rocks, silt, clay, gravel). You can’t use a single type of anchor for all bottom types. One anchor will set well in sand, and another in rocks, etc. So, it depends on the bottom type as well.
So, while choosing an anchor, the type of the bottom you are anchoring in plays a major role. In the below table, I mentioned what type of anchors you need to use based on all bottom conditions.
| Bottom Type | Type of anchor that set well in that bottom | Examples |
| Sand bottom | Fluke, CQR, Delta, Bruce, Modern | Danforth, Fortress, Plough, Delta, Rocna, Mantus, Manson Supreme, Spade, Claw |
| Mud bottom | Fluke, CQR, Delta, Bruce, Modern | Danforth, Fortress, Rocna, Mantus, Manson Supreme, Spade Delta, Claw |
| Clay bottom | Fluke, CQR, Delta, Bruce, Modern | Danforth, Rocna, Mantus, Manson Supreme, Spade, Delta |
| Rocky bottom | Modern, CQR, Delta, Fisherman | Northill CQR, Rocna, Mantus, Manson Supreme, Spade, Delta, |
| Gravel or pebble bottom | Modern, CQR, Delta, Fisherman | Northill CQR, Rocna, Mantus, Manson Supreme, Spade, Delta, |
| Grass bottom | Modern, Delta, CQR | CQR, Rocna, Mantus, Manson Supreme, Spade, Delta |
| Weed bottom | Modern, Delta, CQR | Spade, Plough, Mantus, Manson Supreme |
| Silt bottom | Fluke, CQR, Delta, Bruce, Modern | Danforth or fortress, Plough, Delta, Rocna, Mantus, Manson Supreme, Spade, Claw |
Those are the different types of bottom conditions, and you need to use the recommended type of anchors for particular bottoms. For some bottom types, all the types of anchors will set well. Now, we will see what size anchor you need to buy for your boat.
The size of the anchor you need to choose depends on the size, weight of your boat, and bottom conditions as well. First, you need to check the bottom conditions, then select the anchor type. After selecting the anchor type, then select the anchor size (weight) based on the boat length and weight.
For each type of boat, the anchor sizes will vary, and their boat recommendations will vary a lot. So, first, select the anchor type based on the bottom wherever you boat, and then select the anchor size.
For selecting that, first, we need to know the anchor types and which one is perfect for their particular bottoms. Now, we will see the major types of anchors that are available out there. After that, we will see the anchors based on the different bottom types.
Types of boat anchors
- Fluke or Danforth anchor
- CQR or Plow anchor
- Delta or Wings anchor
- Bruce or Claw anchor
- Modern anchors or New generation anchors
- Mushroom anchor
- Grapnel anchor
These are the basic types of anchors, and these are used majorly by the boaters. Now, we will see each type in detail. Before starting that, I wanna point out one essential point. If you are looking to buy an anchor for the first time, then you should be careful because there are many copies of original anchors available out there.
Copy anchors mean it is made up of a different type of material (other than the original type of material that is used to make that type of anchor) or made by a different company. Sometimes, if it is made by a different company, then they might change the name of the anchor. So, while buying an anchor, if it sounds different, it’s fine.
For example, take a fluke type anchor you can get maybe 10 or 20 copies of a fluke type anchor. So, if you are buying an anchor for the first time, you may not know whether it is an original anchor (good quality one) or, its a copy anchor (low quality one). If the copy anchor is made using a strong material, then it is fine to buy the copy anchor.
Sometimes, these copy anchors are made up of poor quality material. While buying an anchor for the first time, you need to be careful about the copy anchors and their names as well.
1. Fluke or Danforth anchor
Fluke or Danforth anchors are the most popular anchors. Many boaters will use these anchors in their boats. We will now see for which type of bottom types we will use these Danforth or fluke anchors.
Fluke or Danforth anchors are used in the bottoms like sand, mud, clay, and silt. In hard clay bottoms, Fluke or Danforth anchors won’t set as nicely as it sets in normal bottoms. Still, it is a good option for clay bottoms. Fluke anchors are not suitable for rock, gravel, weed, and grass bottoms.

Fluke or Danforth anchor (linked to Amazon). Check the price in amazon, and it is worth buying a fluke anchor for sand, mud, clay, and silt bottom.
| Fluke anchors | Setting ability (for 5 points) | Resetting ability (for 5 points) | Holding power (for 5 points) | Robust (for 5 points) |
| Mud | 4 | 3 | 5 | 4 |
| Sand | 4 | 3 | 5 | 5 |
| Grass | 1 | 1 | 2 | 1 |
| Weed | 1 | 1 | 2 | 1 |
| Rock | 1 | 1 | 1 | 1 |
| Gravel | 1 | 1 | 1 | 1 |
| Silt | 5 | 4 | 5 | 4 |
| Clay | 4 | 3 | 4 | 4 |
Due to its fluke design, it will penetrate well in the sand or mud. These anchors are very light in weight. The stock is hinged so the flukes can penetrate toward the bottom. For some designs, you can adjust the optimal angle depending on the bottom type.
These anchors penetrate well at the bottom. Once, if it sets well at the bottom, then it can develop high resistance. Its lightweight and compact flat design make it easy to retrieve and relatively easy to stow. There is another type of Danforth anchor.
The other type of Danforth anchor is Fortress anchor. The Fortress is an American aluminum alloy Danforth variant. It can be disassembled for storage, and it features an adjustable 32° and 45° shank/fluke angle to improve holding capability in bottoms such as hard sand and soft mud.
Danforth anchors reset well and the fortress anchor will not reset like a Danforth anchor. A Danforth will not usually penetrate or hold in gravel or weed or rock bottoms. In the below table, I listed the Fluke or Danforth anchor size based on the boat size (source). The values may vary a little bit if the boat weight is heavy or very light.
| Anchor Weight (in lbs.) | Boat Length (in feet) | Holding Power (in lbs.) |
| 3.5 lbs. | < 10 feet | 160 lbs. |
| 5 lbs. | 10-17 feet | 300 lbs. |
| 9 lbs. | 17-27 feet | 600 lbs. |
| 14 lbs. | 27-31 feet | 920 lbs. |
| 16 lbs. | 31-36 feet | 1300 lbs. |
| 25 lbs. | 36-40 feet | 1600 lbs. |
| 43 lbs. | 40-45 feet | 2000 lbs. |
| 70 lbs. | 45-55 feet | 3000 lbs. |
| 100 lbs. | 55-60 | 3500 lbs. |
The advantages of Fluke or Danforth anchor and Fortress anchor
- Fluke anchors are excellent in normal sand, silt, mud, and clay bottom types.
- Fluke anchors are very light in weight.
- Fluke anchors can be stowed well in the boat.
- Fluke anchors can be disassemblable.
- Fluke anchors are inexpensive compared to other style anchors.
- Fluke anchors will be the right choice for small boats because fluke anchors are lightweight type anchors.
The disadvantages of Fluke or Danforth anchor and Fortress anchor
- Fluke anchors are not suitable for rock, gravel, weed, and grass bottom types.
- Fluke anchors have less holding power than other anchors.
- Fluke anchors will not reset easily if the wind or current shifts.
- Fluke anchors are not the right choice for big boats because these are lightweight anchors and may not work well for big boats.
- The anchor flukes might bend if you use fluke anchor in rock or gravel bottoms.
2. CQR or Plow anchor
CQR or Plow anchors are also known as hinged anchors, and one of the good ones for anchoring. Many big boaters will use these anchors in their boats. We will now see for which type of bottom types we will use these CQR or Plow anchors.
CQR or Plow anchors are used in the bottoms like rock, gravel, sand, grass, clay, weed, mud, and silt. But in grass, weed, and very soft bottoms, CQR anchors won’t set as nicely as it sets in normal bottoms. Still, CQR anchors are okay for grass, weed, and very soft bottom types.

CQR or plow anchors (linked to Amazon). Check the price in amazon, and it is worth buying a CQR or plow anchor for rock, gravel, clay, sand, mud, grass, weed, and silt bottom (sometimes, may not work well in grass, weed, and very soft bottoms). But, the problem with CQR anchors is the hinge, the anchor may roll sideways if the wind or current changes. Consider that point while buying a delta anchor.
| CQR anchors | Setting ability (for 5 points) | Resetting ability (for 5 points) | Holding power (for 5 points) | Robustness (for 5 points) |
| Mud | 4 | 3 | 5 | 4 |
| Sand | 4 | 3 | 5 | 5 |

CQR or Plow anchors can be stowed conveniently in a roller at the bow, and have been popular with cruising sailors and private boaters. CQR or Plow anchors are generally good in all types of bottoms, except soft bottoms.
The only problem with CQR or Plow anchors is that it won’t set properly. Generally, it takes time to set due to the hinge. And another problem with CQR or Plow anchors is it will roll down if the wind or current changes. So, it might be an issue for many boaters.
This anchor is a big one, and due to its hinged design, it is more difficult to stow it in the boat than the Fluke anchor. This is why most people purchase the Fluke anchor over the Plow anchor as long as the Fluke anchor will meet all their needs.
You need to consider those things while buying a CQR or Plow type anchors. To prevent those problems, they invented non-hinged types of anchors known as Delta or Wing anchors. Many modern anchors are also designed similarly to a Plow style anchor. Some of them are Rocna, Manson Supreme, Mantus, Spade anchors.
There are different brands available out there, and you can’t find all types of sizes in only one brand. In the below table, I listed the CQR or Plow anchor size based on the boat size (source). The values may vary a little bit if the boat weight is heavy or very light.

- CQR anchors will be the right choice for big boats because these anchors are heavy anchors.
The disadvantages of CQR or Plow anchor
- Sometimes, CQR anchors will not set properly or holds less in the grass, weed, and very soft bottoms.
- CQR anchors roll over to the side easily than other anchors.
- CQR anchors take more space, and can’t be stowed easily in the boat due to its hinge design.
- CQR anchors take time to set at the bottom.
3. Delta or Wing anchor or Non-hinged anchor
Delta or Wing anchors are also known as non-hinged anchors, and one of the good anchors. Delta or Wing anchors are many ways similar to CQR or Plow anchors. We will now see for which type of bottom types we will use the Delta or Wing anchors.
The Delta or Wing anchors are used in the bottoms like rock, gravel, grass, clay, sand, mud, weed, and silt. But in the grass, weed, and very soft bottoms, Delta or Wing anchors won’t set as nicely as it sets in normal bottoms. Still, they are okay for weed, grass, and very soft bottom types.
“Delta anchor is almost the same as CQR anchor (performance-wise).”

Bruce or Claw type anchors won’t set quickly in most of the bottoms, but they have the strong ability of not breaking out with tide or wind changes, instead slowly turning in the bottom to align with the force. Sometimes, these anchors may roll down and hold with only one the claw, rather than three claws.
That is the main drawback of Bruce or Claw anchors. These anchors won’t penetrate easily in grass and weed. Bruce or Claw anchors are not good for grass or weed bottoms. Bruce or Claw anchors set well in the low scope. Bruce or Claw anchors are more effective in large sizes than smaller ones.
In the below table, I listed the Bruce or Claw anchor sizes based on the boat size (source). The values may vary a little bit if the boat is heavy or very light.

For sand, mud, silt, and clay bottoms, Fluke anchors are excellent. But, if you have a big boat, then don’t buy fluke anchors (for big boats fluke anchors are not okay, you need big anchors such as modern, cqr, delta, and bruce). But, for those bottoms (sand, mud, silt, and clay), all boat anchors will work well. So, it depends on your budget (if you have a reasonable or good budget, then go for bigger ones).
For rock, gravel, grass, and weed bottoms, modern anchors are excellent. Still, CQR and delta anchors are excellent. But when it comes to modern VS other anchors, definitely modern anchors will win because they are designed like that (robust). Even fisherman anchors like Northill will work well for those bottoms. Bruce anchors may not work well in those bottoms.
