THE ULTIMATE ANCHOR GUIDE: EVERYTHING YOU NEED TO KNOW
A stable anchor is the key to a worry-free mooring time on board. After all, when it comes to keeping your boat securely in place, choosing the right type of anchor is essential. In this comprehensive guide, you'll learn all about the different types of anchors and get helpful recommendations on how to choose so you can make the best decision for your boat.
We'll look at the advantages and disadvantages of the different types of anchors, as well as their stability in different soils. In addition, we will discuss important selection criteria, including boat type and weight, water conditions and anchor bottom, weather conditions and area of use, as well as personal preferences and experience.
Furthermore, we will give tips on anchor care and maintenance, as well as the most important accessories.
Flunk anchor:
The flunk anchor, also known as a "folding anchor" or "plate anchor", is characterised by its folding flukes, which bury themselves in the ground when submerged. It is particularly suitable for soft or muddy ground. Flunk anchors are lightweight, compact and easy to store, though they may not provide the same stability in hard or rocky soils.
Danforth anchor:
The Danforth anchor, also known as a "wing anchor", consists of two symmetrical flukes that provide a high level of support in sandy or muddy soils. This type of anchor is lightweight, stows well and is suitable for a wide range of boat types. However, it may be less effective in hard or rocky bottoms.
Sleeve anchor:
The sleeve anchor, also known as a "Bruce anchor" or "Plow anchor", has a curved shaft with a rotating sleeve. This type of anchor provides good holding power in a variety of soil conditions, including mud, sand and grass. Swivel anchors are robust and well suited to larger boats or yachts. However, they can be bulky and require appropriate storage space.


Ploughshare anchor:
The ploughshare anchor, also known as a "CQR anchor", is a popular type of anchor for boats and yachts. It has a curved shank with a forward-facing plough that digs well into the substrate. The ploughshare anchor provides good holding power in different types of ground and is particularly effective in hard or rocky ground. It is suitable for larger boats and yachts, but can be a little bulky due to its weight and shape.
Delta anchor:
The delta anchor is a modern type of anchor with a triangular shank and a weight-optimised design. Compared to the ploughshare anchor, delta anchors do without the joint between plough and shank. It offers good holding properties in most soil types and is characterised by its fast and reliable anchoring. Delta anchors are popular with many sailors and boat owners, especially for medium to large boats.
Anchor type | Stability in different soils | Handling and weight | Space requirements and storage options |
---|---|---|---|
Flunk anchor | Good in soft or muddy soils | Lightweight and handy | Takes up little space, easy to stow away |
Danforth anchor | Good grip in sandy or muddy soils | Lightweight and handy | Takes up little space, easy to stow away |
Sleeve anchor | Good holding power in various soil conditions | Easy handling, requires space for storage | Somewhat bulky due to its shape, requires sufficient space for storage |
Delta anchor | Good holding properties in most soil types | Easy to operate | Variable depending on size and boat type, requires adequate storage space |
Ploughshare anchor | Good on hard or rocky ground | Easy handling, requires space for storage | Somewhat bulky due to its shape, requires sufficient space for storage |
Folding anchor | Good holding power in soft or muddy ground | Very light and easy to stow away | Takes up very little space, easy to stow away |
Anchor buoys and markers
An anchor buoy is often used to mark the anchor location. It can be attached to the anchor itself or to the anchor line to make visible where the anchor is located. This facilitates orientation and prevents possible collisions with the anchor.
Markers such as floating buoys or flags can also be used to mark the anchor location. They serve as visual reference points and help other boats to recognise the anchor location and keep an appropriate distance.

Anchor winches and anchor rollers
An anchor winch is a mechanical device that assists in retrieving the anchor. It makes the job easier, especially with larger anchors or in situations with strong winds or currents. The windlass can be operated either manually or electrically.
Anchor rollers are used to guide the anchor smoothly during retrieval and deployment. They allow easy and controlled manoeuvring of the anchor, especially when hauling in on deck. Anchor rollers are available in different sizes and designs to suit the requirements of the boat and the anchor.

Cleaning and rust removal
- After use, the anchor should be thoroughly cleaned of mud, sand and other debris. This can be done with fresh water and a brush.
- If rust has formed, it should be carefully removed. Rust converters or special rust removers can be used for this purpose.
- After cleaning and rust removal, the anchor should be dried thoroughly to prevent corrosion.
Storage and protection against corrosion
- The anchor should be stored in a dry and well-ventilated place to avoid humidity and corrosion.
- It is advisable to treat the anchor with an anti-corrosion agent before storage. Special anchor paints or sprays can help protect the anchor from corrosion.
- If the anchor is not going to be used for a long time, it can be stowed in an anchor sleeve or an anchor locker for extra protection.
Checking the anchor chain and rope
- The anchor chain and rope should be checked regularly for wear, cracks and damage. If any damage is found, it should be repaired or replaced immediately to ensure safety.
- It is important to regularly check the connections between the anchor chain, anchor rope and boat to ensure they are properly secured and intact.
