Anchors are one of the most important pieces of equipment on any vessel, whether you are an experienced sailor or a beginner in the world of boating. The proper selection, use, and maintenance of an anchor have a direct impact on the safety and stability during a voyage.
In this guide, you will find a comprehensive overview of anchor types, tips for choosing the right anchor, recommendations regarding weight and size, practical anchoring advice, and a review of the latest innovations in anchors.
Types of Anchors and Their Characteristics
Choosing the right anchor depends on the type of vessel, water conditions, and seabed characteristics. The most common types of anchors are:
- Bruce (claw) anchor:Suitable for sand, gravel, mud, silt, and pebbles; holds well on rocky bottoms but less so in grass. Its shape allows it to quickly “grab” the seabed and is popular among many boaters.
- Danforth (fluke) anchor:Very widespread, excellent holding power on sandy and muddy bottoms as well as grass, but less effective in silt or rocky terrain.
- Delta anchor:Features a low center of gravity and fast penetration into the seabed. Suitable for sand, gravel, and rocks, it holds well even in challenging conditions. Its geometry allows it to hold the vessel’s force at a single point.
- Ultra Anchor:An innovative stainless steel anchor with unique features such as a hollow shank, lead tip for optimal weight distribution, special shape for rapid penetration, and high corrosion resistance. Suitable for all seabed types and provides exceptional reliability.
- Admiralty, CQR, Spade, Rocna, Mantus:Each of these anchors has its own specific features and is suitable for certain conditions or vessel types.
Practical tip: Always choose an anchor best suited to the predominant seabed in your sailing area. If you frequently anchor on different terrains, consider having multiple anchors or a versatile model like the Ultra Anchor.
Correct Weight and Size Selection for Anchors
Anchor weight and size are key factors for effective anchoring. A general rule of thumb is that the anchor should be heavy enough to hold your vessel in all conditions, often recommended at about 1 kilogram of anchor weight per 4 meters of vessel length. However, other factors such as the vessel’s total weight, weather conditions, length and thickness of the chain, and especially the type of seabed where you most frequently anchor must be considered.
Smaller vessels often require lighter anchors, while larger and heavier vessels need more robust and heavier anchors. If you often sail in demanding conditions such as strong wind or current, or on poor seabeds, it is advisable to choose a slightly heavier anchor than what your vessel length alone would suggest. An anchor that is too light may slip and fail to provide security, while one that is too heavy can be cumbersome to handle, so finding the right balance is important.
Always consider the recommendations of your vessel and anchor manufacturer, as well as the experience of other sailors navigating similar conditions.
How to Choose the Right Anchor for Your Vessel
When selecting an anchor, consider the following factors:
- Vessel length and weight:The bigger and heavier the vessel, the larger and heavier the anchor needed.
- Seabed type:Sand, mud, rocks, or grass – different anchors perform better on different seabeds.
- Type of boating:If you frequently anchor on various seabeds, choose a universal anchor or combine several anchors.
- Anchor material:Stainless steel is most corrosion-resistant, galvanized steel is more affordable, aluminum anchors are lightweight and suitable for auxiliary vessels.
- Modern innovations:Ultra Anchor and similar innovations offer better stability, faster penetration, and easier handling.
Practical example: For a 9-meter boat mostly anchoring on sandy seabeds, a 10 kg Delta anchor is an excellent choice. For greater versatility, consider an Ultra Anchor or Bruce anchor.
Proper Use and Anchoring Technique
Anchor effectiveness depends not only on its shape and weight but also on correct usage:
- Selecting the anchoring spot:Check water depth, seabed type, and distance from other vessels.
- Preparing the anchor:Ready the anchor at the bow, lower it into the water when the vessel is stopped with the wind ahead.
- Length of chain or rope:The general rule is that the chain length should be 3 to 4 times the water depth. A longer chain provides a better pull angle and greater reliability.
- Securing the chain:Once the anchor is on the seabed, secure the chain at the bow and check that the anchor has set.
- Raising the anchor:Raise the anchor gradually in 15-second intervals with pauses to avoid overloading the windlass.
- Freeing a stuck anchor:If the anchor gets stuck, try maneuvering or using an additional rope; never force the windlass.
According to practical data, over 60% of cases where anchors fail to hold are due to improper use or insufficient chain length, not poor anchor design.
Maintenance and Safety Recommendations
Regular maintenance of the anchor and related equipment is vital for safety:
- Check the condition of the anchor, chain, and rope: Look for signs of wear, corrosion, or damage.
- Clean the anchor regularly: Rinse with fresh water after each retrieval and remove any deposits.
- Inspect the windlass operation: Service the windlass regularly and check fuses and electrical connections.
- Store the anchor safely: When not in use, store it in the designated space and secure the cover.
Always carry a spare anchor on board, especially for longer voyages or in challenging conditions.
Innovations and Modern Solutions: Ultra Anchor and Accessories
Modern anchors such as the Ultra Anchor bring numerous innovations:
- Hollow shank and lead tip:Enable optimal weight distribution and fast penetration into the seabed.
- Special shape:Increases holding surface and provides exceptional stability even with changing pull directions.
- Material:Stainless steel 316L ensures long service life and corrosion resistance.
- Accessories:The Ultra Flip Swivel allows easy connection between the chain and anchor and prevents tangling.
Ultra Anchor is suitable for all vessel types and seabeds and is available in various sizes (from 5 to 360 kg). Manufacturers also offer a lifetime warranty against structural defects.
Anchor as Part of Mandatory Equipment on a Vessel
According to Slovenian law, every vessel must be equipped with a suitable anchor and anchor rope adapted to the vessel’s length and weight. For vessels up to 6 meters, a lighter anchor with rope is sufficient; for larger vessels, a chain and additional safety equipment are mandatory.

Make Your Anchoring Safe and Worry-Free
Choosing the right anchor, proper use, and regular maintenance are the foundation of safe and comfortable boating. Remember to:
- Adapt the anchor to your vessel type and predominant seabed.
- Use a sufficiently long chain or rope.
- Regularly inspect and maintain your anchor and related equipment.
- Consider modern innovations that can improve your safety and comfort.
