5 key benefits of using a snubber and how to install it on a charter boat

Improve your mooring with a gadget that every professional sailor uses.

Are you confident when it comes to anchoring your boat? In popular sailing destinations like Greece, anchoring is often a necessity due to limited marina space. But there’s no need to feel apprehensive — as long as you follow proper procedures and safety protocols, anchoring can be simple and straightforward. Experienced sailors know that anchoring cannot be done without the use of a snubber. So, if you’re not using one yet, here are five reasons that might convince you to start.

1. More comfort at anchor

A snubber greatly enhances comfort while anchored by absorbing the shocks caused by wind and waves. Without a snubber, the boat can experience sudden, jerky movements as the anchor chain tightens. The elasticity of the snubber acts as a shock absorber, distributing the impact of these external forces more evenly, reducing strain, and making your time at anchor far more pleasant.

2. Protecting the anchor windlass

Your anchor windlass is a crucial piece of equipment that you want to keep in good working condition, especially on charter boats where wear and tear are unknown. When the full weight of the boat rests on the windlass — particularly in rough weather — it can easily become overloaded. A snubber helps by transferring the load from the windlass to the boat’s cleats, which are designed to handle high stress. This reduces strain on the windlass, extends its lifespan, and lowers the risk of accidental chain release or motor failure.

3. Anchor chain protection

A snubber not only protects the windlass but also relieves the anchor chain by reducing direct strain. This extends the chain's lifespan and minimizes the risk of damage or breakage, especially in challenging conditions. By absorbing the load that would otherwise be placed on the chain, the snubber prevents wear and tear, ensuring your anchor system remains reliable and secure, even in rough weather.

4. Peace and quiet on board

One often overlooked advantage of using a snubber is the significant reduction in noise. Without it, the anchor chain can create loud, unpleasant sounds as it grates or rubs against the boat or seabed, especially in windy conditions. This can be particularly disturbing at night when you’re trying to sleep or relax. A snubber dampens these noises by absorbing the tension in the chain, contributing to a much calmer and quieter atmosphere on board.

5. Show off your expertise

Using a snubber is a clear sign of an experienced and responsible sailor. It shows that you take mooring seriously and that you understand the importance of properly securing your boat. Fellow boaters will notice your professionalism, and you’ll gain confidence, knowing you’ve taken the right steps for a safe and efficient anchoring setup.

How to use a snubber on a charter boat

Using a snubber on a charter boat is simple, even without a dedicated chain hook. Follow these tips for easy setup:

Bring your own chain hook

Charter boats typically don’t come with a chain hook, so it’s a good idea to bring your own. Ensure that it fits the chain size, which is usually 8 mm or 10 mm on charter boats. A chain hook makes attaching the snubber both the easiest and most secure option.

Do you have a chain hook? Try a shackle or carabiner

If you don’t have a chain hook, you can use a shackle or a carabiner. Be cautious with carabiners, as they can twist under load, making them difficult to remove. A shackle tends to be more reliable. If neither option is available, using the right knot can be just as effective.

Consider the good old rolling hitch knot

A tried-and-true method for attaching the snubber is the rolling hitch knot. This knot securely grips the anchor chain and won’t slip, even under heavy load. Learning to tie this knot is a valuable skill that ensures a secure connection and peace of mind while anchored.

Choosing the right rope for snubber

The snubber rope should be at least 5 metres long and made from flexible, non-floating material such as nylon, which has the elasticity needed to absorb shock. The rope’s thickness should be based on the weight of your boat. For instance, an 8 mm rope is generally sufficient for boats weighing up to 4.5 tonnes under normal conditions.

While any snubber is better than none, selecting the right one can significantly improve safety and comfort at anchor. Even if a snubber fails, the mooring system will continue to hold the boat, though not as efficiently.

Installing a snubber on a sailboat step-by-step

Once you’ve found a suitable bay and successfully anchored, follow these steps to properly install a snubber.

Step 1: Attach the snubber to the anchor chain

A) If you have a chain hook: Tie the chain hook to the centre of the snubber rope using a double fisherman’s knot, ensuring the hook is securely attached. This allows you to easily clip the hook onto the anchor chain.

B) If you don’t have a chain hook: Use a rolling hitch knot to tie the centre of the snubber rope directly to the anchor chain. If the chain passes through the bow roller, you can tie the snubber at the anchor gate. Alternatively, if necessary, you may need to lean over the bow and tie the knot onto the hanging chain.

Step 2: Secure the snubber to the cleats

Run both ends of the snubber rope outside the boat and secure them to the cleats where you usually tie the mooring lines. Ensure that the total length of the snubber, from one cleat, through the anchor chain, to the other cleat, is at least 5 metres.

Step 3: Lower the anchor chain

Release enough of the anchor chain so that it sags by at least one meter below the snubber, under the water. This allows the snubber to take over the load, reducing stress on the mooring gate and the anchor chain. It prevents the chain from pulling directly on the boat and helps absorb shock from waves and wind.

Snubber, a.k.a. Bridle on catamarans

On catamarans, a snubber — or more accurately, a "bridle" — is even more essential and is usually pre-installed on charter boats. The bridle consists of two ropes, one attached to each hull, making it crucial for distributing the load evenly between them.

This setup is vital because of the unique way catamarans behave when anchored. Due to their size and design, catamarans tend to swing more in the wind compared to monohulls. The bridle helps to stabilize the boat by spreading the load across both hulls, preventing uneven strain and protecting the anchor chain from rubbing against the hull.

Incorporating a snubber or bridle into your anchoring routine ensures a safer and more comfortable experience, regardless of weather conditions. Next time you’re at anchor, look around — you’ll notice that seasoned sailors always rely on these tools for smooth, secure mooring.
