Boat Side Fender

What is Boat Side Fender

A Boat Side Fender is the cushion or padding that stops boats or what it is bumping against from taking on damage from docks or other boats. Fenders absorb the shock of impact and decelerate the boat as it moves about. As a boat owner, you quickly learn that fenders are the solution to preventing harm to your boat, docks, or other boats.The fender size and type you use depend on the length and weight of the boat and mooring conditions. A rule of thumb for fender size is for every five feet of your boat's length; you need one fender at least one inch in diameter. For more details on the size and type, check out our chart.

Benefits of Boat Side Fender

Protection During Docking
Docking your vessel doesn't always go smoothly, which is why every boat needs fenders for docking maneuvers, and while docked. . Once docked, your fenders will do all the hard work keeping your boat securely moored and protected from the dock, however, protecting your hull surface from perpetual fender contact (scratches, scuffs) should not be over looked. While a fenders surface is generally soft, that material is more rigid than a soft fabric fender cover, and if you value the condition of your hull, a good soft, stylish cover is very important.

A Touch of Personality

Since fenders are mandatory equipment that get used, abused, become dirty and or tattered, consider adding fender covers to instantly clean them up. First impressions last, so instead of presenting dirty or boring white fenders hanging off the side of your boat, clean them up with fender covers. Fender covers allow you to instantly color coordinate your fenders to your boat’s accents, and or you can add custom embroidery for that extra level of detail and personal touch.

Prevents Squeaking

Fenders are notorious for squeaking during moments of compression between the hull and dock. Anyone who sleeps aboard understands that the frequent cyclical squeak can be quite annoying. Adding a soft fender cover will mitigate squeaks, which can be an invaluable benefit to you and or your guests.

Increases Lifespan

Nearly every exterior item on a boat is subjected and impacted by the suns U.V. rays, and covers are generally used as sacrificial protection to protect the greater good. While fenders generally have good UV resistance characteristics, it is considered good preventative maintenance to keep them covered, especially when they are stored full time in the sun, so when the critical need arises, you can feel confident that your fender is ready for action.

How Boat Side Fender Work

Whether inflated or soft foam, cylindrical, spherical or flat-fenders absorb the shock of vessels bumping into docks or other vessels. They insulate the boat from damage and decelerate it as it surges and rolls about. Boats that tie up to floating docks usually set fenders just above the waterline to maintain a buffer zone between dock and boat. Boats that raft together place the fenders at the point of contact—generally where the beam is the widest. Docking next to pilings presents a special challenge; the pilings tend to push the fenders aside, with damaging consequences. A solution is to use a fender board that spans the distance between pilings. With the fenders and board, a boat can ride reasonably comfortably against a wharf.

How to Hang Side Fenders On a Boat

Here are some options you can use to make sure your fenders are in a secure position, minimizing not only damage but reducing the stress level when docking or connecting with other boats.

Brackets

Brackets are a great way to secure your fender lines in place and are easy to adjust the heights of your bumpers should you need to change them up for docking or mooring quickly. Our Taylor Made Rail Lifeline Fender Bracket makes it easy to get the right fender height.

Clips

Fender clips mount to your boat's lifeline and keep your bumpers in place. They can also hold power cords or other boat accessories, keeping your deck free of clutter. Shop the Taylor Made Lifeline Fender Clip.

Locks

Boaters use fender locks to keep their bumpers secure. Fender locks are either fixed or adjustable, allowing for flexibility of the height you need in specific scenarios. It's important that whatever height you need, you can respond quickly to your docking or mooring situation to protect your boat from damage from the dock or other boats. Keep your fenders secure with the Taylor Made Fender Lock.

How to Choose Boat Side Fenders Based on Boat Size

Before we can say that we avoided unnecessary spending, you need to make sure that you are not buying too much fenders (increased costs) or too little (low protection). To ensure reliable protection of the yacht when maneuvering during mooring, one should rely on the ratio of the size of the vessel and the dimensions of the fenders. Empirically, the maritime community has determined the following options for selecting fenders by number, diameter and length.

Cylindrical inflatable fenders should cover ⅔ of the side that rises above the water. Spherical and pear-shaped fenders have an increased damping effect, so it is enough that they cover ½ of the freeboard.The maximum distance between side fenders is 2.5 m (the less the distance, the more reliability you get), but their minimum allowable number on each side is 3 units.The diameter of cylindrical fenders depends on the length of the boat: for every 1.2 meters of the length of the yacht, there must be at least 2.5 cm of fender diameter.

How to Choose Boat Side Fender

The Size

The size of the boat fender per unit is calculated based on berthing energy, as this is the main session where the boat will receive bumps the most. But we have an instant way to measure the right boat fender's size for your boat. You need to remember the 1:5 rule. Then get to know and measure the diameter of the fender. The 1:5 rule means every 1 inch of fender diameter can be good for every 5 feet of boat length. The larger boat will need more cushion or boat fenders to protect them. Also, remember that the 1:5 rule is the minimum that you can apply for your boat, you will not have any problem providing bigger and more fenders, but this rule has run pretty well to be set as the minimum.

The Shape

There are two types of boat fender shapes. You might need the G-style one or A-style one. Now comes the question of what the difference is between those two shapes? G-shaped boat fenders might be the most common fender you could see. It fits most of the boat and is easy to get. Now, there is also an A-shaped boat fender. This boat fender is usually used in special conditions and is expected in fishing. It's good to protect the boat areas far from the dock, for example, the stern or bow, as this fender provides the maximum distance away from the dock. The A-shaped boat fender will effectively cover the sensitive area and give maximum protection to your boat against any bumps and hard rough surfaces.

Mooring Conditions

Colliding when docking is unfortunately a collision that you can't avoid - but that's why your fenders are there, to cushion the impact. When choosing the right fenders to suit your boat, you should consider the mooring conditions that you'll regularly be docking in. Are you going to be moored against a fixed object? Or another floating vessel? Without the right fendering application, the hull of your boat will quickly become damaged and you'll be left with further repair costs - as well as time out of the water.

Aesthetics

For tug boats (designed to withstand frequent impact and heavier collisions), the aesthetics of your fendering isn't usually the main concern. Whereas, for leisure yacht or holiday boat owners, you're not going to want to put ugly fendering on a nice looking boat, are you? So, depending on what type of boat you own, you should consider the aesthetics of your fendering.

Components of Boat Side Fender

Boat Fender Covers

Boat fenders need protection! And when you use covers for your boat bumpers, you are extending their shelf-life and can count on your fenders for many boating seasons. You don't have to worry about these covers marring or scratching your boat's gelcoat.

Fender Lines

Your fenders need dock lines so you can hang them from your boat. You will want to ensure that these fender lines are easy to use and won't kink when you're threading them through the bump

How to Prevent Boat Fender Fouling and Buildup in the First Place

Keep your fenders out of the water as much as possible
Most of the dirt and grime that accumulates on your fender is a direct result of being left in the water. Dirt, water, and salt begin to build up on the fender leading to unwanted stains and growth. Reduce this growth by keeping your fenders out of the water when not in use.

Spray and scrub your fenders regularly to reduce stains and build up
Stay on top of stains and unwanted sediment build ups by giving them a quick spray and scrub after each use.

Dry your fenders before returning them to storage
After scrubbing your fenders, be sure to dry them completely before returning them to their storage bins. This keeps them sparkling clean for the next time you need them and also mitigates the risk of mildew growth while in storage.

Common Mistakes to Avoid When Using Marine Boat Fenders

1. Choosing The Wrong Number Of Fenders

Figuring out the correct number of fenders is crucial for optimal protection, and, when it comes to this, both having too few or too many fenders might cause serious problems. Insufficient fenders can leave vulnerable areas of your yacht exposed to potential damage, while excessive fenders can clutter the docking area and impede maneuverability and speed – you don't want to turn your yacht into a huge clumsy inflatable dinghy. To determine the perfect number, consider the size, weight distribution, and vulnerable sections of your boat – one fender for every 2.5 meters of the side's length is a good rule of thumb.

2. Incorrect Fender Placement

Improper placement is a mistake that can completely negate all the usefulness of even the most expensive protective device. Correct fender placement involves identifying the areas of your boat that are most susceptible to impact during docking or passing through a lock – it is usually the widest beam points, where maximum protection is needed. For some reason it is not rare to see a boat without any such protection in various marinas!

3. Wrong Fender Height

Neglecting to adjust the height of the fenders as the water level changes during high and low tides can also render them quite useless: when positioned too high or too low they fail to provide adequate cushioning, since the impact area changes place. That's why it is important to adjust the fender height to match the changing water level based on local tide charts, that are a must have for every skipper.

4. Neglecting Timely Fender Maintenance

Let's not forget about the importance of proper servicing - neglecting it might lead to premature rupturing, decreased performance, and overall compromised protection for your vessel. You don't want a broken valve or to see your fender burst in a dangerous mooring situation – imagine that happening when going through chores like fender inspection, cleaning, and inflation checks – always works for us.

FAQ

Q: Where do I attach my fenders?

A: This is a critical question, as the placement of your fenders will determine how effectively your boat will be protected. Normally, the fenders will be attached to the railings and handrails, or they will be clamped down. Of course, fenders should be hung anywhere that there is a possibility of scratching or damage to occur. In most cases, fenders will be situated on top of the railing. If your fenders will be exposed to heavy forces or loads, we recommend that you secure the fenders with a clamp, a winch or a foot rail. The positioning of the fender is also critical because if it is wrongly placed, it can rub against the gelcoat and cause abrasions and damage. This applies to fenders, which have been hung either too high or too long on the hull. In these cases, the fender also does not offer optimum protection. So always try and find the perfect spot! TIP: We recommend using a single line spliced into each fender. This allows for individual placement and height adjustments to position your fenders into the perfect spots.

Q: How do I attach my fenders?

A: When attaching your boat fender, we recommend hanging your fenders with their valves facing downwards. Very rarely, a fender can burst. In this case, the valve of a burst fender can act like a bullet. With it pointing downwards, the valve will be shot down in to the water and not towards anyone on deck.
We recommend that you tie on your fenders using a clove hitch with a slip knot. This is the most widely used knot in Germany and it is taught as a part of all boating licence examinations in Germany. However, there are still some differentiating opinions in Germany among sailors concerning whether the clove hitch with slip knot, opposed to just the simple clove hitch is better for tying on fenders. As fenders are deployed quite frequently, the addition of using slip knots will speed up these processes, especially if your vessel is outfitted with multiple fenders. The main argument supporting the use of the simple clove hitch is that it is a more durable knot, which will remain in place even under great stress or loads. One other commonly used method is the use of a clove hitch along with two other half hitches for longer deployments and improved protection against the chaffing of fender lines. We won’t try to resolve these differentiating schools of thought here, but we do carry a selection of fender hooks, which can also be used to make the process of fender deployment much quicker and easier!

Q: Which colour for my boat fender?

A: Luhang offers customers a variety of boat fenders in many different colors. Of course the selection of fender colors is mainly an issue of personal preference, but they also fulfil other purposes. For example, if you use your fender as a buoy for an anchor, a specialty color can distinguish it from others around it. Generally, the lighter the color of the fender, the more bound it is to getting dirty, while dark fenders pair together very nicely with dark colored hulls. While deciding which color of fender you would like, you could also leave it up to your personal tastes and preference.

Q: How do I clean my boat fenders?

A: After the season is over, you really notice the punishment that you put your fenders through! Whether yours are marked up with abrasions caused by contact against rusty sheet piling or a dirty neighboring yacht, your fenders will need thorough cleaning. That means - don’t wait until the winter is over to clean your fenders. Instead, maintain the cleanliness of your fenders during the boating season or before you put it in to storage for the winter. It is important to note that we offer a wide range of cleaning products directed towards the upkeep of your fenders. It is necessary to only work with these products while wearing gloves. You should avoid all hand and eye contact with these products. In order to clean very dirty fenders, we recommend using water and soap initially before using

Q: What is a boat fender and when is it used?

A: A boat fender is an inflatable protective body that prevents scratches and other damage to the hull of a boat while manoeuvring through the marina and when moored to the sheet piling or during boat to boat contact. Fenders are available in different sizes and shapes depending on the size of the boat.

Q: How many fenders should I have on board?

A: You can never have enough fenders on board. But as space is limited on any boat, the question becomes more critical - do I have the right number of fenders on board? For boats up to 10 meters in length, a general rule of thumb is to have two fenders for each side, with one or two replacement fenders at your disposal. On boats over 10 meters, you will be best served by having 3-4 fenders per side, with one or two replacement fenders as well. The side fenders should be in place for docking, but you may find yourself needing the spare fenders to help offset a rolling swell or strong breeze pinning you to the dock or sea wall. Here too, having more than one shape or type of fender will come in handy during many situations.

Q: Which boat fender for which boat? The various types of fenders

A: As previously described, the issue of limited storage space on one hand, and the high need for protection on the other hand, creates a tough compromise regarding your choice of fenders. This issue can however, be mitigated through the proper selection of fenders. The standard types of fenders are the typical ball and long fenders. You should pay close attention to the fact that you should buy fenders, which are the same size and design because you need to distribute pressure equally amongst your fenders, as mixing sizes can place unequal pressure on your equipment. The size of the fenders should be based primarily on the length and weight of the boat, as well as the height of the hull above water. The greater the size of the boat, the more affect wind and waves will have against its hull, meaning more protection will need to be given to the hull. A high freeboard can call for a much larger fender than a boat of similar weight and length, but with a low freeboard.

Q: What are the different types of boat fenders?

A: Designs include D type, cone type, drum type, fan-shaped, rectangular, and cylindrical. Solid rubber fenders have high energy absorption and reaction force, are low cost, have a long service life, and are easy to install and maintain. In addition to their use on vessels, they are often found protecting docks as well.

Q: What is the importance of marine fenders?

A: Fender systems prevent damage to both ships and dock structures. They minimize the direct friction between the hull of the vessel and the concrete or wooden structure of the quay, which would result in damage to both structures.

Q: What are boat fenders made of?

A: Rubber, foam elastomer and plastic are the most popular materials that boat fenders are made out of.Fender covers are designed to protect the hull of the boat while it is docked. Often forgotten, fender covers save your boat from scratching and extend fenders lives that are constantly exposed to a high volumes of UV and friction.

Q: What is the purpose of the fender system?

A: A fender system's main function is to ensure the safe berthing of a vessel and protection of port infrastructure. It must be able to absorb the kinetic energy of all specified vessels under all possible site environmental conditions, in order to prevent structural or vessel damage.

Q: Do boat fenders need to be inflated?

A: They come in a variety of sizes to accommodate a full range of watercraft. While they do require you to do the inflating on your own, you should only need something as simple as a manual bike tire pump to get the air flowing. If you're a casual boater on a factory-standard craft, inflatable fenders are a smart choice.
