If you are a boat owner, you’re probably painfully aware of all the hard handling your vessel is subjected to both during and out of the boating season. From rough mooring conditions to collisions with other vessels—your boat is at constant risk of damage.
So what can be done to ensure your boat is as protected as can be? Let’s find out.
What Equipment is Needed to Protect Your Boat?
And when it comes to protecting the interior of your boat you are spoiled with choices from products like UV protectors to protect your boat’s seats from sun damage and special waxes to do the same for its floor.
But what about the exterior of your boat? One of the best ways to protect the exterior of your boat is by using fenders or bumpers as they are sometimes mistakenly called. For some reason, fenders are often overlooked and definitely underappreciated.
Whether your boat is a beat-up dinghy or a brand-new Catamaran it will benefit from having fenders.
Boat Fenders: What do They do?
Boat fenders serve a very important purpose. They essentially have a cushion-like effect on your boat. Boat fenders act as a buffer between a boat and anything it might hit such as other boats, seawalls, pilings & docks.
It’s specifically designed to absorb the shock of an impact and does a great job at doing so. Fenders can be used on any vessel in any body of water be it a lake, a river or an ocean.
Fenders are a huge source of protection for your boat and who wouldn’t want to protect their investment?
The Different Types of Boat Fenders
Contrary to popular opinion a boat fender is technically not the same as a bumper, although both products serve the same purpose. The difference is that a fender is attached to the boat whereas a bumper is secured to the dock.
There are many different types of boat fenders available on the market. Knowing the different types is an essential factor in picking the right type for your boat. We’ll be looking at the four most popular types of boat fenders below.
Cylindrical Double Eye Fenders
Cylindrical double eye fenders are some of the most popular types of boat fenders because they’re perfect for the smaller vessels that the majority of boat owners own. These fenders are most often hung in a vertical manner but, provided you have two fender lines available, can also be hung horizontally. Some models feature a ribbed design for reinforcement.
Cylindrical Center Hole Fenders
Cylindrical center hole fenders are better suited for larger vessels. These fenders provide more cushioning than cylindrical double eye fenders. They’re almost always hung horizontally but can be hung vertically using a fender line through its middle, with figure-eight knots securing both ends.
A round fender is a soft fender that is most often found on larger vessels that have flared bows. Round fenders are also often used for rafting two boats together. These are the fenders that you’ll often see adorning the sides of commercial fishing boats.
Hybrid Cylindrical Round Fenders
As you may have guessed by the name a hybrid cylindrical round fender combines the characteristics of cylindrical fenders and round fenders. These fenders are best suited towards larger, heavier vessels.
Specialty fenders are designed to be used in specific mooring conditions. They can be designed for boats with low freeboards to protect the rub rails and gunwales. A transom fender is a great example of a specialty fender as it is specifically designed for a boat’s swim platform.
How to Choose the Right Size Boat Fenders
Choosing the right sized fenders for your boat is surprisingly simple. Keep your boat’s weight, length, and typical mooring conditions in mind & you’ll be able to make an educated decision. The rule of thumb is that for every 4’ to 5’ of a boat’s length a fender of a 1” diameter should be in place.
How Many Boat Fenders Will I Need?
When it comes to boat fenders, the more your boat has the better off it will be. It’s not only recommended to have multiple fenders aboard but to have more than one type so that you’re prepared for different situations and mooring conditions.
The general recommendation is that boats measuring up to 10 meters long should have two fenders on each side of the boat while boats longer than 10 meters should have four fenders per side.

Everything You Need to Know Before Buying Boat Fenders
Before taking your pick from the seven brilliant options above there are a few aspects to consider to help you make the best decision possible.
What are Boat Fenders Made of?
Generally speaking, boat fenders are made with durable materials such as rubber, plastic, elastomer or foam. You need to ensure that the materials used to construct your boat fender are high quality, durable and can withstand the effects of both sea & sun. Here’s an interesting fact for you: back in the day boat fenders were fashioned out of woven rope and this is still practiced today by older boat owners with a passion for boat history.
How to Hang Boat Fenders - Vertical vs Horizontal
Fenders should be hung in such a way that the bottom of the fender is just skimming the surface of the water. This is to limit marine growth on the fender and also to prevent the dock from pushing the fender out of position. Some fenders are specifically designed to be hung either vertically or horizontally while others can be used for both.
The deciding factor as to whether you should hang your fender vertically or horizontally is as follows:
- Vertical hanging: Ideal for when your boat is mooring against flat structures such as docks
- Horizontal hanging: Ideal for fending against pilings and other protruding structures
How to Attach Boat Fenders on a Pontoon
Because a pontoon has equal beam width spanning from bow to stern, attaching boat fenders onto one can be difficult. You can use fender clips anywhere on your pontoon rail but this isn’t possible for all pontoon boats. As an alternative to fender clips here’s a DIY approach you can try:
- In freshwater environments, it’s recommended to use spring links to clip the fenders into place
- In saltwater environments, you can use the same spring link method you’ll just need to use stainless steel bolts and components.
How to Adjust the Pressure of a Boat Fender
Knowing how to adjust the pressure of your fenders is crucial. This is because when a fender has either too much or too little pressure it won’t protect your boat effectively. Always check what your user guide recommends as the ideal pressure level for your fender, but a safe bet is to use a pressure of 1-2 psi.
You can adjust the pressure using a boat fender pump or a standard hand or foot pump. You can also make use of an air compressor or service station air pump if you have access to one. Some models, such as Polyform fenders, require specific pumps so keep that in mind when making your purchase.
While this process varies slightly across the different models, here’s a quick overview to give you a general idea of how to adjust your boat fenders’ pressure.
If a plastic screw or cap is present, remove it. Place the air pump on the metal valve and make sure the openings of the valve & the nozzle are aligned.
Begin blowing air into the fender. When a fender is properly inflated it will retain its shape, won’t bulge at the sides and will feel firm.
Once you’ve increased the pressure remove the inflation device and if you removed a cap or screw, gently screw it back in place. Using too much force will result in damage to the valve.
If a plastic screw or cap is present, remove it. Insert a long, thin, blunt object such as a hex key, pen or piece of stiff wire, into the valve. This will disengage the backflow prevention flap.
Apply slight pressure to the body of the fender to squeeze the desired amount of air out of it.
Once you’ve decreased the pressure remove the inflation device and if you removed a cap or screw, gently screw it back in place. Using too much force will result in damage to the valve.
How to Clean Boat Fenders
Boat fenders can be cleaned with a simple solution of soap and water. Stay away from cleaning agents that contain harsh ingredients, such as acetone, that will cause damage to your fenders. If you want to avoid cleaning your fenders entirely then washable boat fender covers were practically made with you in mind.
