With the following tips & guidelines we will help you choose the perfect set of Rope Fenders for your boat. 
We will help you choose in 3 Steps. Let's get started!  




The right shape in the right size 

Cylindrical fenders:
This is the most commonly used fender. You can't go wrong with this model when it comes to safety. However, as the diameter of the fender increases, so does the length. If your boat lies relatively deep in the water, cylindrical fenders could hang in the water. Fenders that hang in the water are a big no-no in terms of nautical etiquette ;) and it is bad for your fenders! If they are too long, choose to suspend them horizontally, or go for our short Danny (single eye) fenders! View in webshop.

Single eye fenders:
Our single eye 'Danny' fenders are short, but have a relatively big diameter. They can offer the right amount of 'cushioning' without touching the water. View in webshop.

Step 1: Find the recommended size.
Take a look at the table below to see which fender size is recommended for the length of your boat.

Choosing the right number of fenders

The amount of fenders needed depends on the length of the boat and the mooring conditions.

Step 2: Consider the length of your boat:
Generally speaking; the longer the boat, the more fenders you will need
There is a rule of thumb to determine the number of fenders a boat needs: Use one fender per 10 ft or 3 meters of waterline, with a minimum of three fenders. So a 20 ft or 6 meter boat would need 3 fenders. A 40 ft or 12 meter boat would need 4. At least one fender must be placed at maximum beam, with others distributed fore and aft.

Step 3: Consider the mooring conditions 
The amount of fenders you need also depends on where you moor. Do you need protection on on side or on both sides? 

Are you mooring in rough ocean conditions or do you moor in a quiet pond in your back yard. If mooring conditions are harsh you might want to choose fenders that are relatively big for your boat. 


Use common sense

Choosing fenders is not rocket science, and also not an exact science. The tips and guidelines on this page give a pretty good indication of what you need. However, you should use common sense. If you think the conditions you moor in require an extra fender, or if you want to protect a specific part of your boat, you are probably right in doing so! Trust your gut feeling! 

What fenders do similar boats use?
If you are in doubt about the model, size or number of fenders you need. You can always look at the fenders that boats similar to your boat are using.
