Hauraki Inflatable Fenders

As a guide, we recommend every boat should always carry at least 3 fenders onboard (larger boats should carry 4-5).  The size of fender mostly depends on the length and design of your boat, but ultimately it comes down to personal preference and how the fenders are going to be used. 

When selecting the size and quantity of fenders for your boat and the following points should be taken into consideration:

  • The length of your boat.
  • How much freeboard your boat has, the height of its top sides, and where the fenders will be used on the boat.
  • What are you rafting up to (wharfs or other boats) and where you are rafting (calm waters or waters prone to waves or boat wakes). 
  • The displacement of your boat.  Lighter weight boats can be at the lower end of the size spectrum while heavier boats should be at the upper end.
