What makes a good fender?

Poor Quality Fender EyePolyform F Series Eye
  • The toughest fenders have a solid eye and are made in a single piece so it would be virtually impossible to break.
  • The eye should be smooth on the inside so the fender line does not snag and wear through.
  • Inflated eyes should have built-in re-inforcement and a smooth finish.
  • There should be no rough seams which may cause abrasion or could even split apart
  • Avoid fenders which have painted ends. The paint is liable to leave marks on the boat and the other fenders.


 

    F Series Wall ThicknessG Series Colours
  • The walls of the fender should be 4mm thick all over. Any thin spots will be weak spots.
  • The walls of the fender should be smooth not knobbly or rough and there should be no "gas marks" which are small circular indentations where the air has been trapped between the mould and the paste.
  • The colour of the body and the eye should be resistant to UV so should not fade in the sun or go sticky. Sticky patches on fenders can  never be removed permanently, they will always return.
  • You should not use thinners or white spirit to clean fenders or try to remove stickiness as this will cause the material to degrade further
  • Polyform US Fenders


    Polyform US have been making fenders for over 50 years and set the standard for the industry.
  • The F series have a solid eye, 4mm thick, smooth walls and are colour-fast.
  • The G series have an inflated eye with smooth, built-in re-inforcement. The walls are 4mm thick, ribbed to minimise abrasion and smooth. They are also colour-fast.
  • The HTM series have the same qualities as the G seies but with a hole through the middle instead of eyes.
