Kites and corrsion

For the past few years, I almost only flew Dan leigh Kites or Kap Foils and neglected my flow forms 16, 16 becotized, FF 30 and FF 8 which all flew from 2005 to 2010 in some severe marine environment and were stored after a complete fresh water cleaning and sun dry.
Almost 7 years later on a sunday morning I decided to do a check and opened them under the tahitian sun; much to my surprise I found out that all metallic parts were corroded to a point that they all broke loose and needed to be removed to stop the corrosion process.
The Flow Forms are now back in their bags for an other few months or years and I have changed all metal parts by dyneema lines.
If you fly your kites by the ocean or if you live by the ocean, like we do, make sure you replace all metal parts by a line.
The two large blue Peter Lynn Lifters did not have any metallic part and were absolutely fine.

  • thanks Pierre Lesage for sharing,

    I have looked to the pictures and seems clearly that corrosion was concentrated at metal just out of bridle knots

    Alu alloys suffer marine salty humidity (living in Tahiti must have some few little negative point...)

    salty humidity on line and air oxigen on free metal surface very close to knot = concentrated corrosion

  • Very interesting. Most of mine are chrome plated steel and I have one brass ring ( but It's not holding the pull of the kite).
    Wonder if they make anodized aluminium rings or stainless steel one.

  • Salt and water (or humidity) is a tough mix with metal....

    I have moved to all stainless steel components for my stratospools......primarily due to sailing / kayaking in oceans!
