Baller SundevilSki Posted May 21, 2017 Baller Share Posted May 21, 2017 Just thought i'd share. This is an old, beat up pair of team jumpers that had known water intrusion issues and a side rail that popped off after every set. When they finally bit the dust, I pulled them apart to see what the nasty salt/alkaline water at our lake did to the core and yes they were washed after every set Link to comment Share on other sites More sharing options...

Baller Mateo_Vargas Posted May 21, 2017 Baller Share Posted May 21, 2017 Electrolysis from the dissimilar metals. When stainless steel contacts aluminum the aluminum becomes sacrificial. Link to comment Share on other sites More sharing options...
Baller eleeski Posted May 21, 2017 Baller Share Posted May 21, 2017 If those are the skis I repaired years ago and wrote "do not jump with these skis" as the warning associated with my repairs, they held up really well. If the skis I repaired are still around, definitely do not jump with them! Honeycomb cores have limits. Salt water is harsh. Rinsing is overrated.

Baller Keith_Menard Posted May 22, 2017 Baller Share Posted May 22, 2017 Firebird is the most corrosive water I have ever seen. It destroys boats and anything else it comes in contact with! Link to comment Share on other sites More sharing options...

Baller tap Posted May 22, 2017 Baller Share Posted May 22, 2017 Nice! The term you're looking for is galvanic corrosion. It's the interaction of the carbon, aluminum, and salt water that's making the magic happen. In this case the carbon skins are the cathode and the aluminum honeycomb core is acting as the rapidly corroding anode. Basically you turned your skis into batteries. It's the same reason aluminum fins and fin blocks get all chalky where they contact the carbon skins of a slalom ski. The process still happens in fresh water, just at a much slower rate that no one really cares. Salt water is a way better electrolyte. Link to comment Share on other sites More sharing options...
Baller keithh2oskier Posted May 23, 2017 Baller Share Posted May 23, 2017 So @SundevilSki your team jumped on these skis until you decided to retire them? What caused them to finally bite the dust? Man I miss college waterskiing. Link to comment Share on other sites More sharing options...
Baller Keith_Menard Posted May 23, 2017 Baller Share Posted May 23, 2017 @keithh2oskier I miss college! I went to Arizona State (they just tore down my residence hall)...man I wish I knew about competitive waterskiing back then...but on the bright side, I got a LOT of free skiing at Powell.

Baller SundevilSki Posted May 24, 2017 Author Baller Share Posted May 24, 2017 @keithh2oskier I was the only one crazy enough to jump on them. I liked those skis but it got to a point where I was gluing the rail back on after every set. Once the carbon fiber on the bottom started to peel, i figured it was time for retirement Link to comment Share on other sites More sharing options...
