Checking and replacing the tendon on your mast base
It’s that time of year to check out your gear. Cold water sailing is fun and exhilarating but a little more care should be given to safety. Here is a quick guide to checking and changing one of the most critical parts of the rig. The mast base (Universal joint). I have three. All three of the tendons holding it together needed to be replaced. I am changing them twice a year now. They cost $25 a piece but can save you and your gear. When they break… often the board gets damaged at the same time. Imagine loosing a part of your gear… sail or board!!! Spend the money… its worth it. Bruno at 2rad has them in stock.
Dont forget to check the line that holds it all together. You can sail back with this setup even if the tendon breaks.
To check the mast base tendon you need to disassemble it. Mine are done with an Allen key.
Insert a thin screwdriver shaft into the hole that holds the screw.
Bend the screwdriver up and down and check for cracks on both sides of the hole. This is a fairly huge crack, If you even see a nick, its time to change it.
