What this video covers

Mud packed inside a hollow roll bar is corroding a galvanized Rachna anchor from the inside out, causing the metal to rust, flake, and scale.0:10 The anchor is roughly 20 years old, but the problem applies to any brand of galvanized hollow roll-bar anchor: mud from certain seabeds packs into the roll bar through its end holes and traps moisture against the steel.0:26 On the topside of the roll bar, heavy rusting has caused visible bulging that Steve Goodwin judges is close to fully perforating.0:33 Once perforation begins, the roll bar will eventually collapse.0:38 The fix is straightforward — flush and clear mud from the roll bar after anchoring in muddy seabeds to prevent internal corrosion from taking hold.0:44
