Technical Diagnosis: Bent Hobie MirageDrive Fin Mast

The bending of your Hobie MirageDrive fin mast is almost certainly (85% probability) due to a violent impact against a submerged obstacle. This causes plastic deformation of the steel, which manifests as the fin rubbing against the kayak hull, making pedaling stiff and asymmetrical.

If you notice that the fin does not return to alignment correctly or struggles to swing freely, the mast may have lost its original linearity. Continuing to force pedaling under these conditions risks premature wear of the fin rubber and damage to the sprocket housing.

Quick checks:

1. Inspect the fin tip and the hull keel for obvious scratches or abrasions.
2. Visually check the mast to locate the point of maximum bend, usually near the connection to the sprocket.

Key signs: A previously straightened mast (10% prob.) can bend or break easily due to work hardening. Excessive play in the sprocket (5% prob.) can promote bending.

Common mistake: Attempting DIY straightening in-situ is risky; it can damage the sprocket or make the mast even more fragile.

Conclusion: If the mast is visibly bent and the fin is not torn (85% prob.), replace the mast to restore functionality and prevent further damage to the hull; if in doubt or if the fin is damaged, consult a technician for a professional evaluation and bench straightening, if feasible, or complete replacement.
