A yacht's running gear is constantly subjected to load, impact, vibration, and wear. Most issues develop gradually before becoming obvious underway. Common symptoms:
Vibration underway.
Reduced acceleration or top speed.
More throttle required for normal cruising speed.
Increased fuel consumption.
Unusual noise from below the waterline.
Steering irregularities.
Changes in handling characteristics.
Signs of previous impact or grounding damage.
Recurring vibration despite previous repairs.
The challenge is identifying the true source before unnecessary repairs, repeat haul-outs, and ongoing performance issues follow.
We regularly inspect vessels where propellers have already been repaired or replaced, yet vibration remains. Common causes:
Shaft misalignment.
Cutlass bearing wear.
Strut movement or damage.
Grounding-related distortion.
Propeller imbalance.
Rudder issues.
Engine and drivetrain alignment concerns.
Hull damage affecting running gear performance.
Multiple smaller issues creating a larger problem.
Reliable performance depends on understanding how the entire system operates together, not simply replacing the component that appears to be causing the problem.
Propellers, shafts, bearings, alignment, hull condition, and drivetrain performance all influence one another. That is why a systematic approach matters, and why our in-house team works across disciplines.
Fault finding that looks at the whole system, not just the obvious part.
Propeller, shaft, bearing, and alignment work sequenced on one plan.
Work planned around vessel schedules and yard periods.
System work coordinated cleanly alongside refit scopes.
Consistent standards held across every stage of the work.
A smoother, more controlled repair process from start to finish.
Minor vibration, performance loss, or unusual noise rarely improves with time. What begins as a slight annoyance can increase wear throughout the drivetrain, reduce efficiency, and lead to more significant repair costs. Catching it early means simpler repairs, lower cost, and less disruption.
