Frequently Asked Questions

What’s included in a full running gear inspection?

We evaluate cutless bearings, shaft condition, alignment accuracy, propeller status, seal performance, and vibration levels.

How often should I service my running gear?

We recommend annual inspections, as well as before or after long-distance trips or scheduled haul-outs.

Do you work on-site or only in dry dock?

Both. We provide on-site mobile services and also assist with haul-out projects in shipyards or marinas.
