A Captain's Feel for Mechanics

After 15 years at the helm, you don't just hear an engine; you feel it. You know the subtle vibration that comes before a failure.

We bring that captain's intuition to every mechanical service. We go beyond computer diagnostics to understand the real-world performance of your engines, steering, and running gear, ensuring your vessel is not just 'fixed,' but truly sea-worthy.
