Comprehensive boatyard facilities
Located on the north-west corner of St. Sampson’s Marina, our spacious yard, workshops and covered boatshed allow us to work on vessels throughout the year.

As the authorised service centre for Volvo Penta, Yanmar and Nanni, we maintain and repair all major types of inboard marine engines. Our factory-trained engineers stay up to date with the latest technologies and diagnostics to ensure expert workmanship and lasting reliability.
Our skilled shipwrights carry out a wide range of marine repair and finishing work, including gelcoat and fibreglass repairs, carpentry, stern gear and propeller repairs, polishing, antifouling and Coppercoat applications.
As the Channel Islands’ only Lewmar Gold Installer, we can supply and fit the full Lewmar product range with precision and care, ensuring top-quality performance and reliability.
Access to St. Sampson’s Marina is tidal, so entry and exit are limited to certain times. Please contact our office before arrival for up-to-date tide times and navigation guidance.
