7seas Maritime is covered by a P&I Insurance Policy, which guarantees that all engineers, employees, and contractors are properly certified for the specific task they carry out on your yacht.

Our Engineers and their respective specialist technical teams are here to ensure that you relax during your yacht’s maintenance time. They carry out specific surveys to identify any problem and provide the best solution for them.

Furthermore, we carry out annual surveys to identify all problems that need to be repaired and keep a record of your vessel’s sea worthiness, which will enhance the investment value.
