Whether you are a yacht Captain, an Engineer, a yacht manager or the owner…

You need everything to be PERFECT on key dates. You make important decisions, you have a lot of responsibilities and it’s not easy to organize a lot of tasks, people and suppliers and it’s not easy to organize a long list of suppliers and all the various people working on the multiple jobs that have to be done.

We can help you

We all hate contingencies, bunglers and providers who don’t do what they say. It is critical to have the boat in perfect condition for the navigation dates. That’s why everything that causes delays, goes over budget or gets off schedule can be so stressful.
